On August 5th, China issued 150 red high-temperature alerts. Sichuan had 75, Hubei had 39, Chongqing had 21, Henan had 14, and Shandong had 1. This news became a hot topic on August 6th.
According to China Weather Network, from 11:00 to 18:00 on August 5th, on the hourly ranking of China’s high temperatures, Sichuan and Chongqing occupied the top ten spots. In particular, Wuxi and Tongnan in Chongqing reached a high temperature of 42.3°C for several hours, topping the list.
As reported by the “Sichuan Daily,” from 14:00 to 19:00 on August 4th, Sichuan and Chongqing took the top ten spots on the national hourly high-temperature ranking. Wuxi, in particular, reached a temperature of 44.2°C on August 4th, breaking the local record for the highest temperature in history.
Xu Xiaofeng, President of the China Meteorological Service Association and former Deputy Director of the China Meteorological Administration, analyzed in an interview with Red Star News on August 5th that in recent years, there has been a clear upward trend in widespread high-temperature weather, indicating an accelerated pace of climate warming. The extensive high temperatures this year are mainly due to the prolonged control of the subtropical high-pressure system, which has affected Sichuan, Chongqing, and the Jianghuai region, leading to widespread high temperatures.
Xu Xiaofeng believes that this year, the subtropical high-pressure system reached northern China earlier, bringing prolonged sultry weather. He mentioned that after the beginning of autumn, it should gradually dissipate.
However, Xu Xiaofeng cautioned that with the decreasing range of the subtropical high-pressure system, there may be rainfall in the surrounding areas of the high-pressure system. For regions experiencing long-term high temperatures and drought, caution is needed regarding the rainfall brought by this intense convective weather system, as it may pose risks of geological disasters.
