The circulation presents meridional patterns in middlehigh latitudes. The south branch trough behaves actively， and the mean position is located at 90°E nearby. The subtropical high is a little weaker than normal years, and the average south branch trough is also weaker than normal years. The monthly mean precipitation is 12.3 mm, and 29.4% less than normal （17.4 mm）. The monthly mean temperature is -1.6℃, and 0.1℃ higher than normal （-1.7℃）. There is one cold wave process nationwide.
