Difficult to distinguish between heat stroke and corona infections [It's the latest warning for very similar early symptoms].

Weather

With the hotter weather in full swing, this is the time of year when the number of heat stroke cases will also increase. In addition, the new coronavirus infection is not yet at a safe phase. In this article, we will discuss the symptoms and precautions for each of these diseases.   About Heat Stroke Heat stroke, formerly known as sunstroke, heatstroke, or heat exhaustion, is a disease of hot environments and body temperature. It is a condition in which the body becomes abnormal in an environment that is difficult to lower. .   A hot environment is one in which you exercise or are active in the hot sun and your body temperature is not likely to drop. is an environment where, for example, the elderly spend tropical nights at home without air conditioning, and I think this is widely recognized. I think this is widely recognized.   The cause of heat stroke is an imbalance in the body's thermoregulatory functions due to an increase in temperature. It is the accumulation of heat in the body. By nature, the human body raises the temperature of the skin and sweats to release heat from the body When that fails, heat stroke can occur. . .   Symptoms of Heat Stroke The main symptoms of heat stroke are headache, general malaise, high fever, dizziness, dizziness, muscle aches and pains, hot flashes, etc. There is. In severe cases, the patient may develop disorientation.   When I was living alone in the past, I couldn't help but sweat differently in the middle of the night. and was unable to move and called an ambulance. As a result, it was determined that he was suffering from heat stroke with dehydration.   There is a disease that can easily be complicated by heat stroke. It is rhabdomyolysis (Oumontomyolysis). Symptoms include muscle pain, stiffness and muscle weakness, but it can also lead to kidney failure.   Heat stroke, as well as rhabdomyolysis, can be life-threatening. I hope you can understand.   Points to keep in mind in daily life regarding heat stroke I recognize that this is a common and well known way to prevent heat stroke.   Drinking frequently, using air conditioning, and wearing clothes that won't trap heat. There was once a time when students were not allowed to hydrate in athletic clubs, but nowadays it is unthinkable Right?   In addition to the above, I recommend a thermometer (preferably with a hygrometer) for the room. to keep the temperature of the room at an appropriate level as an objective number, not a physical one, and to make sure that the temperature is kept at an appropriate level just in case The idea is to have a card with emergency contact information in a place where you can find it. In my case, I keep a card the size of a business card with my contact information and blood type in my wallet, and I have a card in my wallet for my family. Sharing. If you have another disease, you can include the name of the disease, and if you have a medication you are currently taking, you can also include the name of the drug. I think it's more secure.   About coronaviruses The corona, as some of you may know, is the coronavirus for the common cold There are four types by now. So they are not uncommon. The coronaviruses mentioned above are mostly found in children, and it is common for children to experience infection by the age of 6. Known for. After that, SARS and MARS also shook the world, but this was also the first time that a conventional coronavirus had been used to cause a It is a mutation.   Coronaviruses have a lipid film on the surface of the virus, known as the envelope, and the corona ( Coronaviruses are named after the shape of their protein projections, which look like a crown. The number of coronaviruses reported so far, including SARS and MARS, is six. .   Symptoms of the new coronavirus As for the new coronavirus, it is the seventh coronavirus to do so. Neither the new coronavirus nor the severe acute respiratory evidence group (SARS) nor the Middle East respiratory syndrome ( (MARS) are almost always similar in their main symptoms.   , new coronavirus - high fever and fever -Severe acute respiratory syndrome (SARS) - High fever and fever. Diarrhea. Middle East Respiratory Syndrome (MARS) - high fever, pneumonia, nephritis, and diarrhea   Incidentally, when it comes to seasonal flu (which is also viral), high fever, headache, and Many of you know that you may experience symptoms such as joint pain. In the early season, the flu starts to spread in September, so be careful not to confuse the two. is. New coronaviruses are often asymptomatic, and asymptomatic patients who remain asymptomatic and get well = "asymptomatic pathology It is now well known that there are also many "body-holders". In the early stages when symptoms begin to appear, there are a number of symptoms such as taste and smell disturbances, coughing, headaches, and general malaise Some people may have only symptoms and get better without a high fever.   I had a phlegm-laden cough for about two weeks around April. I was not able to get a PCR test at my medical facility, so I had a corona infection. I don't know if I have (and still hold) I have had no other symptoms and I've had a mild recovery, so I'm very aware that self-judgment is not a good idea. We have been at this point in time.   Communications of coronaviruses Human-borne droplet and contact transmission is known. As with dengue fever and rabies, there is a consensus on whether it can be transmitted from insects or animals to humans. It is still unknown.   Coronaviruses are so small, just 0.1 micrometers, that they are impossible to see. Cedar pollen is 30 micrometers long. Can we see cedar pollen? By the way, the cells that make up our body are 10 micrometers in diameter. Although you may not normally see them, human cells can only be seen with a microscope. It's no surprise that coronaviruses are invisible and their particles are very fine.   Although many of you may have heard in the press that the route of infection is unknown, the It is very difficult to identify the route of infection.   Countermeasures against coronavirus infection A worldwide call to avoid "honey" has been made by countries and municipalities As I'm sure you are aware of, various clinical trials are being conducted in the U.S. and around the world, and they are being published one after another. Various clinical trials have been conducted in the U.S. and around the world, and the results are being published one after another. There is no cure or vaccine for the disease. You can do what you can do as an individual to minimize contact with people, use a mask or face guard, etc. You should do this and take measures to avoid getting infected and not letting it happen.   When a drug or vaccine that has been shown to be somewhat effective is approved and guidelines are established I think it's vital that we live according to the so-called "new way of life".   Why is it so difficult to distinguish the symptoms of heat stroke and coronavirus infection? Similar symptoms of heat stroke and coronavirus infection include fever, sweating, and You may feel funny, lightheaded, and general malaise. You might think it's heat stroke, but it's a symptom that can also occur in the early stages of coronavirus infection.   Also, even if the fever is not extremely high, if the fever is higher than normal, it is difficult to identify even a slight fever. It seems to be the case. If you are able to express yourself, you can complain of other symptoms as subjective symptoms, but Still, it is very difficult to make a decision, and there is a danger in making a layman's decision. If you encounter a person who is not able to express his or her intentions properly, he or she may not be able to take measures against heat stroke. It's hard to know if he was or was not taking measures to prevent corona. Either way, it's life-threatening, and it's possible that it's not heat stroke or coronavirus infection. There is. Therefore, it is very important to contact the appropriate medical institutions and consultation services as soon as possible. It's important.   As you know, PCR testing is necessary to identify whether a person has coronavirus infection Therefore, even professional doctors cannot make a definitive diagnosis based on clinical symptoms alone, especially in patients with comorbidities. Therefore, even professional doctors cannot make a definitive diagnosis based on clinical symptoms alone, especially in patients with comorbidities. In the case of the three patients, they are reluctant to do so. Of course, if the PCR test is positive, the coronavirus infection is confirmed, but the result is Because of the time lag until we know, we can't intervene in treatment while we're waiting, and the doctors I know. I've also heard of several cases that are hard to distinguish. From the above, you can see how difficult it is to distinguish between heat stroke and coronavirus infection. I think.   This is because of the similarity of the initial symptoms, especially in both diseases, but it is not until after the disease has become severe that Appropriate action is still necessary at the early stages of the disease, when the symptoms are similar, as there is a risk that it may be too late. I think so. With coronavirus infections not yet converging, the hot summer is coming to a point where it is difficult to identify Symptoms will be more common.   I'm sure all of you are taking great care in your lives, but it's not just you. Please be aware of minor changes in the physical condition of your family members and others around you, and keep in mind the difficulty of identification. We hope to be able to provide you with the best possible service. .   Points to keep in mind in daily life regarding coronavirus infection Although the measures mentioned above are true. In addition, the lack of a cure, reinfection, and reactivation of the virus has been noted. Each of us should try to live a life to avoid infection and be aware that we may be a carrier of the disease. and should be more aware of "living without infection". Coronavirus is an infectious disease, unlike heat stroke. As an infectious disease, it's important to be aware that it's more than just your problem.   Summary More than six months have passed since a new type of coronavirus infection was first reported, but there is no sign of an end to the outbreak. But there is no sign of containment, and experts say that the second and third waves of the disease, originally held this year Next year's Olympic Games are also in jeopardy.   Furthermore, during the year, or one year, since the outbreak of the new coronavirus itself, the Under what conditions does the environment become more or less infectious, or is it unaffected by the external environment? It has not been verified. From winter to spring, and even now, the new coronaviruses have spread in a pandemic, spreading around the world people are using masks, staying away from the house, staying away from people and trying to disinfect.   Japan has just passed the rainy season and is about to enter the summer season in earnest. We are entering a period of increased heat stroke. Under the current circumstances, where mask wearing rates are clearly higher than they were this time last year, the risk of heat stroke is higher than normal. It's easy to imagine that the number of heat stroke cases will rise this year as the number of heat stroke cases increases. I drive around a lot, and this time of year the rate of encounters with ambulances is high every year! I think it is. I suspect that more and more people are calling for emergency services due to heat stroke.   The number of people being transported to the emergency room for heat stroke has exceeded 50,000 in most of the years in recent years, according to the Ministry of Internal Affairs and Communications. The number of deaths is over (between May and September), and some of them are dying. Half or more of them are over 65 years old. A very large number of people are rushed to the emergency room every year due to heat stroke. Moreover, this is only the number of people transported to the emergency room, and there is a discrepancy between this and the actual number of heat stroke patients.   More than 20,000 people in Japan have contracted coronavirus so far, with 1,000 Nearby people have lost their lives. Even after the state of emergency declaration was lifted, the number of new cases of the disease has been on the rise lately, and at first, the number of new cases was I have to be skeptical of the possibility that "the virus goes dormant when the temperature and humidity rise". . .   Globally, on a WHO-reported basis, the total number of people has increased to about 12 million, 550,000 A man nearby has lost his life. What do you think of this situation? What do you think of this situation?   One of the high risk factors for severe coronavirus infections is old age. It is suggested. Considering these aspects, not only for you, but also for the elderly in Japan, heat stroke and coronavirus infections are more of a concern than ever. I urge you to pay attention to the elderly around you as well. Needless to say, not only for the elderly, but for all people. That is, not just for the elderly, but for everyone.   As mentioned many times, the early symptoms of heat stroke and new coronavirus infection are similar in some ways. In many cases, it is extremely difficult to distinguish between them based on subjective symptoms, other symptoms, and clinical symptoms alone. It would not be an exaggeration to say that it is impossible. As the temperature difference between the cold and the cold, and the summer is gradually approaching in earnest, it is important to reiterate once again that heat stroke and the new corona Rethinking the early signs of viral infections and taking appropriate action is a good way to make sure that you and the lives of your loved ones, in my opinion.

Athlete's Foot and Caterpillar Problems During the Rainy Season! Could ringworm be the cause of the outbreak?

Weather

The epidemiology, causes, treatment and remedies of athlete's foot and caterpillar from the perspective of medicine and pharmacology in an easy to understand manner. Introducing. In addition, I would like to talk about ringworm and ringworm (hereinafter referred to as "ringworm") by sharing my personal experience. Introduction.   About Epidemiology In medical terms, athlete's foot and ringworm are collectively referred to as ringworm. The so-called athlete's foot is called tinea pedis, while the so-called ringworm is called ringworm of the body. (Massive white line)". Tinea pedis increases during the rainy season (after May). The incidence decreases as the winter season begins. According to a survey conducted in July, one in four Japanese people suffer from ringworm of the foot. On the other hand, there is another type of onychomycosis called ringworm of the nail (athlete's foot). Tinea nails can occur at any time of the year, and there are more than 10 million people in Japan who have ringworm on their nails. In addition, there are reports of a higher incidence rate in males than in females in terms of sex ratio. In addition, in terms of the ratio of males to females, there are reports of a higher incidence rate in males than in females. Both tinea pedis and tinea corporis have been reported to increase in incidence with age, especially ringworm of the nail In addition, the data shows that 40% of people over the age of 60 are affected by the disease. When it comes to athlete's foot (tinea pedis), it's important to note that it can actually occur in younger people as well as older people Hey.   What is athlete's foot and ringworm (ringworm)? Theria pilaris is a skin infection caused by dermatophytes . In other words, it's not a virus or bacteria that causes it, but a fungus called ringworm. A fungus is what is called a mold. Trichophyton can be a fungus that reproduces on a protein called keratin as a nutrient. The place where most keratin is present is in the keratin that covers the surface of the skin. The keratin is the epidermis that is being reborn as a plaque. Therefore, the surface of the skin is the main site of predilection for ringworm. The mucous membranes do not have a lot of keratin, so ringworm will not develop in the mouth. The site of onset of athlete's foot is called tinea pedis, which is the sole of the foot and between the toes. As for ringworm (tinea corporis), it is a ringworm infection that occurs on the skin of the face, trunk and extremities. It may occur in the neck area, or at the nape of the neck, and may be widespread. And since the altered stratum corneum becomes the nails and hair, ringworm can infect the nails and hair. The following is a brief description of the process. Ringworm is an infection of the nail. There are many different types of ringworm. There are other types of ringworm than the ones listed above. Ringworm is notoriously difficult to detect when asymptomatic. If a ringworm (ringworm of the body) develops on the back, if I didn't have any symptoms, I would still be pointed out to others and Unless, I don't think you'll notice it yourself.   Causes of Athlete's Foot and Caterpillar Infection The causes of ringworm infections are the opportunity to come into contact with ringworm fungus and the prolonged exposure of the fungus to the skin This is due to stagnation. There is no single causative organism, there are many species. Normally, ringworm fungus does not appear as a symptom. However, during the rainy season, especially when the environment is hot and humid, the fungus begins to multiply and It manifests as symptoms of blistering and itching. Although it is the main cause of athlete's foot (ringworm), during the rainy season, especially during the rainy season, ringworm carriers can be found in the home ( (e.g., bedding and carpets) or outside the home (e.g., public slippers and spa facilities). The most common route is the spread of ringworm to non-carrying individuals in . It is the main cause of ringworm (tinea corporis), but since it is caused by the same fungus as athlete's foot, if you have athlete's foot It can spread to the body, or if a family member has athlete's foot, it can be transmitted in the home. It is possible. Another route is to infect humans through contact with dogs and cats infected with ringworm. I am also a carrier of athlete's foot (tinea pedis) and it appears as a symptom every year starting around June. No matter how much I think about it, the route of infection is unknown. Since it is invisible, it can be transmitted anywhere and at any time.   The Danger of Self-Determination In fact, if you search the Internet and other sources, you can check yourself for ringworm . I think this is one of the things that will help you. However, in my experience, for several years, I've self-judged that it's probably ringworm, and I've been using over-the-counter treatments to treat it. It was supported. Certainly, it was effective. But every year during the rainy season, the same ringworm symptoms would recur and I would ask, "Did you still have ringworm? This was a period of several years. I don't want to have to go through this kind of unpleasantness every year, and I've been told by the clinic that I have ringworm-like symptoms. Would you mind? I felt somehow embarrassed to see a doctor, so for several years I decided to call it ringworm (athlete's foot) by myself. I had decided to use a spray-on over-the-counter medication for symptomatic treatment. As mentioned above, there was a certain amount of effectiveness. But to begin with, the over-the-counter athlete's medications you buy at the drugstore are generally more expensive. The most important thing I would say is that it is important not to make a layman's judgement, because if you have ringworm, let's say you have ringworm. Because, in layman's judgment, let's say you have ringworm. Even with over-the-counter medications, you'll find that, rather quickly, the itching is gone, the blisters have disappeared, the pain is gone. The effects of the treatment are as follows: "I don't have pain in my body anymore" and "My limp appearance seems to have improved. There are some people who show up. On the other hand, there will be a certain number of people who say, "I applied it yesterday and I don't feel like it's healing". The worst thing you can do there is to "stop the treatment on your own". This is exactly what I was doing. Once the symptoms went away, I stopped treatment. He diagnosed himself as such, sprayed or applied medication as such, and cured himself at his own discretion. And then we interrupt. This is what causes relapse. In the case of a couple of friends of mine, I would say that their husband, who is in his 30s, has athlete's foot, and he leaves it every year. I was there. In June of this year, the wife asked me if I might have athlete's foot... I am not a doctor, and I would like to see this couple for a medical consultation and to make an accurate diagnosis and give them medication. I recommended that you receive it. In this case, the most likely route of transmission would be home transmission. However, we don't know the details of his life, so we don't know where he actually got the infection. Right. Now you know how risky self-judgment and self-treatment can be.   Treatments and Drugs First of all, if you suspect ringworm, ringworm, or ringworm yourself, you are strongly advised to seek medical attention The following is a brief description of the process. This is because a professional doctor will diagnose and prescribe the right diagnosis for you. Basically, your treatment and medications will be determined at the discretion of your doctor. Most of the antifungal medications are prescribed for you. In Japan, creams, liquids, sprays, and ointments are the most common types of medications approved for use in Japan. It is also reimbursable by insurance. In some cases of ringworm (tinea corporis), steroids may also be prescribed. Depending on the symptoms, oral antifungal medications may also be prescribed. Other injections are also available, but injections are generally not used to treat athlete's foot and ringworm. All of the antifungal agents listed above are directly effective against the fungi that live in the outermost layer of the skin. things. Each has a different role, so your doctor will prescribe the right dosage form of the drug for your condition. For example, with creams, ringworm between the toes, ringworm with blisters and squishy ringworm, soles of the feet It is suitable for thick, keratinized ringworm of ringworm. In liquid form, it is better for unblistered, flaky ringworm on ringworm. In the spray form, it is more suitable for ringworm that has spread over a large area. We encourage you to see your health care provider and have him or her prescribe the right medication for you. If you're like me, it's definitely better to start treatment as soon as possible rather than having to worry about it for years. I am embarrassed. In fact, I finally saw a medical professional last month and am still applying the ointment that was prescribed to me, even now that my symptoms have subsided. Amateur judgment is dangerous. Following my doctor's instructions, I will be applying it for a little over a month. After all, I am usually happy when the itching, which was my main symptom, goes away.   How to deal with it To avoid a repeat of athlete's foot or ringworm, take the following precautions. You may think it's obvious, but it's so important that we've included the following as a refresher course. The following is a brief description of the process. Even if the skin symptoms disappear, the prescribed medication must be used for at least one month, or, depending on the condition, you may need to consult with your doctor. and continue to apply for several months. Apply the medication widely around the affected area. A thin, but not thick, application is sufficient. Wash the affected area daily with soap and water and keep it clean. Try to keep the affected area as dry as possible on a daily basis. If anyone in your family suffers from the same symptoms, please visit a medical institution and receive appropriate treatment. .    Basically, the use of drugs is not recommended. See your doctor individually. The reason why these remedies are necessary is because ringworm is persistent and does not die quickly. You're "cured! If you judge yourself to be inactive, it is simply because the fungus is inactive, and in the case of athlete's foot (ringworm) This is because the stratum corneum layer of the skin is relatively thick, so the fungus often hides and rests in the skin. It may be easy to understand if you imagine "mold" that occurs indoors and other places in your daily life. Mildew is a persistent and repeated occurrence and is not easily killed. It's not difficult to deal with this on your own, so please take a look at it for yourself.   Summary Athlete's Foot and Tapeworm is not a stranger to you. If you're already infected, I hope you know how this feels. The following is a brief description of the process. If you're a carrier, it's not just a matter of if you get infected and develop the disease, it's a matter of if you can be cured. There is none. You are at risk of infecting your loved ones, friends and strangers without any ill effects. I am a typical athlete who has been self-directed and consequently neglected for several years. I may have infected someone else by now. Even that, in the end, we will never know. However, there are patients and carriers of athlete's foot, like me, who are "somehow neglecting" the disease I'm sure you are. I don't want you all to have the same experience that I had. As mentioned above, it usually does not appear as a symptom. There is no way to notice them when they are in a carrier. The rainy season is the time of year when symptoms are most likely to appear. If you are experiencing symptoms that are typical of it (not just the subjective symptoms of athlete's foot, but also the skin changes seen in hives) If you notice any of these things (or any other issues), please see a professional doctor. In that sense, this is the time of year when you have the chance to notice athlete's foot and caterpillar. Have you ever thought about how much contact you have with people and substances each day? You've probably lost count. At all of those times, you may have infected someone else. Or you may be getting a germ. I believe that getting diagnosed and treated as soon as possible will greatly contribute to the prevention of the spread of infection and transmission. The following is a brief description of the process. In addition, the item I was writing about as a coping strategy was, of course, to keep the germ carriers clean. I believe the same is true for non-carriers on the side. Coronavirus is an infectious disease. I know people all over the world are very sensitive to "contact". Athlete's foot and caterpillar are similarly infectious diseases, albeit with different causes and symptoms. Some people think that the symptoms are transient or non-fatal. I think we should abandon that idea right now if Are you neglecting your athlete's foot and caterpillar? Are you applying or stopping medication based on your own judgment? Are you surrounded by people with athlete's foot or ringworm? Once again, this is the time of year to think twice. You will notice that it is most important to not get infected or infected with athlete's foot and caterpillars. Thank you for taking the time to read this far.  

Is it true that high tides (full moon) and high tides are related to childbirth?

Is it true that high tides (full moon) and high tides are related to childbirth?

Weather

"There are more births on the night of the full moon" and "The tide is high, so you might have a baby tonight." Have you ever heard these rumors? Isn't the day of delivery one of the biggest concerns for pregnant women who are expecting a baby? We've been told in advance of our due date, but we don't know if the baby will actually be delivered on that date. It's not. If you're nervous about giving birth on the night of the next full moon or high tide, you're in for a treat! please. .   Does the night of a full moon or high tide result in more births? Does a bovine give birth more on the day of the full moon? According to a study on bovines from the University of Tokyo, the It has been reported that "the number of bovine births increased from the day before the full moon to the night of the full moon. Obstetricians and bovine farmers have long felt that there are more births on full moon days. This was quantified and for the first time the relationship between bovine births and the phases of the moon has been scientifically proven. However, the cause of this change is still unknown. Moreover, the moon's gravitational pull is so small, only 1/300,000 of the earth's, that the bovine really responds to this gravitational change and is able to make it happen. It's not even certain that they are there. What is the response of the bovine to the moon? The results of future research are highly anticipated.   Do countries closer to the equator have higher birth rates at the full moon? The Magic of the Moon, the world's best-selling book by American medical doctor A.L. Lieber According to "The trend for human births is that the number of births is higher on the day of the full moon," according to "The Equator It is more pronounced in countries that are closer to” and The moon orbits the earth, and its orbit is close to the equator, making it "a country close to the equator = a country close to the moon". The increase in births is quite impressive at 10%, but I don't know if it's really true. The debate is still going on.   Does the moon and the tide matter at all? According to a study by Niigata University of Nursing, there was no increase or decrease in the number of births due to atmospheric pressure or monthly age. It has been reported. Although the study only looked at natural childbirths, it only cut out the number of births in some areas. It's also a result. We would like to see more surveys and more data. By the way, one of the interesting things about this study is that even before the study began, "there were a number of different legends based on experience. I am in the process of doing this. Rumors about childbirth everywhere have been around for a long time, and it was a study to determine the truth of the rumors. The Rumors that "there are more births on full moon days" were the impetus for starting such a study. is amazing.   Scientific evidence is not yet sufficient As you can see, there is a lot of research on the relationship between birth and the moon. The results of that study have not yet been scientifically substantiated due to the timing of the study and the lack of a large number of populations. It is inadequate. Childbirth is still an act of mystery.   What is a full moon or high tide? Why do full moons and high tides occur in the first place? Knowing the characteristics of the moon and tides can also help unravel the relationship with childbirth. What is a full moon Why does the moon appear to wax and wane in the first place? The moon itself is not chipped or rounded, is it? The moon appears to be waxing and waning because it is not glowing on its own and reflecting sunlight! . From our point of view on Earth, the moon waxes and wanes depending on where the sunlight hits the moon from in relation to us. I can see it. Therefore, when it looks like a full moon, the sun, the earth, and the moon are aligned, and the moon, which is fully bathed in sunlight, is the earth It's time to capture it head-on from A new moon is a moon that is not visible at all. On a new moon day, the sun, the earth and the moon are aligned with each other. Since the sun is on the opposite side of the full moon, the moon is not visible at all on a new moon day.   Relationship between the gravitational pull of the moon and the tides The moon orbits the earth, because the gravitational pull of the moon and the earth are in balance. It is. It's the same as holding hands with someone and going in circles as fast as you can. If you apply this to the moon and the earth, just as the earth is pulling the moon, the moon is pulling the earth and You are in. The moon is pulling on the earth, so the water on the earth's surface, or seawater, is being pulled by the moon to make it bigger. The tide rises and falls. At this point, the tide rises and falls because the surrounding water also pulls in, creating a "high tide" and "low tide".   High tide is a phenomenon that occurs when the sun and the moon are aligned Why does the tide rise on the day of the full moon? The reason for this has to do with the sun. On nights when the moon is full, the sun, the earth and the moon are in line with each other. In addition to the force of the moon pulling on the earth, the sun also pulls on the earth, so the tide is on both the sun and the moon. The tide will be pulled, and the tide will be higher than usual, and it will be "high tide".   Why is a full moon considered to be a birth Voice from the field The most important reason why many births are said to occur on the night of the full moon is the voice of the birth site. Obstetricians, midwives, and even nurses at the birth site usually say that the number of births increases on the night of the full moon. He feels. As those closest to giving birth believe that there will be more births at the full moon, rumors are increasingly circulating that It seems to have spread. Amniotic fluid being pulled by the full moon? We talked earlier about the relationship between the phases of the moon and the tides, but the composition of amniotic fluid is actually almost identical to that of sea water! . Therefore, some people think that the attraction of the moon may be pulling on the amniotic fluid. . However, this has yet to be scientifically proven.   In modern medical practice, the full moon has nothing to do with childbirth It is said that the number of births increases on the day of the full moon, but in modern medical practice, just because it's a full moon doesn't mean that It doesn't seem to be any easier to give birth. This is because medical advances have made it more common for women to deliver their babies by methods other than natural birth.   Cesarean section and use of accelerated labour drugs In cases where natural childbirth is difficult, a cesarean section is performed and the mother's abdomen is opened to allow the baby to Take it out. A cesarean section is performed on an emergency basis when the mother or baby is not in good shape and cannot deliver naturally. In some cases, the surgery is performed on a pre-determined date. In these cases, it's not just the full moon, it's the birth of the baby. In addition, if it is too late from the expected date of delivery, a labor accelerator may be used. Your obstetrician will decide when you are given the accelerator, so whether the moon is full or not. is irrelevant.   The Mysterious Relationship between the Moon and Women There is a strange connection between the moon and women. Luna Diana Diana Serene Artemis & hellip; these are all goddesses of the moon. Even Princess Kaguya from The Tale of Taketori goes back to the moon, right? Thus, all over the world, the moon has been considered "feminine". What is the relationship between the moon and women?   Menstrual cycles and menstrual cycles are nearly identical A woman's period is called menstruation, and it coincides with the average 29.53 day cycle of the moon's phases It is said that this is the case. Furthermore, the average gestation period from conception to delivery is said to be 265.8 days, which is the month of It is nine times longer than the average cycle of waxing and waning. It has been suggested that the moon has a strong effect on women.   The composition of amniotic fluid is almost the same as that of seawater Amniotic fluid is the water that your baby is wrapped in, which is almost the same as seawater. It is made up of ingredients. The mineral component ratio included is almost identical. The salt concentration is almost the same. And both are slightly alkaline. The gravitational pull of the moon causes the tides to rise and fall. So it is no wonder that the amniotic fluid in mommy's belly is also affected by the attraction of the moon! .   Our story about the birth In addition to the idea that there are more births on a full moon, there are many other rumors about the The truth of these rumors is unknown. I don't know the truth of any of them, but they are all rumors that have been handed down for a long time. Here are some of them.   The day of the full moon is a safe delivery It is said that on the night of the full moon you are more likely to have an easy delivery. The moon's gravitational pull causes tremendous labor pains and the baby is born right away. Sometimes it's hard to deliver a baby due to weak labor pains, so I'm glad if the moon helps you deliver! As far as I'm concerned.   Births are common on typhoon days It is said that births also increase on days of abnormal low pressure, such as typhoons and storms. There was a theory that this is because the pressure is lower, making it easier to give birth, but there was also a theory that it is because it is a typhoon and a different day than usual. Some people have a realistic theory that it may be easier to remember.   Easy to give birth in the morning Natural births that do not involve a cesarean section or other interventions are often delivered between midnight and dawn. Here are some statistics. Specifically, they say that labor starts around 1:00 am to 5:00 am. It's said that contractions start when the parasympathetic nervous system is in control, but relax. and the parasympathetic nervous system is known to be more dominant. When you think about it, if you're always relaxed, you're more likely to give birth, even if it's not in the middle of the night! . The reason why labor is more likely to start when the parasympathetic nervous system is dominant is that in ancient times, predators attacked It is said to be a remnant of a time when it was dangerous. However, the reason for this is not known for certain.   Summary There is a rumor that it is easier to give birth when there is a full moon or high tide, and the number of births actually increases somewhat. It has been reported that the number of births increased. However, it has not yet been firmly established that a full moon equals an increase in births. What about yourself and the people around you, for example? You may be surprised how few people say the full moon is their birthday. No one can predict the date of birth. The day the baby senses that mom is feeling well and wants to get out of the house is the day of his or her birth. It's never a good idea for a mom to be aware that it might be time, but there's no need to be overly tense There is none. Childbirth is a mystical act that only women can experience. Take it easy and wait for the day your baby comes out.

What was the serious damage caused by Typhoon Hagibis and what are the measures to be taken?

Weather

Typhoon No. 19 (East Japan Typhoon 2019), which struck in October 2019, quickly In the Kanto area, in particular, it caused unprecedented damage, with rivers overflowing and levees bursting. Especially in the Kanto area, it caused unprecedented damage, with rivers inundating and levees breaking down. In this section, we would like to look back on the typhoon and discuss what we should do to cope with it. . From the beginning to the end of the typhoon In October 2019, one of the strongest typhoons ever, Typhoon No. 19 will remain strong on the Izu Peninsula. As the typhoon landed on land, its approach and passage caused extensive damage over a wide area from west to east Japan. The typhoon moved slowly over a wide area in Shizuoka Prefecture, the Kanto region and the Tohoku region, causing extensive damage. Became. Now let me explain why this typhoon has become a super typhoon compared to other years. The main reason is believed to be global warming. The following two factors are believed to be responsible for the super typhoon.   (1) Global warming is warming not only the surface of the ocean but also the deep sea  (2) Global warming is slowing down the speed of typhoons Regarding (1), due to the effects of global warming, not only the surface of the sea, but also the deep sea will be warmed up and the ocean heat will be The increase in the number of typhoons each year is a growing problem. Ocean heat acts like fuel for tropical cyclones, and as a result, typhoons are getting stronger and stronger every year. It is believed that there are Regarding (2), between 1946 and 2016, the rate of movement of tropical cyclones was 10% globally. The global slowdown in summer atmospheric circulation, due to global warming, has been a major factor in the The company says the typhoon is slowing down its speed of movement. For this reason, Typhoon 19, which was confirmed on October 9, has increased its strength, and on October 12 It made landfall on the Izu Peninsula just before 19:00 p.m. Between October 10 and 13, it caused heavy rainfall in eastern Japan. It became a temperate cyclone at midnight on October 13 and then disappeared.   Overview of the Damage Caused by Typhoon No. 19

What kind of disease is heat stroke? Here's what to do about it, and how to prevent it!

Weather

Heat stroke definitely shows up in the summer months. Heat stroke occurs every year, but this year the number of cases is expected to increase even more due to masks! And…. . We will discuss heat stroke, which occurs not only in humans but also in pets such as dogs and cats.   What is heat stroke? Our bodies unconsciously maintain a constant internal temperature to allow our bodies to function normally. We try to be able to do this. However, if you stay in a hot place for a long time or are exposed to the sun for a long time under the hot sun, your body's temperature regulation is not You can't do it well and your body temperature rises. This leads to poor blood circulation, an imbalance of water and salt in the body, dizziness and cramps. This is called "heat stroke". This is called heat stroke. It's a very good way to get rid of the problem. . and degree I Grade I is a mild disease that can be treated with first aid only on the spot when it occurs. Symptoms include dizziness, muscle pain, stiffness of muscles such as tossing and turning, and profuse sweating. The following is a list of the most important information and Grade II Degree II is one that requires transport to a hospital that cannot be dealt with on the spot alone. It's a very good idea to have a good idea of what you're doing. . and degree III Grade III is a serious condition that requires hospitalization and intensive care. Symptoms include loss of consciousness, convulsions, loss of movement in the hands and feet, and high body temperature. .   Where is heat stroke most likely to occur? The image that comes to mind as heat stroke is: "You're exercising for long periods of time under the hot sun in the middle of summer, and you're drinking water on top of You may be in a state of "I didn't take it". For example, in the rainy season, when the temperature suddenly rises, you may feel hot. The reason for this is that they are not accustomed to the heat. In addition, it can also occur on days with high temperatures and high humidity, when the sun is strong but the wind is weak, and when tiles and other tiles are exposed to strong reflections. You may also be at risk of developing the disease. It's especially easy to get caught off guard on days when the temperature is low but the humidity is high. It is important to keep in mind not only the temperature, but also the humidity. . Also, the evil hand of heat stroke extends not only to the outside but also to the inside of the house. Don't be reassured just because you are at home, but also make sure you are properly hydrated.   Preventing and preventing heat stroke So what can you actually do to prevent and counteract heat stroke? The first is to review your clothing from the material you're wearing. It goes without saying that long sleeves and long pants are a high risk for heat stroke, but even if you have short sleeves, the fabric The breathability and heat absorption rate will vary depending on the material. Recommended materials with good ventilation and low heat absorption are linen and cotton. As for the design, choose the one with an open collar and sleeves so that the heat does not stay in easily, and wear an inner layer inside to keep the heat in from the outside. It is recommended that you don't let the heat attack your skin directly. The second thing you need to do is to hydrate frequently. We are often told to drink before we feel thirsty in hydration, but you never know when the temperature is high. In the course of time, you may be sweating and the amount of water in your body may be lower than you imagined. The drink I recommend at this time is mineral water and other drinks that provide water and minerals and vitamins! However, since sports drinks contain a lot of sugar, it is important not to drink too much water with them. You can try to increase it. On the other hand, what you should not drink are diuretic coffee, green tea, and alcohol. It's a very good idea to take care of your drinks on a hot day so that the water you put in doesn't go out. . And the third is to avoid the heat. It's important in preventing heat stroke, but we need to keep the sun out of our homes by wearing a drape in the house. Even if you use a fan or an air conditioner, you can't stop going outside completely. If the environment is not as cool as indoors, use a parasol or a prevention device to avoid exposure to sunlight. , try to walk in the shade as much as possible. Finally, the fourth and final step is to make your body resistant to the heat. While it is certainly important to take various measures and implement them, the effectiveness of these measures will vary from person to person. In order to reduce the differences between individuals and get the effect of the countermeasures, it is necessary to have a body that can withstand the heat. You should make a habit of doing some kind of exercise such as walking or running on a regular basis to work up a sweat, even under hot conditions. I will remake my body to be able to cope. The first three can be done at any time and the effect is obtained, but the fourth one takes time and does not have immediate effect. I do not. However, the time to fight heat stroke comes around every year. It's a good idea to start now and aim for next summer, or even this summer if you can.   Summary Because of the large number of cases of heat stroke every year, many people may not be too concerned about it as a "common" disease It may be, but in some cases it is a life-or-death disease. This is true not only for people, but also for dogs and cats. If you have pets, try to buy goods to prevent heat stroke, or use the above measures for people. But I say, take precautions to beat the heat!

How a rainy season front develops and how it works

Weather

How the rainy season front We would like to introduce the mechanism and nature of how it works and whether it does.   What is a rainy season front The rainy season front How it occurs A rainy season front is a kind of stagnation front So a rainy season front is formed when warm air and cold air collide. A rainy season front is a kind of stagnation front, so when warm air and cold air collide, a rainy season front is formed. It is a stagnant front that is active over Japan from early May to early August, and although its speed is slow, it takes time to move northward. Although its speed is slow, it takes time to move northward. It disappears in the southern part of Hokkaido. It is relatively mild and the rainy season is long. Another feature of the rainy season front is that it is more active before it disappears than when it first appears. We have a tendency to do this.   On the nature of the rainy season front The air masses that create the rainy season front The momentum is competitive and very unstable. Basically, the rain is not strong. However, as typhoons and canyons move in, the movement of the front becomes more active, and strong rain clouds, including thunderclouds, are formed. If the balance between the two antagonists is stable, it may result in the formation of an ice storm or heavy rainfall. Rainy season fronts rarely move. When a low pressure system approaches, or when it is out of balance, the front changes temporarily to a warm front or a cold front. The following is a list of the most important information   Similar Different Autumn Rain Front in Different Autumn Rain Front Autumn rain front is from late August to October It is a stagnation front that is said to develop in Japan in the second half of the year. This is a stagnation front. The stagnation front pushed northward by the increasing momentum of the Ogasawara air masses in summer is called the stagnation front. As it wanes, it dips to the south and disappears off the southeast coast of Japan around the end of October. It is the opposite of a rainy season front, which is active at first but wanes in the latter half of the year.   What type of air mass is it? What impact will it have? Okhotsk Sea Air Group Okhotsk Sea Air Mass is a rainy season front and It is one of the air masses that is largely responsible for the development of the autumn rain front. It is a cold-zone oceanic air mass with moist, cold air from the Okhotsk Sea and the coast of Sanriku, and the Okhotsk Sea air The development and activation of the group is also a cause of the rainy season and other factors.   Ogasawara Kidan The hot and humid summer is the main cause of This is the Ogasawara Air Group. The warm, humid breeze from the south clumps into a mass of air in the summer. It develops in tropical marine air masses.   Equatorial Air Group Equator, which is somewhat far from Japan A warm and moist air mass in the vicinity is called an equatorial air mass. In summer, a tropical cyclone develops and brings it over Japan.   Frontline Basics 2 Two different air masses The boundary plane that collides and touches each other is called the frontal plane, and the part that touches it is called the In the case of a front, it is called a front. An air mass that is a mass of cold air is called cold air, and a warm air mass is called warm air. Two types of fronts, such as a cold front and a warm front, are said to occur depending on how the two collide. . When a front occurs, the area approaching the front is bad weather. There is a big difference in terms of how the weather becomes worse and what happens after the front passes, etc. The following is a list of the most important information   There are many other types of fronts There is Autumn Rain Front Autumn rain front is a front whose season is from summer to autumn. It appears around the turn of the season, and may start to appear as early as late August. The Pacific High, which generates hot weather, weakens and the Okhotsk Sea Pressure approaches Japan, causing summer heat. and the cool autumn air collide, which creates an autumn rain front.   Warm front Warm front has warm air mass It is caused by contact with a cold air mass, such as a cold front, as it moves through. When a warm front passes through, the temperature rises gradually and turbulent clouds develop. Weak rain falls for some period of time and becomes more active as warm air flows from the East China Sea to the warm front. The likelihood is greater, and severe thunderstorms can occur, such as when a cold front passes through.   Cold Front When a cold front passes For a short period of time, it will become torrential rain and after it passes, the temperature will drop. It won't last long, but thunderstorms and wind gusts are possible in a short period of time. If the temperature difference is large, tornadoes are likely to occur.   Closing Front Warming front from a temperate low and The cold front is faster and larger than the cold front, so the cold front is closer to the center of the low pressure system and catches up with the warm front and becomes a blockage front. If there is a slight temperature difference between the cold air in front of the warm front and the cold air behind the cold front, and air-to-air contact A low pressure system with a blockage front because the warm cold air above is going up, and the low pressure system with a blockage front means that the warm air is pushed up into the sky. It is weakened by   Stagnation Front The momentum of the warm and cold air masses This is a front that occurs when the two fronts are in contact with each other at the same level or in a state of motion. A stagnant front is formed when the wind direction and direction of the front are equal. It becomes more active when warm air flows in from over the South Sea, which can lead to large cumulus clouds and heavy rainfall. There seems to be.   Summary The rainy season front and two air masses A rainy season front occurs when they collide and compete with each other. Basically, the weather is not violently disrupted, but in some cases, torrential rains and cumulus clouds occur. It seems to be a possibility.

For those of you with frizzy hair that's suffering from the humidity of the rainy season, I suggest you straighten your hair!

Weather

During rainy days, rainy season, and other humid times of the year, hair can spread out and there are floating and stupid hairs everywhere. The problem is the unmanageable swelling and dryness that can occur. It is often said that frizzy hair is more susceptible to the effects of moisture, especially on frizzy hair, but the truth is that we usually don't color our hair. If you have a ring and iron your hair, you can get a ring because your hair is sore. It's getting cheaper ….   Why does humidity stop my hair from listening to me? The structure of the hair is the cause of the changes in the hair caused by moisture. Each human hair is thin, but the center of the human hair is called a medulla, like a seaweed roll. The hair is wrapped with something called cortices, and the cuticle protects the outside of the hair in addition. When the hair is damaged, the cuticle peels off and the cortices inside come off. It will get out. When the contents flow out and get scuffed up, dryness, split ends, and breakage can occur, but in rainy or humid weather On days when there is a lot of moisture in the pores there, it gets into the holes there. This causes a significant increase in the amount of moisture in the hair, which is usually about 11-14%, and causes the hair to spread out, become clumpy, and This will cause a situation where there is no As you can see, humidity can be a problem even for people with non-habitual hair, but it's even more difficult for people with frizzy hair. If you have frizzy hair, even a single strand of hair is made up of a mixture of dry and marshy areas. Even though the internal moisture content of the hair is not evenly distributed, on rainy days or during humid periods, the hair retains moisture. This leads to further swelling. This can lead to uncontrollable, breakage and frizzy hair.   Hair straightening is the best way to deal with dampness on hair⁉︎ There are several ways to prevent your hair from being damaged by moisture. Straighten your hair Make your hair less frizzy Use of styling products Change your shampoo or treatment The quickest and quickest of the four is hair straightening.

Even if it is for a lifetime, hair grows every day, so treatment to the growth is necessary. The secret to the effectiveness of hair straightening for frizzy hair during humid times is the function of the hair. The hair of people with frizzy hair has a weaker ability to retain the moisture it needs on its own than those who don't, and therefore It looks sore, and even if you get up early and blow-dry or iron your hair to counteract it, your hair will still have excess from the air.

Details of the rainy season, the rainy season in each region, and tips on how to view a weather map.   What is the rainy season? The rainy season is the rainy season in Japan. The rainy season begins in May in the early areas as an average period and ends around June in most areas. However, with the exception of Hokkaido and the Ogasawara Islands, there is no rainy season. Basically, the end of the rainy season comes in June or late July. The final rainy season in September of each year is taken as a definite value, but if the onset or end of the rainy season is taken as a preliminary value, the period seems to take place. In some cases, this may be done without specifying. During the rainy season, the two forces of the Ogasawara Air Force and the Okhotsk Air Force clashed, causing the weather to be sluggish and uneventful.   About the etymology of the rainy season

Summer masks, beware of heatstroke! Hydrate a little!

Summer masks, beware of heatstroke! Hydrate a little!

Weather

The hot summer is already here this year. However, there is one thing that is different from previous years, and that is that everyone wears a mask. The director of the Center for Advanced Emergency Medicine at Teikyo University Hospital pointed out that "we are about to enter a summer that has never been experienced before by the entire human race where many people wear masks in the summer". If you are accustomed to it, you can get through the summer without a problem, but not so much if you are unfamiliar with it. One of the harms is heatstroke. This is the most important thing to be aware of, but when it comes to wearing a mask in the summer when it can occur even if you're not wearing a mask, it's harder than ever to avoid heatstroke.   Why does wearing a mask increase the risk of heatstroke? As to why wearing a mask increases the risk of heat stroke, the Ministry of the Environment says, "Wearing a mask increases the heart rate and respiratory rate. It puts a strain on the body and increases the risk of heatstroke. When heat builds up in the body, not only in the summer, but also when the temperature rises, we regulate our body temperature by sweating and taking in cold air by breathing in order to dissipate and eliminate it. However, if you wear a mask, the air you take in by breathing in will be your own exhalation, so instead of serving the purpose of cooling your body, it will help your body temperature to rise. On top of that, since nearly half of the face is covered, it is easy for heat to build up inside, making it even harder to dissipate heat. In addition, masks have a humidifying effect, which may give the illusion that you are taking in water, making it difficult to feel thirsty. In addition to having to wear masks, the Japan Meteorological Agency (JMA) has announced that this year's temperatures will be as hot as or hotter than normal, and it is expected that this summer, when people live with masks, it will be hard to notice that they are suffering from heat stroke, and many of them will be in a dangerous condition before they realize it. In this summer, we are forced to live in hot temperatures and not be able to leave our masks, but what is frightening is the increase in the number of medical facility punctures and nosocomial infections due to the increase in emergency transport of heat stroke patients. However, in 2018, when it was extremely hot, about 95,000 people were transported to the hospital in about five months due to heat stroke, and if the same or more people were transported, it would be extremely difficult to prevent. So how can you spend your summer?   How can I prevent heatstroke while wearing a mask? It's the same when you're wearing a mask but not doing basic protection. First of all, hydrate frequently, whether you are thirsty or not. It's not often that you have a drink when you're not thirsty in your daily life, but if you wear a mask, it's even harder to notice your thirst, so don't forget to do it. At this time, it is difficult for your body to absorb the water if you sip it vigorously, so drink it slowly. Don't forget to give fluids not only to adults, but also to the elderly, who are less likely to feel thirsty, and to children, who are less likely to notice and complain of thirst. The next step is to control and adjust the room temperature. In addition to ventilating by opening windows and turning on the ventilation fan, be sure to use the air conditioning. In this period of self-restraint, it is difficult to devalue assets, but what is more important than anything else is life. Make sure your home is cool. And finally, a story about being on the go. Have you ever worn a mask and felt annoyed by the sweat and shortness of breath when exercising outside? On the other hand, I worry about taking off my mask because I want to take a break. Some of you may think so. The best thing to do on a hot day is not to go to a populated place and not to go out, but that's not the case. Regarding the wearing of masks outside, Environment Minister Shinjiro Koizumi told a press conference after a cabinet meeting on March 26, "There is no message that it is safe to remove masks at any time, but there are cases where removing masks is not a problem as long as the environment is sealed, dense, and close, and the risk is taken into account. Therefore, if you are experiencing heatstroke symptoms such as suffering from heat or dizziness while you are out, take a break in a deserted area and take off your mask once to catch your breath. Of course, please take a good amount of water at this time and take a proper rest.   Recap It's going to be a summer that feels hotter than the temperature for the majority of people, but let's get through it together!

When it rains and is humid and humid, you can't even hang your laundry out to dry every day during the rainy season.   In Okinawa, the end of the rainy season was announced early, and it was the seventh earliest since the statistics started in 1951, and the end of the rainy season was 28 days earlier than last year. It was expected that the rainy season would end soon in Amami region as well, but it did not end easily and the latest in Amami region was July 15, 1983, and the end of the rainy season was finally announced on July 20, 1983, which was 7 days later than last year and 21 days later than the normal year. The record has been broken.   Around the end of June, the beginning of the rainy season was predicted to be near, except for some places, but then there were many places that suffered from the record-breaking downpour. In the torrential rains in July 2020, the total rainfall exceeded 1,000 mm in many places and caused extensive damage. Since then, there have been many places where the total rainfall exceeded 1,000 mm, causing extensive damage.   Finally, the rainy season front has started to move up north and there is a high possibility that the rainy season will end in Kyushu and Tokai later in the week. It's a good thing that we're not just talking about a few of the most popular things in the world.   In Kanto Koshin, Hokuriku and Tohoku regions, the uncluttered weather is likely to continue for a while yet, and the end of the rainy season is expected to be after early August. It is also a good idea to check out the latest information on the latest weather conditions, such as landslides, flooding and river flooding.   This year's rainy season is lingering, but if the number of typhoons in July remains at zero and continues, it will be the first time in recorded history that the number of typhoons is still zero. The number of typhoons this year has been only two until June, and the average number of typhoons by July is around seven, so if this trend continues, this will be the first time in recorded history that the typhoon has occurred.   After the end of the rainy season, since the heat tends to continue to be relatively severe, it is also the time when the number of people suffering from heat stroke increases rapidly, so let's avoid the heat by using fans and air conditioners in moderation and try to hydrate frequently.   More people feel unwell during the rainy season due to the change in atmospheric pressure and the large difference in temperature between the cold and the hot season, which causes headaches and fatigue. It's also the change of seasons, so please take care of your health condition.   Although Japan is a small country compared to other countries, the start and end of the rainy season varies from region to region and we will tell you about the start and end of the rainy season across the country in 2020.   What are the effects of the rainy season on your health, including headaches and poor health due to changes in atmospheric pressure?   The start of the 2020 rainy season Updated July 20, 2020 Region 2022 Normal Year Last year Okinawa around May 11 around May 9 around May 16 Amami around May 10 around May 11 around May 14 Southern Kyushu around May 30 around May 31 around May 31 Northern Kyushu around June 11 around June 5 around June 26 Shikoku around May 31 around June 5 around June 26 China around June 10 around June 7 around June 26 Kinki around June 10 around June 7 around June 27 East Sea around June 10 around June 8 around June 7 Kanto Koshin around June 11 around June 8 around June 7 Hokuriku around June 11 around June 12 around June 7 Southern Northeast around June 11 around June 12 around June 7 Northern Tohoku around June 14 around June 14 around June 15 ※From the JMA website End of the rainy season in 2020 Region 2022 Normal Year Last year Okinawa around June 12 around June 23 around July 10 Amami around July 20 around June 29 around July 13 Southern Kyushu   around July 14 around July 24 Northern Kyushu   around July 19 around July 25 Shikoku   around July 18 around July 25 China   around July 21 around July 25 Kinki   around July 21 around July 24 East Sea   around July 21 around July 24 Kanto Koshin   around July 21 around July 24 Hokuriku   around July 24 around July 24 Southern Northeast   around July 25 around July 25 Northern Tohoku   around July 28 around July 31 ※From the JMA website       What is the rainy season front? A brief explanation of how it occurs and how it works   What is the rainy season? Let's review a little about what the rainy season is all about in the first place. The rainy season is not found all over the world, but it is a unique weather phenomenon with frequent cloudy and rainy weather that occurs in East Asia (southern China to the Yangtze River basin, Taiwan, and Japan, except for Hokkaido and the Ogasawara Islands). It occurs mainly between May and July. Incidentally, why is it called "the rainy season"? There are many theories about the origin of the word "plum rain", such as that it is the time when the plum seeds ripen, or that it was called "moldy rain" because it is a time when mold tends to grow due to high humidity, and so the word "plum rain" was used.   How to prepare for the rainy season by remembering the weather map   Rainy Season 2020 Overview The beginning of the rainy season in Tohoku The start of the rainy season in the northern northeast was June 15 in 2019, and June 14 in the normal year, as usual. In the southern northeast and Hokuriku, the start of the rainy season was nearly a week later than last year's, with June 12 in 2019 and June 7 in the normal year. In fiscal year 2020, the rainy season in the southern Tohoku region started 4 days later than last year, or 1 day earlier in the northern Tohoku region. The beginning of the rainy season in Kanto Koshin and Tokai regions The start of the rainy season in the Kanto Koshin and Tokai regions was June 7, 2019, and June 8, 2019, almost as usual for a normal year. In 2020, the rainy season will begin 2 to 3 days later than last year. Western Japan at the beginning of the rainy season(Kinki, Chugoku, Shikoku, Northern Kyushu, Southern Kyushu)Which national weather station announces the start or end of the rainy season? Tohoku Region: Sendai District Meteorological Office Kanto Region: Tokyo Regional Meteorological Observatory Hokuriku Region: Niigata Regional Meteorological Station Tokai Region: Nagoya Regional Meteorological Station Kinki Region: Osaka District Meteorological Office Chugoku Region: Hiroshima District Meteorological Station Shikoku Region: Takamatsu Regional Meteorological Station Northern Kyushu: Fukuoka District Meteorological Observatory Southern Kyushu: Kagoshima District Meteorological Station Okinawa Region: Okinawa Meteorological Station   Summary With some areas experiencing record-breaking downpours for the first time in recorded history, weather is a major factor in many people's lives, but it is extremely difficult to know it perfectly. To begin with, the rainy season is not a time to declare "the rainy season starts on this day" but rather a very ambiguous one, and the rainy season is a time when many unpredictable, heavy rainfall-related disasters occur.

What is high tide?

Weather

Waves are also one of the most important factors in surfing, as the words "high tide" and "low tide" refer to. It is important to know how the tide is coming and going, especially if you want to ride a good wave and improve quickly. Here, let's look at the high tide. What is high tide? If you look at it casually, you won't notice much, but the sea level goes up and down almost twice a dayevery day. The height of the sea level is always changing slightly. If the tides rise and fall twice a day, it takes about six to seven hours for the water level (tide level) to fall from the highest to the lowest, and then it takes another six to seven hours for the water level to rise from the lowest to the highest. In addition, it is also possible to make use of the new technology to improve the quality of your life. It is there. On the other hand, when the water level is at its lowest point, it is called "low tide".   How the high tide works Many people know that the tide goes in and out, but how does it go in and out again? Here's how the high tide works. The relationship with the moon plays a big part in the ebb and flow of the tide. The Moon revolves around the Earth in an orbit of about 27.3 days. As can be seen by the law of universal gravitation, all objects in this universe have a gravitational pull. This is also true of the moon, which also has a gravitational pull. The seawater in the ocean is liquid, so it can move freely and change its shape. Therefore, on the side of the sea facing the moon, the pull of the moon lifts the surface of the sea, and the tide is high. This attraction works not only on the sea surface facing the moon, but also on the sea surface facing and opposing the moon. For this reason, it is high tide, both on the side facing the moon and on the other side of it. Then, the middle part between the side facing the moon at high tide and the other side of the moon is at low tide.   How much is the difference between high and low tide? For those of you who enjoy surfing and other sea activities, the difference between high and low tide may be a concern. The actual difference between high and low tide varies greatly from place to place as well. In Japan, the difference between high tide and low tide in the Sea of Japan is about 40cm, so the sea level does not change that much. On the other hand, on the Pacific side, the difference between high and low tide is about 1.5 meters, which is an extra 1 meter compared to the Japan Sea side. Outside of Japan, the difference in tide can be as much as 10 meters in Incheon, South Korea, and 15 meters in Mont Saint-Michel, France. And the world's highest tide difference between high and low tide is in the Bay of Fundy in eastern Canada. In the Bay of Fundy, there is a tide difference of up to 16m. The tide has eroded the cliffs and exposed fossils, so it's a great spot for surfers and your family and friends to enjoy.   Don't judge a surfing newbie by the tide alone! Looking at the difference in tide level, some people may think that the Japan Sea side is gentler than the Pacific side, so be careful. When surfing or playing in the sea, it is important to take into account not only the tide level but also the influence of the wind. On the Japan Sea side, the sea tends to be rough from late August to April due to the north wind, so even if the tide is low, it is not recommended for beginner surfers. On the other hand, from May until around Obon, the winds blow from the south, so the Sea of Japan side is relatively calm. The Pacific Ocean side is the opposite of the Sea of Japan side, with calm seas from late August to April, and rough seas from May to around Obon. Therefore, if you are a surfing beginner, it is recommended to practice from spring to Obon on the Sea of Japan side, from Obon to winter on the Pacific side.   High tide is not good for surfing If you are a beginner or not familiar with the waves, you may think that the sea level is higher at high tide, which is a good time to surf. However, high tide is not a good time to surf. When surfing conditions are dangerously high, you don't want to have dangerously high waves, but you don't want to have any waves at all or have no waves at all. The waves are good for surfing when the tide is moderately high, called the low (ebb) or high (pot) tide. Ebb tide is literally the state of the sea level as it drops from high tide to low tide, while ebb tide is when the sea level rises from low tide to high tide. At this time, the amount of seawater gradually changes over a long period of time, which is difficult for us humans to notice, and the sea level moves along with it. In fact, without this kind of sea level movement, there would be no waves. Therefore, it is not suitable for surfing at high or low tide when the sea level does not change. In addition, beginners are more comfortable and easy to practice in the calm sea, but it is also not suitable for surfing if there is no change in the sea level, such as no wind. It is necessary to check the high and low tide time the day before you go surfing, but if the high and low tide come up during surfing or the wind is gone, it is a good idea to take a break until the sea level changes.

Sickness Affected by Weather 'I thought my head hurt and then it rained the next day,' or 'I'm not feeling well during the rainy season and can't do anything about it,' Many of you may have had the experience of getting sick on a rainy day or before the weather breaks, such as "when it rains, my old wounds hurt. You may be thinking, "Maybe it's just a coincidence that I'm getting tired," or "Maybe it's just my imagination," but did you know that it's not your imagination? Poor physical condition caused by such weather changes is called "weather disease" or "weather pain". People who suffer from this weather disease or weather pain are more likely to be women in their 20s and 40s who are more susceptible to female hormones It is said that. Low pressure in the shadow of poor performance But here's a little something that stuck with me. It's called a "weather disease," and while some people get headaches or get sick before the weather breaks, you don't often hear of people getting sick before the weather recovers. In addition, some people who get sick because of the weather have a headache or get sick if it's raining normally, but when it's before a guerrilla downpour or a typhoon, they can't help but take their medication. Some people have severe headaches and can't stay awake. The reason why such a mysterious phenomenon occurs is that human health and low pressure have a big influence on it.   The workings of the autonomic nervous system and dysregulation Normally, if you're in good health, you won't get sick when the temperature and weather change. This is because we have the ability to maintain a constant state of the body even when the environment surrounding us, such as temperature and weather, changes. It is thanks to the "autonomic nerves" that the body is able to keep itself in a constant state. The autonomic nerve is a nerve that is in charge of life support activities such as the circulatory, digestive and respiratory systems in the human body, and it works 24 hours a day even when we are unconscious, such as while sleeping. When the autonomic nervous system is out of balance, the body becomes sluggish, headaches, shortness of breath, diarrhea, constipation, and various other ailments appear. If this condition becomes severe, it becomes a disease called "autonomic dysautonomia".   Low pressure + autonomic disturbance causes poor physical condition

What is a low pressure and what is a high pressure? About the change in weather

Weather

When you're planning a weekend of surfing or a family trip to the beach, you're probably concerned about the weather forecast. If you watch the weather forecast on TV, you may hear the weatherman say "low pressure will develop over the weekend" or "high pressure will develop". There are vague images of "low pressure = bad weather" and "high pressure = better weather". However, I think there are not many people who know about low pressure and high pressure in detail, so I will introduce low pressure and high pressure here. What is a low pressure? The "barometric pressure" of a low or high pressure is the pressure of a gas and generally refers to the pressure of the atmosphere. When the pressure is low, it is called a low pressure, but there is no standard for a low pressure below 0 hPa. Low pressure is relative, when it is low compared to the surrounding pressure It is called a low pressure. The air is thinner than its surroundings in the "low" part of the region where the pressure is lower than its surroundings. The air is denser in the higher pressure areas around the low compared to the low. Therefore, the air in the high pressure area, where the air is dense, will move towards the low pressure area, where the air is thin. This causes the wind to blow towards the low pressure. That way, after the air that flowed in collided with each other, the only place to escape was up and down and down. The upward wind (updraft) is generated because of the ground. In the air, there is originally a lot of water vapor, and this water vapor goes up into the sky on the updraft. Since there is cold air in the sky above, the water vapor on the updrafts is cooled down to form water droplets and ice, and the grains of these water droplets are called clouds. These water droplets and grains of ice collide with each other and become large and heavy, so they cannot float in the air and fall as rain or snow. This is why, when there is a low pressure on the weather map, it becomes cloudy at the center of it, or rain or snow falls and causes the weather to break down.     What is a high pressure? The high pressure causes the exact opposite of the low pressure. The air is denser in the "hyperbaric" areas where the pressure is lower than the surrounding area. The low air pressure areas around high pressure are thin compared to high pressure. Therefore, air is blown out to take air from the high pressure area to the low pressure area. When that happens, there is no air in the high pressure area, so air comes down from above to take in air. Therefore, when there is a high pressure, even if there are clouds in the sky above, they will be scattered into the air by the downward wind. Therefore, when a high pressure system arrives, the clouds above will disappear and the weather will clear up and improve.   Why does the low pressure occur? Low pressure is a place where the air is thinner than the surrounding area, which may raise the question of why such a place is created. During the day, when the sun is out, its light hits the ground. However, in doing so, for some reason The sun's rays don't hit the ground evenly, and only one area of the ground may be heated and have heat. This is when the low pressure occurs. This is because when the ground warms up, the air above it also warms up. Warmed air rises because it has the propensity to go up. That way, the area where the air has risen will have less air, so air will move in from around it, creating a low pressure.   Front related to rainfall At first glance, it looks like a low pressure = bad weather = low temperature, but a low pressure is a collection of warm air. This boundary between warm and thin air and normal air is called the front. If there is a low pressure in the middle, it will be in the form of a front on the right and a front on the left, but these two fronts are very different in nature. The front on the right in the figure below is called a "warm front" because when it passes through this front, it is taken into the warm air of a low pressure and the air temperature rises. On the other hand, if a front on the left passes through while in a warm low pressure, it will be thrown out into the normal air and the temperature will drop, so it is called a cold front. In the case of a warm front, warm air flows into the cold air, but the warm air is so warm that it slides over the cold air as it rises. On the contrary, cold fronts allow cold air to flow into warm air. The cold, chilly air is heavy compared to the warm air, so it slides down. In fact, this difference can make a big difference in the weather. In the case of a warm front, the air moves gently and water vapor evaporates along the air, forming clouds. On the other hand, a cold front is characterized by the fact that the boundary between cold and warm air is steep and clouds tend to gather in one place. Depending on these characteristics, there are different types of clouds. Clouds formed in a warm front tend to form stratospheric clouds, while those in a cold front tend to form cumulonimbus clouds. As a result, there will be strong showers and cooler temperatures under a cold front. On the other hand, when a warm front passes through, there is a long period of moderate rain and the temperature rises. So, before you go out to surf or go to the beach, make sure that a cold front does not pass through.

Typhoon measures and basic knowledge to hold down

Weather

If you want to enjoy marine sports such as surfing, it is important to keep yourself safe. Especially in the case of typhoons, strong winds and high waves have a great impact on the sea, so it is important to think about how to prepare for typhoons. The importance of countermeasures for each type of typhoon damage Unlike natural disasters such as earthquakes that strike without warning, typhoons are natural disasters that can be predicted to a certain extent in advance, so it is necessary to take precautions in advance. If you live in Japan, you have been experiencing typhoons many times since you were a child. It is important to take appropriate measures for the type of damage. The damage from the typhoon was mainly ・gale ・Rain and heavy rain ・Landslides ・Storm surge There are four types of products. Of these, let's consider typhoon countermeasures for common storms and torrential rains and typhoon countermeasures near the sea.   Storm Control Of the four, the one that has the most widespread impact is the storm. In the case of wind typhoons, etc. Storms and gusts of wind can cause massive damage in an instant. Especially in the case of wind storms, flying debris picked up by the wind can cause damage such as hitting window glass or flying roofing materials, and injuries from flying debris can be considered. Eliminate flying objects. Therefore, as a countermeasure for storms before a typhoon, it is possible to remove anything that may be scattered from around the building, such as the home. Plant pots, clothes poles, bicycles, etc. that are outdoors should be taken into the building. If you can't take it indoors, secure it with a string to prevent it from flying away. Protect your windows One of the most common types of damage during a typhoon is when objects scattered in the storm hit the window glass and break it. The most effective way to prevent such damage is to tighten the shutters and shutters on the windows. If you don't have a storm door or shutters, hold a board or cardboard against the window glass and secure it with curing tape. This way, not only does the board or cardboard act as a cushioning material and make it harder to break, but it also prevents the glass from flying off in the event of a break. What's more, a broken window can not only cause rain to shake in, but it can also cause the roof to be lifted and blown away by the storm winds blowing in through the broken window. This kind of damage can also be prevented by reinforcing it with boards or cardboard. Especially in areas near the sea, the wind from the sea tends to be strong, so it is important to take appropriate measures.   Rain Protection There is a type of typhoon called a rain typhoon. The biggest problem in a rainy typhoon is that roads and buildings are flooded. As a countermeasure, remove leaves and debris clogging gutters and gutters that serve as rain flow paths. It's easy to forget, but if a heavy downpour falls in a short period of time, the sewer system can't handle it all It can back up and run down the drain into the room. If you hear a rumbling sound, especially in the toilet, bathroom or washroom, you need to be careful. If you're worried about flooding in a heavy rainstorm, cover the drains with a plastic bag filled with water, for example.   Keep an eye on the path of the typhoon If you've had a typhoon in the far south of Japan, but plan to go to the beach soon, you'll want to be sure to keep your eyes open. It's important to know the path of the typhoon. Even in areas away from the typhoon, the wind and waves could have an impact, depending on the path and direction of the typhoon There is. However, if the predicted path to the area where you are or will be going, you may not even know if a typhoon is coming or not. If this is the case, you should prepare yourself to some extent before you go out to sea by anticipating your route. ◆Typical paths by time of year Typhoons occurring in the southern part of Japan have a different path depending on the time of year and the main path that we know from the statistics so far. Typhoons that occur between July and October, when the most typhoons enter Japan, tend to curve to the east. The other months of June and November/December tend to move westward and away from Japan. In particular, from July to August, the route from Kyushu northward to the Sea of Japan, from the Kii Peninsula and Tokai to Kanto in September, and from east to west over the southern ocean without approaching the Japanese Islands in October There is a lot of progress to be made. ◆ Check the position of the high pressure One of the characteristics of a typhoon is that it follows the high pressure and goes around. When a typhoon arrives near the Japanese Islands, if there is a high pressure on the weather map near Japan, it will move from west to east with westerly winds following the high pressure in most cases.   If this happens, don't go anywhere near the ocean One of the most common questions asked during the typhoon season at dive shops offering ocean activities is, "There is a typhoon approaching, is it going to be canceled? I can only say that the answer to this depends on the type of activity and the circumstances. Diving, kayaking, and glass boating will be cancelled as early as the waves start to come out, as small children may be involved. On the other hand, surfers may find it more fun to have a few waves. However, there is no point in getting injured or losing your life. Depending on your experience and skill, there is a difference in when you should stop surfing. However, if a surfing competition is cancelled or a surfing spot is closed out, stay away from the ocean as the danger is just around the corner. In addition, beginners and those who are not good at swimming should not enter the sea if the waves are higher than the waist, if the typhoon is approaching, because it will be dangerous.

What is a typhoon? For those who enjoy marine sports such as surfing, wakeboarding, and diving, the weather is as important as the information on the waves. Among them, it is especially important to pay attention to typhoons. Typhoons come to Japan from the end of summer to autumn and have become a seasonal phenomenon, but the question "What is a typhoon? Let's take a look at typhoons, because many people don't understand the meaning of the word "typhoon". According to the JMA's definition, a tropical depression that occurs over the ocean in the tropics and is located in the Northwest Pacific or South China Sea and has an average maximum wind speed of 17 m/s for 10 minutes and a wind speed of 8 (tree branches are broken or it is difficult to stand) is called a "typhoon.   How do typhoons come into being? In autumn, typhoons suddenly appear on the weather map one day, but there is a mechanism by which they form. As the seawater temperature rises, the seawater evaporates as water vapor. In doing so, water vapor is lighter than air, so it creates an updraft. When an updraft is created, the air pressure drops and it becomes a state called a low pressure. A normal low pressure can be formed in the Japanese Islands, but a tropical depression, which becomes the base of a typhoon, is formed in the tropics. The water vapor evaporated from the sea surface is cooled in the sky above and becomes a cumulonimbus cloud. These cumulonimbus clouds form a vortex under the influence of the forces exerted by the Earth's rotation. When the wind speed exceeds 17 meters per second near the center of this vortex, it changes from a tropical cyclone to a typhoon.   Typhoons vary in name and time of occurrence by location Many people enjoy surfing and other marine sports not only in Japan but also overseas. When checking the local weather forecast, it is important to note that typhoons are called differently depending on the location. Tropical cyclones, which can be considered the source of typhoons, occur not only in the Northwest Pacific and South China Sea, but also in warm oceans around the world. After the occurrence of a typhoon, it is swept away by the wind to various places, and its name changes depending on where it goes. It's called a cyclone when it's in the eastern part of Africa near the Indian Ocean and the South Pacific, where Fiji and Tonga are popular travel destinations for marine sports enthusiasts. A hurricane is also called a hurricane if it is located in the Pacific Ocean in the northern hemisphere, east of 180°E across the eastern edge of Russia, or in the Atlantic Ocean between Europe and Africa and the Americas. If it is in the Pacific Ocean around East Asia, which is west of 180°E in the Northern Hemisphere, including Japan, it is called a typhoon (Typhoon). The timing of occurrence is also very different between typhoons and hurricanes and cyclones. Typhoons and hurricanes primarily occur between June and November, whereas cyclones occur between April and December. If you enjoy marine sports such as surfing, be aware of typhoons, cyclones and hurricanes, depending on where you are going and when.   Typhoon size When looking at typhoon information, you may hear expressions like "large typhoon" or "super large typhoon". These "large" and "very large" expressions are classifications that indicate the size of the typhoon. In addition, it can be used as an alternative to the traditional Japanese typhoon. or not. In the case of large typhoons, the wind speed of 15 m/s or more is defined as a radius of 500 km to less than 800 km. It's a great way to get to know your neighbors and friends. It is the size that can fully fit into the In addition, super-sized typhoons are defined as having a wind speed of 15 m/s or more and a wind range of 800 km or more. A radius of more than 800 km exceeds the size of the city of Tomakomai in Hokkaido in the east from Tokyo and Ube in Yamaguchi Prefecture in the west.   How many typhoons are coming to Japan? Every year, a large number of typhoons occur over the ocean to the south and west of Japan, with an average of 25 occurrences per year for the 30 years from 1981 to 2010. Of these, only 11 are approaching Japan, with five to six coming within 300 km of a meteorological station from Hokkaido to Kyushu, and seven to eight in the Amami region of Okinawa Prefecture.   Typhoon types Typhoons can be broadly divided into two types of typhoons, depending on the damage they cause. One of the two types is a "rain typhoon" and the other is a "wind typhoon". A rain typhoon is literally a typhoon that is strongly affected by rain, while a wind typhoon is a typhoon that is strongly affected by wind. In both cases, you need to be careful of heavy rains and storms, but it is the wind typhoons that have the greatest impact on the sea. In the ocean, waves are caused by the wind blowing on the seawater. The size of the waves changes daily depending on the strength of the wind and the time of day it blows. This is the reason why the waves are higher when the wind blowing into the sea due to the typhoon and when the typhoon occurs. Before heading out to sea, pay attention to the wind direction and time of day, such as high tide.  Beware of dangerous half-circles; Beware the dangerous half-circle Many of you have heard that areas to the right of the typhoon are more likely to be affected by the wind I think it's because of this. Even among sailors, the right side of a typhoon is known as the "danger half-circle" because it is dangerous to navigate. In the northern hemisphere, where Japan is located, typhoons generally move from west to east. At that time, a counterclockwise wind current was formed on the ground toward the center of the typhoon. Because the direction of the wind that blows in and moves the typhoon is the same as the direction of the wind that moves the typhoon, the synergistic effect makes the wind stronger. It is an ironclad rule to stay away from the sea when a typhoon is approaching, but be especially careful in the coastal areas to the right of the eye of the typhoon, where the waves tend to be high due to strong winds.

What is the difference between a tropical cyclone and a typhoon?

Weather

Often, the weather forecast says, "A typhoon has turned into a tropical depression. Do you know the difference between a typhoon and a tropical cyclone? Before explaining the difference between a "tropical depression" and a "typhoon", I would like to first explain how a "tropical depression" is generated. First of all, what is a "tropical depression" is a low pressure whose maximum wind speed is 17.2m/s or less over the tropics or subarctic zone. A low pressure is a phenomenon in which a lot of water vapor evaporated from the sea rises and the air swirls around. By the way, all the "depressions" mentioned in the news in Japan are "tropical depressions". The reason why tropical cyclones occur in high-temperature oceans such as the tropics is that they need a lot of water vapor to occur, so they must be in high-temperature oceans. This is why they are often found in tropical and sub-arctic regions where the ocean temperature is high. And typhoon No. 19, which recently ravaged Japan, developed rapidly in this place. The speed at which it developed was the fastest in the world, and the level of danger was so high that some experts in the U.S. said it was so powerful that it was the highest non-existent level 6 in the Kagodeli ranking of typhoon strength. What is the difference between a "temperate depression" and a "tropical depression"? "Temperate" and "tropical" depressions are the same depression, but they are completely different. A tropical cyclone is made up of only warm air, but a temperate cyclone is made up of both warm air and cold air, so the type of air that is made up is different. A "temperate depression" is composed of warm and cold air, which causes a front to develop, whereas a tropical depression does not. How do typhoons occur? Types rarely appear out of the blue as typhoons, but basically they occur as "tropical cyclones". A basic typhoon forms in the southern sky and moves toward the northern sky, so it is called a "typhoon" only when it gains strength and its maximum wind speed exceeds 17.2 m/s. When the force drops and the maximum wind speed becomes less than 17.2 m/s, it is called "tropical depression" again. Briefly, a summary of how typhoons can be made (1) A "tropical cyclone" is generated. (The maximum wind speed at this time is less than 17.2 m/s.) If the maximum wind speed exceeds 17.2 m/s, it becomes a "typhoon". (3) After becoming a typhoon, it returns to a tropical cyclone when its power drops and its maximum wind speed drops to less than 17.2 m/s. (iv) Natural annihilation..... Just like that, typhoons are created and disappear. Incidentally, typhoons are most likely to occur from summer to autumn. The reason for this is that seawater, which is the fuel for typhoons, tends to evaporate due to high seawater temperatures. Next, I would like to explain what the storm and strong wind areas are, which indicate the size of a typhoon. Basically, the size of the typhoon is estimated by the size of the strong wind area. A high wind area is a range of places where winds are blowing or are likely to blow above 15 m/s. In weather forecasts, it is often represented by yellow or other colors. And the extent of the area where stronger winds are likely to blow is called the storm area. By even stronger winds here, I mean winds of 25 m/s or more. In weather forecasting, it is often represented by a red circle.   Where does the "tropical depression" that will come to be called a "typhoon" occur? In fact, no matter where it occurs in the sky, it is not called a "typhoon" if it comes over Japan. To be called a "typhoon," a "tropical depression" in the western North Atlantic Ocean (South China Sea, Philippine Sea, Sea of Japan, etc.) must have a maximum wind speed of 17.2 m/s or higher. If it occurs in the northern and southern Indian Ocean or the southern Pacific Ocean, and the central pressure is 17.2 m/s or more, it is called a cyclone; if it occurs in the northern and southern Atlantic Ocean or the northeastern and north-central Pacific Ocean, and the maximum wind speed is greater than 32.7 m/s, it is called a hurricane. Surprisingly, there is a difference in the direction of the swirl depending on where the tropical depression has developed. The northern hemisphere is counterclockwise and the southern hemisphere is clockwise. When the maximum wind speed is 32.7 m/s or higher, it is called a "strong typhoon"; when the maximum wind speed is 43.7 m/s to 54.0 m/s, it is called a "very strong typhoon"; and when the maximum wind speed is 54.0 m/s or higher, it is called a "fierce typhoon". Recap At the end of the day, the difference between a typhoon and a tropical cyclone is the difference in the size of the maximum wind speed. (Maximum wind speed of 17.2 m/s or more is a typhoon) In other words, there is no difference between a typhoon and a tropical cyclone except for the size of the maximum wind speed.
