Abstract:The main characteristics of the general atmospheric circulation in March 2022 are as follows. There were two polar vortex centers in the Northern Hemisphere. The 500 hPa geopotential height presented the distribution of an anomalous four-wave pattern in the mid-high latitude of Northern Hemisphere and the air flow was straight in Asia. The strength of Western Pacific subtropical high was a little higher than that in normal years, and the south branch trough was a little weaker. There was only one strong cold front process in March. The national average temperature in March was 7.2℃, 2.4℃ higher than the normal and recorded the first in the same period since 1961. The monthly mean precipitation amount was 36.7 mm, 25% more than in normal period (29.4 mm). Three rainfall processes occurred in this month, causing severe weather such as heavy rain and thunderstorm. In addition, there were two large-scale sand-dust weather processes in northern China. Droughts appeared and developed in Huanghuai Region and Jianghuai Region.
