Abstract:
The main characteristics of the general atmospheric cirulation in November 2015 are listed as follows: There is one polar vortex centre in the Northern Hemisphere. In the midhigh latitudes, the circulation presents a threewave pattern. The average south branch trough is located around 90°E. The northwestern Pacific subtropical high is stronger than normal, located more westward. Meanwhile, monthly mean precipitation amount is 39.4 mm, which is 1.1 times more than its climatological mean. Monthly mean temperature is 4.1℃, being 1.2℃ higher than normal except the North and Northeast China. Two cold air processes and 4 severe rainfall events take place with extreme precipitation records observed at some stations in China. Moreover, the precipitation amount of Jiangnan, South China and other parts is 2-3 times more than normal. In addition, three heavy pollution weather processes are experienced during this month.
