High temperature weather in various places

"Occupy" hot search

High temperature incidents have continued for more than 30 days

It affects the population of more than 900 million people

There are also cases of medical treatment or even death due to heat irritation

Why is it so hot?

Since June 13, my country has emerged for the first regional high -temperature weather process this year. It has a wide range, long duration, strong extremes, and great impact. As of July 12, the high -temperature incident has lasted 30 days, covering a land area of ​​50.21 million square kilometers, which has a population of more than 900 million people.

The highest temperature of 71 national meteorological stations in the country broke through the historical pole, of which Hebei Lingshou (44.2 ° C), Tancheng (44.1 ° C), Zhengding (44.0 ° C) and Yunnan Yanjin (44.0 ° C) daily reached 44 ° C 44 ° C above.

Since entering the 21st century, the typical years of continuous high temperature events in my country are 2003, 2013, 2017, etc. Generally speaking, this year's high temperature incident starts earlier than the above three years, and the number of duration and historical extreme stations is not as good as these 3 years. Although the scope and the highest temperature in the single station are not as good as 2017, it has exceeded 2003 in 2003, but it has exceeded 2003 in 2003, but it has exceeded 2003 in 2003, but it has exceeded 2003. And 2013.

Meteorological experts pointed out that the continuous La Nina incident has provided an important climate background condition for the development of high temperature in the south since June. Especially in July, the development of heating and high pressure bands in the middle latitude was strengthened, leading to large -scale high temperature weather.

According to statistics, in the summer of most La Nina incidents, the Western Pacific subtropical high -pressure (referred to as auxiliary high) was easy to north. Since late June, the deputy high north, especially the typhoon "Siaba" in early July, the deputy high enhanced the west extension, Iran's high pressure east, and combined with the high pressure of the mid -latitude continent. High -pressure bands, which causes large -scale high -temperature weather. In addition, the water vapor carried by the auxiliary high causes a greater humidity in the central and eastern regions, making the body feel higher.

There are many people diagnosed in many places, and there are already death cases

On July 10, the Huaxi Hospital of Sichuan University had been treated with three thermal radiation patients. One of them was aggressive due to the illness and multiple organ failure. But eventually died unfortunately.

In the past week, Zhejiang has continued to have high temperatures. As of 12:00 on July 12, 51 high -temperature red warnings have been released to refresh historical records. According to statistics, Lishui Middle Hospital has been diagnosed with 3 patients with fever in the past week. One of the 70 -year -old women did not pay attention to the prevention of heat at home. , Still rescue.

According to Henan TV, in June this year, a man in Zhengzhou suddenly coma because of heat stroke. When the ICU ward was taken to the hospital for rescue, the doctor monitored the core temperature of his body had reached 42.3 degrees. All the organs in the body were like "cooking" in the water. For thermal radiation, that is, severe heat stroke.

Hyattic = heat stroke? not that simple!

Understanding in popularity is that thermal radiation disease is the most dangerous and serious heat stroke.

Some people may think: Isn't heat stroke very common? Don't take it lightly! Severing stroke can be divided into three categories: threatened heat stroke, light heat stroke, and heavy heat stroke.

Thermal radiation is the most serious type of heat stroke. The core temperature of the patient's body rises rapidly, and the central nervous system abnormalities and multi -organ system damage will occur. If you can't get timely and effective treatment, the mortality rate is extremely high!

High temperature, high humidity climate and high -intensity physical activity are the most important risk factor leading to thermal radiation disease.

How long does it take to get hot?

According to the forecast of the Central Meteorological Observatory, in the next 12 days (July 15th to July 26th, 2022), there are high temperature weather in the south of China and South China in my country. From 15th to 16th, there were high temperature and rainy weather in the Sichuan Basin, Guanzhong, Jianghan, Jianghuai, Jiangnan, Jiangnan, South China, etc., and the highest temperature was generally 35 to 38 ° C and local 39 ° C. From 17th to 20th, the rainfall process will occur in the Sichuan Basin, Jianghan, Jianghuai, Jianghuai, Western Jiangnan and northern parts of the northwestern part of South China. High -temperature weather can be relieved. Southeast Jiangnan and eastern South China will continue to be high -temperature hot weather. After the 21st, the high temperature in the south will develop again, and the scope will expand. The maximum temperature in Fujian, Jiangxi, and southern Zhejiang can reach 39 to 41 ° C.

The National Climate Center predicts that in the next 15 to 30 days (July 27 to August 11, 2022), the temperature in most areas in my country is higher than the same period of the same year. , Southern Shandong, most of Henan, Hubei, northern Hunan, Chongqing, eastern Sichuan, northern Guizhou, Tibet, south of Shaanxi, northern Xinjiang and other places are 1 to 2 ° C. There are many high temperature days in the above -mentioned parts, and there may be a longer -temperature weather process with a longer duration (July 28th to August 2nd, North China, Central China, Central Central China, East of Southwest China, Tibet, and Northern Xinjiang; August 5th to On the 7th, North China, Central East China, Central China Central China, and Northeast China; August 9th to 11th, most of North China and East China), high -temperature heat waves need to prevent the adverse effects of high temperature heat waves on people's production and life and power supply.

Doctor reminds: It is most important to deal with heat stroke, timely processing

Doctors remind: We must improve the vigilance of threatened heat stroke symptoms, and timely identify and avoid aggravation and progress of the condition.Secondly, pay attention to the relatively weak special groups such as the elderly and children. It may be strict in summer, and even because they are afraid of a cold, they are unwilling to blow air conditioning, which leads to heat stroke. The symptoms of such people are "hidden" and it is not easy to detect.For thermal radiation, the focus is on prevention!

Preventing the occurrence of labor -type thermal radiation diseases should pay attention to protecting when outdoor activities. It is best to have a process of gradually adapting to avoid directly from cool areas (such as air -conditioned rooms) to high temperature outdoor areas.At the same time, pay attention to replenishing water and salt, or sports drinks containing electrolytes.

In response to the prevention of class typical thermal radiation diseases, it is necessary to control the environmental temperature, increase or decrease clothes in a timely manner, and drink plenty of water; be careful not to put children alone in a small space such as cars.
