Abstract:The main characteristics of the general atmospheric circulation in August 2024 are as follows. There were two polar vortex centers in the Northern Hemisphere and they were stronger than normal. The circulation at middle-high latitude of the Eurasia showed a two-trough and two-ridge pattern. The location of the western Pacific subtropical high was more westward and northward compared to that in normal years. In August, the monthly average precipitation in China was 96.5 mm, 9.9% lower than normal (107.1 mm), and the monthly average temperature was 22.6℃, higher than normal (21.1℃) by 1.5℃. During this month, the high temperature days were more than normal for the same period of the year. The continuous high temperature weather in southern China was highly extreme, and meteorological drought developed along the middle and upper reaches of the Yangtze River. Five torrential rain processes occurred in China, and rainstorm events appeared frequently in northern China, with high overlap of rainstorm-hit areas and strong disaster causing ability. There were six tropical cyclones active over the Northwest Pacific in August, and no tropical cyclones formed or passed through the South China Sea or landed in China. Severe convection events occurred frequently and dispersedly, causing localized serious damages.
