The high temperature in the south is endless. On the 21 ST, the high temperature resumed and it was hot until the end of July.

since July, with the western Pacific subtropical high continuously extending westward and strengthening, under the influence of clear-sky radiation, sinking and warming, there has been a large-scale continuous high-temperature weather in southern China, and the highest temperatures in many places have reached or exceeded historical extremes.

1. The high temperature lasts for a long time and is extremely significant.

from July 5 to 17, 222, the highest temperatures in eastern Sichuan, southwestern and northern Chongqing, northeastern Yunnan, southwestern Shaanxi, northwestern Hubei, southern Jiangsu, Shanghai and Zhejiang exceeded 4℃, and the local temperature in Yanjin, Yunnan reached 44℃. 154 national meteorological stations in Yunnan, Guizhou, Sichuan, Chongqing, Qinghai, Gansu, Ningxia, Shaanxi, Zhejiang, Anhui, Jiangsu, Shanghai and Tibet * * * reached or exceeded the July extreme value, and 61 national stations reached or exceeded the historical extreme value. On July 13th, the highest temperature (4.9℃) in Xujiahui, Shanghai tied the highest record since meteorological records (since 1873).

The number of high temperature days in central and southern Shaanxi, Sichuan Basin, Jianghuai, Jianghan and Jiangnan is 5-9 days, and more than 1 days in southern Shaanxi, Sichuan Basin, western Hubei, southern Jiangsu and Anhui, Shanghai, Zhejiang, central and northern Jiangxi and northern Fujian.

2. how will the hot weather develop in the future?

from July 18 to 2, 222, the overall intensity of high temperature in southern China weakened and its scope narrowed.

however, as the subtropical high extends westward, the high temperature weather in the south will develop again on 21st, and then the subtropical high will be connected with the Iranian high pressure, which means that the subtropical high is very strong, and this high temperature weather process cannot be underestimated!

It is predicted that from July 21st to the end of July, 222, there will be a large range of continuous high temperature weather above 35℃ in Sichuan Basin, Jianghan, Jianghuai, Jiangnan, South China, Southern Xinjiang Basin and Western Inner Mongolia, with the highest temperature in Zhejiang, Fujian, Southern Xinjiang Basin and Western Inner Mongolia exceeding 4℃. There will also be intermittent high temperature weather in central and southern North China, Huanghuai and Shaanxi.
