Confirmed!The current high temperature incident reaches the strongest weather record in my country

According to the recent monitoring and evaluation of the National Climate Center, comprehensively considering the average intensity, scope and duration of the high -temperature heat wave incident, the comprehensive intensity of regional high -temperature events that has been from June 13 this year has reached the strongest meteorological observation record in 1961.

Chen Yan, chief and Zhengye Senior Tear of the National Climate Service Office, said that the process has the characteristics of long duration, wide range, strong intensity, and strong extremes. As of August 15, the high temperature incident has lasted for 64 days, the longest time since 1961 (more than 62 days in 2013); covering 1680 stations above 35 ° C and 1426 stations above 37 ° C, all of which are history. Two (second only to 2017, 1762 and 1443 stations), but the coverage of above 40 ° C is the largest in history; the number of high temperature and extreme stations is 262 stations, which have exceeded 2013 (187 stations) and 2017 (133 stops 133 (133 stations) To.

Since the summer (June 1st to August 15th), the average number of high temperatures in the country is 12.0 days, which is 5.1 days more than the same period of the year. It is the same period since the complete meteorological observation records in 1961. Southern North China, Most of East China, Central China, eastern South China, northeast of the southwest and most high temperature days in Xinjiang, western Inner Mongolia and other places are generally more than 20 days. Southern Jiangsu, Zhejiang, central and northern Fujian, most of Jiangxi, most Hunan, eastern Sichuan, Chongqing and other places for more than 30 days.

Since the summer, the high temperature daily days of Henan, Jiangsu, Zhejiang, Zhejiang, Hubei, Guizhou, Sichuan, Shaanxi, Shaanxi, Shaanxi, Shaanxi, and Shaanxi have been the largest in history since 1961. The 6 provinces (autonomous regions, municipalities) of Gan Ning and Shanghai, Hunan and Luna, Xianglun, are more than 2nd in history. Chongqing is more than 3rd.

A total of 914 national meteorological stations (37.7%of the number of nationwide total stations) in the country reached the highest temperature of extreme high temperature events. The temperature is flat or breaks through the historical pole, of which Zhushan (44.6 ° C) in Hubei, Chongqing Beiyi (44.5 ° C), Fengjie (44.4 ° C), Wuxi (44.0 ° C), Hebei Lingshou (44.2 ° C), Tancheng (44.1 ° C) , Zhengding (44.0 ° C), Yunnan Yanjin (44.0 ° C) has a maximum temperature of 44 ° C or above.

According to the forecast of the Central Meteorological Observatory, in the next 10 days (August 17-26), there will still be continuous high temperature weather in Sichuan Basin, Jianghan, Jianghuai, Jiangnan and other places. 35-38 ° C, the local area can exceed 40 ° C. After comprehensive research and judgment, the duration of the regional high -temperature heat wave event in my country will continue to be extended, and the comprehensive intensity will be further enhanced.

Yuan Jiashuang, deputy director of the National Climate Center, said in an interview with the media:

"With the intensification of future climate warming, the future extremely high temperature and strong water drop incident will show a variety of and reassess. At the same time, composite events in many areas, such as high temperature heat waves and drought composite events, extreme precipitation and sea level rising, storm waves The composite flooding incident caused by the factors will also increase the probability of occurring, and humans will face greater climate risk and influence. "

Chen Lijuan, chief forecaster of the National Climate Center, said in an interview with the media:

"From the perspective of climate state, it is normal to occur in high -temperature heat waves in summer, but this summer's high -temperature heat wave incident has continued to reach a very strong level, and there is a deep climatic scale behind it.

We have to face a reality: similar high temperature and heat will appear frequently in the future. The current global greenhouse gas has a very strong effect. In the context of global warming, the high -temperature heat wave incident will become a new normal.

Another feature brought by climate change has begun to appear: this year's high temperature appears earlier than the climate value, and the expected time is late than the climate value, that is, the features of high temperature starting early and long duration will be the characteristics of the high temperature. More and more prominent. "
