Abstract:The main characteristics of the general atmospheric circulation in August 2022 are as follows. There were two polar vortex centers in the Northern Hemisphere and they were stronger than normal. The circulation at middle-high latitudes of the Eurasia showed a latitudinal type, and the ridge to the north of Caspian Sea was unusually strong. The western Pacific subtropical high was stronger than that of the climatological normal, and its location was more westerly compared to that in normal years. The monthly mean temperature across China was 22.4℃, higher than normal (21.1℃) by 1.3℃, and the monthly mean precipitation was 82.4 mm, 23.1% lower than normal (107.1 mm). During this month, the high temperature days in China were abnormally more as the result of the persistent influence of the regional high temperature events. The meteorological drought condition in the Yangtze River Basin and other places continued to develop. Five tropical cyclones were active over the South China Sea and the western North Pacific, among which Typhoon Mulan (No.2207) and Typhoon Ma-on (No.2209) made landfall in China, but generally the number of landfall typhoon was less than usual. Convection events occurred frequently and there were eight torrential rain processes in this month, causing localized serious damages.
