摘要
Abstract
The main characteristics of the general atmospheric cirulation in November 2015 are listed as fol-lows:There is one polar vortex centre in the Northern Hemisphere.In the mid-high latitudes,the circula-tion presents a three-wave pattern.The average south branch trough is located around 90°E.The north-western 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.关键词
