Why was it so hot?

Dangerous heat in Tokyo

According to the Japan Meteorological Agency, the sunny and strong sunlight shined mainly on the Pacific side from Tohoku to Kyushu, and warm air also flowed in from the southwest side, causing the temperature to rise.

The highest temperature during the day was


just 39 degrees in Hachioji, Tokyo, which was dangerous.


37.9 degrees in Nerima, Tokyo


37.8 degrees in Hatoyama, Saitama and Tsuchiura, Ibaraki


▽ 37.4 degrees in Sano, Tochigi.


▽ In Onahama, Iwaki City, Fukushima Prefecture,


it became extremely hot

at 37.3 degrees Celsius

.



It was the first hot day in Tokyo at 36.8 degrees Celsius.

40 degree forecast In Saitama Kumagaya ...

In Kumagaya City, Saitama Prefecture, where the maximum temperature was expected to be 40 degrees Celsius, strong sunlight shined from the morning, and many people were seen holding parasols and walking with small fans around JR Kumagaya Station.

The mist shower that the city installed in front of the station as a measure against the heat was also in operation, and parents and children reached out to the shower to keep out the heat.

The maximum temperature was 37.2 degrees Celsius, which was the hottest year.



A woman in her twenties said, "The sun hurts. It's hot outside and I'm walking looking for shade. I'm wearing a cooling mask, but it's so hot that I can't feel it."

Why did it get so hot?

The maximum temperature on the 10th was 5 to 7 degrees higher than normal in Tokyo, and it was the hottest in various parts of the Kanto region.

Why did it get so hot in Kanto?

Factors 1. Warm air in the south drawn by extratropical cyclones

According to the Japan Meteorological Agency, the first reason is "warm air in the sky."



On the 10th, 1500 meters above the Kanto area was filled with warm air of about 22 degrees, which is 2 to 3 degrees higher than normal.

If you add 15 degrees to the temperature in the sky, it will be about the temperature on the ground.

It was a heat wave of 22 + 15 = 35 degrees or more.

The background of the temperature above normal is the extratropical cyclone that changed from the typhoon near northern Japan.

As the low pressure system drew the southwesterly wind, warm air from the sea in the south flowed into Kanto and other areas.

Factor 2. Intense sunshine

Then, it was sunny mainly on the Pacific side from the southern part of Tohoku to Kyushu, and the strong sunlight shined and pushed up the temperature on the ground.

Factor 3. Dry foehn

Furthermore, in the Kanto region, the terrain and weather conditions overlapped, and the heat reached a dangerous area in Tokyo.



Due to extratropical cyclones, westward winds are blowing from eastern Japan to western Japan.

Especially in the Kanto region, dry air blows down over the western mountains, and a phenomenon called "dry foehn", in which the temperature rises in the foothills, overlaps, and it is thought that the temperature has risen even higher, especially inland.

The record of the highest temperature

Since the Japan Meteorological Agency began collecting statistics in the Meiji era, the record for the highest temperature in Japan was 40.8 degrees Celsius, which was observed in Yamagata City in July 1933, 88 years ago.

Recently, the record has been updated one after another.

The record for Yamagata City was updated at 40.9 degrees, which was observed in Tajimi City, Gifu Prefecture, in August 2007, 14 years ago.



Thereafter, the recording update after another of


▽ 2013 years (2013) in August just 41 degrees in Nishitosa Kochi Prefecture Shimanto


and


41.1 degrees in July of ▽ 3 years ago · 2018 in Kumagaya, Saitama Prefecture I observed it.



In 2018, it became a hot summer with 40 degrees Celsius, and 5 of the 11th place records have been observed.



And in August of last year, it also observed 41.1 degrees in Hamamatsu City, Shizuoka Prefecture, which was in line with the national record of Kumagaya City, Saitama Prefecture.

What are the key points for heat stroke countermeasures?

The intense heat is expected to continue on the 11th, and the maximum temperature during the day is


38 degrees in Kumagaya City, Saitama Prefecture


▽ 36 degrees in central Tokyo and Gifu City, Maebashi City, Kofu City


▽ Osaka City, Nagoya City, Tottori It is


expected to be

35 degrees in the city and Yokohama city

.



Heat stroke that requires continued vigilance.

The points of countermeasures are summarized.

Firmly hydrate!

First of all, it is important to rehydrate.



To avoid dehydration, try to drink water frequently even if you are not thirsty.

When you sweat a lot, it is important to remove salt in addition to water with a sports drink or oral rehydration solution.



Also, if you are outdoors, wear a parasol or hat to prevent direct sunlight.

It is also effective to wear airy clothes and loosen the collar.

Beware of "Tropical Nights"

In Kanto, the minimum temperature is expected to be a "tropical night" without falling below 25 degrees Celsius until the morning of the 11th, and there is a risk of heat stroke even at night.


Keep "normal temperature" water near your bed and drink it before going to bed, when you wake up, or when you wake up.

It is also important to keep the air conditioner on until morning and sleep soundly to recover your physical strength.



▽ Cool the room sufficiently before going to bed


▽ Keep the air conditioner on until morning


▽ Drink a glass of water before going to bed ▽

Put


"normal temperature" water on the bedside

and drink

when you wake up


▽ With an ice pillow etc. Cool the neck

Use "air conditioner"!

The most common place where heat stroke occurs is "house".

Every year, there are a lot of people who get heat stroke indoors.


Use air conditioning to keep the room cool so that the room temperature does not exceed 28 degrees Celsius.

Place a "thermometer" in the room to check the room temperature and humidity.

If you are an elderly person, set a standard for turning on the air conditioner, not "after it gets hot".



▽ Place a thermometer in the room and check "room temperature" and "humidity"


▽ Set the temperature according to "hot people"


▽ "room temperature 28 degrees" "humidity 70%" is a guideline for


turning on the air conditioner ▽ leave the air conditioner on Is a great deal!



● What if there is no air conditioner?


▽ Use blinds, blackout curtains, and "green curtains" made of plants to prevent direct sunlight


▽ Open windows to improve ventilation


Sprinkle water around the house


▽ Wrap ice or ice

pack with a

towel around the neck Cool the sides etc.

"Call out" to "elderly people"

Most of the people transported due to heat stroke are "elderly people aged 65 and over."

Older people are less likely to feel the heat and their basal metabolism is lower, which makes them colder than younger people.


If you rely on the experience, the countermeasures will be delayed if it is not hot yet.

Please set a standard and confirm the use of the air conditioner by having your family and people around you call directly to confirm the use of the air conditioner.

It is also important to rehydrate at a fixed time, not just at meal times.



▽ Family members and people around them should check the use of the air conditioner by "phone"


▽ The trick is to call again to check the situation after a few hours


▽ "Room temperature 28 degrees" and "humidity 70%" are guidelines for turning on the air conditioner


▽ Set a time and rehydrate

Children should be careful about their physical condition

Children have not yet developed a thermoregulatory function and are more likely to have a fever in their bodies.


In addition, it is short and easily affected by the reflection of the ground.

Adults need to be aware of changes in their physical condition and try to rehydrate because they cannot communicate their physical changes well.



▽ Observe carefully for changes in physical condition


▽ Call

out

frequently to check for changes in physical condition


▽ If you are sweating a lot or your face is red, rest in a cool environment


Put a

lot of ice Hold a water bottle


▽ Do not play outside for a long time

Measures against heat stroke and new coronavirus

It is summer to wear a mask as a countermeasure against the new coronavirus, but to prevent heat stroke, it is important to take a break and take off the mask when you can get a sufficient distance from people outdoors.



▽ Do not carry out heavy work


while wearing a

mask ▽ When giving

water as a first aid, provide newly purchased items without a mouth


▽ If there is a person who is ill in a hot place, suspect heat stroke To deal with
