Abstract:
The following are the main characteristics of the general circulation of atmosphere in March 2013. The polar vortex in the Northern Hemisphere lies further south than normal years. It has two centers, located over Europe and Northern Asia, respectively. There are four waves around the earth in middle high latitudes. The south branch trough is slightly weaker than the normal, and the Northwestern Pacific subtropical high is slightly stronger. The average precipitation around 〖JP2〗China is 26.1 mm, 11.5% less than the normal. The monthly mean temperature is 6.3℃, 2.2℃ higher than the normal, which is the 2nd highest value since 1961. There are 5 cold surge processes, during which the largest scale dust weather occurs from 8th to 11th March. Five major rainfall processes are seen in this month, and from 19th to 20th, Jiangnan and South China region experience the largest scale severe convective weather so far in this year.〖JP〗
