Abstract:
The main characteristics of the general circulation in August 2014 are listed as follows: There are two polar vortex centers in the Northern Hemisphere. In the middle high latitudes, the circulation presents a four wave pattern. The subtropical high lies southwards and is stronger than its climatological mean. Meanwhile, monthly mean precipitation amount is 104.4 mm, which is 0.9% less than its climatological mean (105.3 mm). Monthly mean temperature over China is 20.6℃, which is a little lower than its climatological mean (20.8℃). There are 8 severe rainfall events with extreme daily precipitation records observed at some stations in China. No typhoon forms over the northwestern Pacific Ocean and the South China Sea in August, which happens firstly since 1949. The only active typhoon is No.1314 Genevieve, which comes from the eastern Pacific. Some low temperature and sunlight lack events happen in the middle and lower reaches of Yangtze River region.
