For nearly a month, the high temperature has continued in many parts of the country, and now there are even death cases of heat stroke disease. It is reported that as of July 12, the high temperature event has lasted for 30 days, covering an area of 5.021 million square kilometers and affecting more than 900 million people. Everyone is very curious about why the high temperature last so long this year, and what is the reason for the high temperature? Let's take a look at it in detail.
According to CCTV News, the high temperature has lasted for a month since June 13, affecting more than 900 million people. In June, the southern part of North China, Huang Huai River and other places suffered from meteorological drought due to high temperature.
At present, 76 stations have broken the historical high temperature record, 20 of which exceed 42 ℃. From the perspective of spatial distribution that breaks the historical record, there are 23 stations in Hebei and 25 stations in Sichuan.
The main reason for the continuous high temperature weather in China is related to the high-pressure system. The recent high temperature is more unbearable, mainly because the air humidity in the south is relatively high, so the body feeling is more obvious.
With the further westward extension and northward uplift of the Western Pacific Subtropical High, which controls most areas in southern China, the high temperature weather in southern China may further develop.
Doctors remind that heat stroke is severe heatstroke, and the mortality rate is as high as 70% - 80%. Citizens should pay attention to avoiding outdoor activities during high temperature periods, and the key point is to avoid staying in a closed high temperature environment; Outdoor workers shall supplement water and electrolyte in time.
Don't just drink boiled water or mineral water. Drink light salt water or functional drinks to avoid electrolyte disorder; In case of dizziness, panic, excessive sweating and other symptoms, you should be alert to heatstroke. You must leave the high heat environment immediately. At the same time, you can drink ice water in small sips, 200-300ml of ice water in small sips, which will help reduce body temperature.
