National Climate Center: At present, the high-temperature heat wave event in China is the strongest in 6 1 year. What are the characteristics of this process?

Since June this year 13, the comprehensive intensity of regional high temperature events has reached 196 1, which is the strongest since the complete meteorological observation record. This time, the high temperature is 196 1 year, which has the longest duration and the largest coverage above 40℃. At present, the high temperature heat wave event in China is the strongest in 6 1 year. What are the characteristics of this process?

This process has the characteristics of long duration, wide range, great intensity and strong extremes.

Long duration: According to the statistics of the National Climate Center, this high temperature event has lasted for 64 days, exceeding the 62 days in 20 13, and the longest duration since 196 1.

Wide range: According to the statistics of the Central Meteorological Observatory, since June 13, the coverage area of high temperature above 35 degrees has reached 53 10000 square kilometers, affecting the population1/0000. There are 16 provinces, autonomous regions and municipalities with extreme high temperature above 40 degrees in the central and eastern regions, with an area of10.5 million square kilometers, affecting 340 million people. Coverage above 40 degrees is the largest in history. Strong and extreme heat wave weather process: for the central and eastern regions of China, the extreme high temperature above 44 degrees is relatively rare in the observation history, but in this wave of heat wave weather in 2022, the high temperature of 44 degrees is common, and extreme high temperatures above 44 degrees have appeared in Hebei, Hubei and Chongqing. The daily maximum temperature of 262 national meteorological stations in Hebei, Shaanxi, Sichuan, Hubei, Jiangsu, Zhejiang, Fujian, Guangdong, Qinghai and other places is equal to or exceeds the historical extreme value, exceeding 20 13 (187) and 20 17 (133). Therefore, the Central Meteorological Observatory issued the first national high-temperature red warning since the establishment of the early warning mechanism. There is no doubt that we are experiencing unprecedented extreme high temperature weather. Summary: High temperature is a disastrous weather, which easily makes people tired, irritable and irritable. The high temperature period is the frequent period of cerebrovascular diseases, heart diseases and respiratory diseases, and the mortality rate increases accordingly, especially for the elderly. For rural areas, continuous high temperature weather will also lead to high temperature and heat damage in agricultural production. As a result, the grain is not full, the grain weight decreases, and the agricultural output will be greatly affected.
