Abstract:The following are the main characteristics of the general circulation of atmosphere in January 2014. There are two polar vortex centers in the Northern Hemisphere located more southward than normal years. The circulation presents latitudinal patterns in middle high latitudes. The south branch trough is averagely located near 70°E, being more westward than normal years. Besides, the subtropical high is a little weaker than normal years. The monthly mean precipitation is 6.2 mm, 53.0% less than the normal (13.2 mm). The monthly mean temperature is -3.4℃, 1.6℃ higher than the normal (-5.0℃). There is one cold air process nationwide and four rainfall processes in the month. Lack of rainfall has caused meteorological drought in the northern winter wheat region. Meanwhile, large scale fog and haze weather appear in the central and the east of China. Moreover, cryogenic snow weather hit the south of China.
