Abstract:
The main characteristics of the general atmospheric circulation in February 2013 are as follows: There were two polar vortex centers in the Northern Hemisphere with more stronger strength than normal years. Atmospheric circulation presented a three wave pattern in middle high latitudes. The south branch trough was to the west, which is not favorable for the transportation of water vapor. The West Pacific subtropica high was stronger than normal years. The monthly mean temperature was -1.2℃， higher than normal. The mean precipitation this month was 14.1 mm, 19.0% less than normal. Two cold air events affected China and fog and haze weather happened many times. Drought still lasted in the southwest of China, and severe snowstorms hit the south of Tibet.
