The hot weather has been going on for many days, when will the hot process basically end?

The China Meteorological Observatory predicts that this round of hot weather will last until the end of the month, and firmly believes that until the end of the month, the hot weather will gradually lessen, and it is not as hot as it is now. In fact, around the beginning of September every year, the heat gradually disappears and the cool autumn begins. Therefore, friends only need to persevere for more than ten days now, until the ambient temperature decreases, and naturally it is not so hot.

In hot weather, we must pay more attention, after all, since the beginning of summer, there have been cases of heat stroke in several regions, and there are even 13 heat stroke patients in the hospital outpatient clinic in one day. I heard that some people get heat stroke on the way home from work on foot, and some people get heat stroke when they go out for a walk, which is enough to show that the hot weather is still very damaging to the body. Therefore, during this time, everyone must take measures to prevent heat stroke from high temperatures, and when carrying out outdoor sports, try to avoid the highest temperature period, such as between 10 am and 4 pm, when the natural light during this time period is relatively strong.

In view of this kind of hot weather, it is very necessary to prevent heatstroke. Especially for outdoor workers, it is necessary to prepare the corresponding heatstroke prevention medicine in advance. In addition, employers should also try to avoid allowing workers to work directly in high temperatures.

You can choose to avoid the hot period, and the best choice is to work in the evening or early morning. If you walk around under the scorching sun or do physical work for a long time, you will also get heat stroke in mild cases, and in severe cases, you will get heat stroke, which is extremely harmful to your health. If you have to go out at this time, you must do a good job of sun protection and isolation measures, such as wearing a sun umbrella, wearing a sun hat or wearing sunscreen, etc., which can effectively alleviate the damage of ultraviolet light.

In addition, it is necessary to drink more water, eat foods high in nutrients frequently, maintain adequate sleep, and improve the body's immunity.

Maybe after this dog day, the heat will gradually disappear, and this year's weather is very extreme, so we should pay attention to preventing heat stroke when we work outdoors or go out.

It's going to be over soon, and it's now relatively close to autumn, and the temperature should drop so that it's not too hot.

According to the monitoring of the National Climate Center, in the past few days, China has suffered from continuous high temperature weather, and the current high temperature event has lasted for more than 30 days, affecting more than 900 million people. In June this year, the global average temperature was about above average, the highest since 1979.

The 2020 high temperatures ended on September 2.

Chongqing Meteorological Bureau released this autumn's climate trends**. In the autumn of 2020 (September to November), the temperature in Chongqing was higher than normal and last year, and the precipitation was higher than normal. Starting from September 2, all parts of Chongqing will enter the autumn rain period in western China one after another, which is earlier and stronger than usual, and the intensity of the start time is late compared with last year. In early autumn and September, there is no obvious low temperature period in most areas of the city.

According to the traditional Chinese lunar calendar, after the beginning of autumn, there will be 24 "autumn tigers"; It is only after the summer heat (August 23) that the temperature can slowly drop. After the beginning of September, there is generally no more hot weather above 35 degrees. In other words, it will take another month or so for the hot weather to end.

High temperature and heat waves make the human body unable to adapt to the environment and exceed the tolerance limit of the human body, which leads to the occurrence or aggravation of diseases and even death, and the same is true for animals; At the same time, high temperature and heat waves can also affect the growth and development of plants, reducing crop yields.

The process of high temperature and heat wave will also exacerbate the occurrence and development of drought. In addition, water consumption and electricity consumption have risen sharply, which has a great impact on people's lives and production. In addition, high temperature heat waves often make people irritable, and even delirious, which is easy to cause public disorder, accidents, poisoning, fire and other incidents, which are the indirect effects of high temperature heat waves.

Generally speaking, after the heat is over, the temperature will slowly drop, and after the white dew (September 8), the temperature difference between day and night will increase, and it is difficult to have a high temperature weather. Therefore you have to endure for twenty days.

As soon as September arrived, the autumn breeze was cool. So it ended quickly.

The highest temperature of the day generally occurs around 2 p.m., because the maximum daily temperature of the air near the surface occurs 1 to 2 hours after the maximum solar altitude angle under clear clouds, light winds, and no temperature advection, and 12 noon is the time when the solar altitude angle is at its maximum. So the highest temperature of the day usually occurs around 2 p.m.

When the sunlight hits the ground, it heats the ground, and the heat absorbed by the ground is released to dry the air, so after the ground is heated, it will take a while to make the temperature rise. After noon, the heat emitted by the ground is still less than the heat supplied by the sun until the afternoon.

At two or three o'clock, the ground temperature can rise to the highest, and the temperature is the highest.

The high-temperature pre-lead meter will end around mid-August.

According to historical data, the summer heat lasts for at least 40 days, which is what we often call dog days. On dog days, the average temperature is above 35. If you don't stay in an air-conditioned room, you will feel like your whole person is melting.

Generally speaking, summer is the hottest time, after which people feel much more comfortable. The hot weather starts in mid-July and ends in mid-August, but the exact number of days may vary from year to year depending on the weather phenomenon.

Because the hot weather conditions are different in each region. Like the beginning of June this year, it was hot in the north and rainy in the south. After entering July, it is the opposite, with rainy weather in the north and hot weather in the south.

What you need to know about dealing with hot weather

1. Pay attention to ventilation in the house, only when the air is circulated, can you breathe fresh oxygen, and the spirit will be good. Because when blowing the air conditioner at home, in order to ensure a better effect, the doors and windows will be closed tightly, if there is no ventilation system, the whole person will be drowsy, and it is not good for the body for a long time.

2. After strenuous exercise outdoors, do not blow directly on the air conditioner, because the dilated pores will close quickly after encountering cold air, and the sweat in the body cannot be discharged, and there will be many potential dangers to the body if left in the body.

3. We must ensure adequate sleep, in hot weather, the heart is excited, if the sleep is insufficient, the body will not be able to bear. And remember to drink plenty of water.

The coldest and hottest time of the day.

The highest temperature of the day usually occurs at 2 p.m. (2 p.m.), when the atmospheric radiation is at its strongest. At 12 noon, solar radiation is at its strongest, and at 1 p.m. at 13 o'clock, it is the time when ground radiation is at its strongest. (And the coldest time of the day is around sunrise.) ）

12 noon is the time of the day when the sun is at its highest (and the solar radiation is the strongest), and it is also the time when the ground receives the most solar heat. But the temperature reaches its highest of the day at 2 p.m. (2 p.m.).

At 2 p.m. (2 p.m.), the temperature reaches its highest value of the day.

12 o'clock in the afternoon, indeed.

The highest version of the sun (the strongest solar radiation) is also the time when the ground receives the most solar heat, but at this time, the ground gets more solar energy than the ground loses more heat, and the ground temperature rises further, and at about 13 o'clock, the solar heat obtained by the ground is equal to the heat lost by the ground, and the ground temperature reaches the highest value, and the ground then transmits this heat to the atmosphere for about 1 hour, so at 2 p.m. (that is, at 14 o'clock), the temperature reaches the highest value of the day. (Hope adoption).

If it's a sunny day.

In winter, it's around 2 o'clock.

In the summer, it's around 3 o'clock.

The beginning of autumn on August 7 this year, it is estimated that it will be very hot after the beginning of autumn, and it will be really cool until August 18.
