Abstract:
The main characteristics of the general atmospheric circulation are as follows. Double polar vortex centers existed in the Northern Hemisphere. The circulation in Eurasian middlehigh latitudes showed a threewave pattern. The strength of Western Pacific subtropical high was a little weaker than normal years, and the intensity of south branch through was almost equal to normal. The monthly mean temperature was 7.0℃, 2.9℃ higher than normal, breaking the record since 1961. The monthly mean precipitation amount was 29.4 mm, which is almost equal to normal. One nationwide medium cold air process occurred in central and eastern China, and one strong cold air process in northern China in this month. Five obvious rainfall processes occurred in southern China, and three dust weather events happened in northern China. Strong winds and hails hit some areas of Jiangxi, Hubei, Hunan, and Guangxi.
