Abstract:
The main characteristics of the general atmospheric circulation in November 2022 are as follows. There were two polar vortex centers in the Northern Hemisphere. The East Asian trough and the southern branch trough were weaker than in the same period of normal years. The western Pacific subtropical high was stronger during this month. The monthly mean precipitation across China was 26.9 mm, which is 33.2% more than normal (20.2 mm). The monthly average temperature was 4.8℃, 1.5℃ higher than the temperature (3.3℃) in the same periods of normal years. The cold and warm temperatures fluctuated greatly during the month. The cold air was not so active in the early and mid dekads. Accordingly, the temperature was higher and the precipitation was less in most of China. However, in the later period, affected by the strong cold air and the active southern branch trough, the temperature dropped sharply and precipitation increased significantly. In addition, there were one nationwide cold wave process and two widespread persistent fog-haze weather processes.
