What happened to the weather this year? Is it hot?

? On July 28th, the Central Meteorological Observatory raised the high temperature warning from blue to yellow. China's high temperature warning is from low to high, and * * * is divided into three levels: blue, yellow and orange. The level is yellow, which means that the highest temperature in most areas of two or more provinces (autonomous regions and municipalities) has reached 37℃ and above in the past 48 hours, and it is expected that the high temperature of 37℃ and above will continue to appear in these areas in the next 48 hours.

According to the forecast of the Central Meteorological Observatory, on the 28th, during the daytime, most of Beijing, western Tianjin, central and western Hebei, most of Shanxi, eastern Shaanxi and most of Guanzhong, western Ningxia, central and western Henan, northern Shandong, western Hubei, northeastern Sichuan Basin, most of Chongqing, eastern Guizhou, most of Hunan, western Jiangxi and southwestern Zhejiang have high temperature above 35℃, and the local maximum temperature can reach 37℃-38℃. There will be high temperature of 35℃-37℃ in the central and western Inner Mongolia, central and western Gansu, Turpan basin in Xinjiang and southern Xinjiang basin, and the highest temperature in some areas can reach above 40℃. On the 27th, the highest temperature in parts of Inner Mongolia and Gansu exceeded 40℃, setting a new high temperature record this year. The picture below shows the national high temperature map.

Reason:

1. Why is it so hot all over the country?

Meteorologists explained that the main reason for the high temperature this year is that the two forces of high-altitude subtropical high and continental warm high converge to form a strong warm high, which controls the northern part of China; In addition, there is no cold air activity and updraft on the ground floor, so it can't rain and the humidity is very high, so it presents sultry weather.

2.？ Why does North China last "sauna days"

Zhao, an expert from the Central Meteorological Observatory, said that this kind of weather in Beijing, Tianjin and other places is a typical hot and humid weather, commonly known as "sauna days". Zhao said that the formation of sauna days is closely related to the monsoon climate in China. In summer, China is dominated by humid ocean monsoon, and the air is relatively humid. Therefore, the high temperature weather formed by radiation heating to a certain extent is mostly manifested as "sauna days", especially in the eastern part of northwest China, North China Plain and its south. Usually, in this case, the cold air force is weak as a whole, and the hot weather usually lasts for several days or even ten days, and in extreme cases it may reach dozens of days.

Method:

So how did you spend this summer? This has become a concern for everyone.

No.65438 +0 diet summer vacation

The weather is very hot, and a lot of water is lost from the body in the form of sweat. At this time, it is necessary to supplement a lot of water to ensure the normal metabolism of the human body. Boiled water in summer is the best way to replenish water. Don't use a lot of ice water and drinks because you are greedy for cold. A small amount of carbonated drinks will cool down and relieve summer heat, but a large amount of carbon dioxide will enter the human body, which will inhibit beneficial bacteria, destroy the digestive system, and cause bloating and gastrointestinal dysfunction.

In addition, mung beans, bitter gourd, cucumber, watermelon and duck meat are all essential products for heatstroke prevention, especially mung beans, which have the functions of clearing away heat and quenching thirst, clearing away heat and detoxifying, and are the best prescription for summer heat.

No.2 warm water shower

People are used to washing with cold water after exercise to reduce body heat. Actually, this method is unscientific. Not only can it not keep cool, but it may also cause symptoms such as colds. Taking a hot bath or warm bath after sweating can play a more important role in cooling down and relieving summer heat. The body temperature is 30~40℃, and it can be washed with water close to the body temperature, which can maintain the normal circulation of blood, open capillaries and carry out normal metabolism.

No.3 Chu xing sun protection

When you go out, you must take good sun protection measures, rub a proper amount of sun protection products on your body, or carry umbrellas such as sun umbrellas, which will help to block out strong light and avoid sunburn. Moreover, it is best to wear cotton or gauze light clothing, which absorbs sweat and breathes air, which helps the body to dissipate heat. Take heatstroke prevention drugs with you, such as Huoxiang Zhengqi and Ren Dan, in case of emergency. Travel time is best to avoid periods of strong sunshine and pay attention to proper lunch break.
