Abstract:
The main characteristics of the general atmospheric circulation in November 2020 are as follows. There were two polar vortex centers in the Northern Hemisphere. The circulation presented a threewave pattern in midhigh latitudes. The East Asian trough and the southern branch trough were weaker while the western Pacific subtropical high was stronger, located more westward. The monthly mean precipitation over China was 16.9 mm, which is 11 % less than normal (19.0 mm). One severe rain and snow process occurred from the 17 to 19 November, during which 〖JP2〗Enshi of Hubei Province and Dandong of Liao〖JP〗ning Province experienced severe rainstorm, and Mudanjiang, Jixi and Qitaihe of Heilongjiang Province and Tongliao and Chifeng of Inner Mongolia were hit by severe snowfall or extremely severe snowfall. The monthly mean temperature was 3.9 ℃, 1 ℃ higher than normal (2.9℃). During this month, there were four cold air processes, one of which was nationwide from the 18 to 22 November. Additionally, as the result of unfavorable diffusing condition of atmosphere, one foghaze event appeared in centralsouthern part of North China, west of Huanghuai Region, and Fenwei Plain during 10 to 17 November 2020.
