Abstract:
The following are the main characteristics of the general circulation of atmosphere in July 2010.There is one polar vortex center in the Northern Hemisphere. The circulation presents a fivewave pattern in middlehigh latitudes. The intensity of five main deep troughs are stronger than or equivalent to that of trough in average conditions. The subtropical high shows an eastwest belt figure and it is stronger than the corresponding time of normal years. Mean precipitation in China is 121.2 mm in July 2010, and 5.3 mm higher than the averaged over many years. Meanwhile, the mean temperature in China is 22.8 ℃, and 1.4 ℃ higher than the averaged over many years (21.4 ℃). The main weather events in July were rainstorm and flooding occurring at the middle and lower reaches of the Changjiang River, Sichuan Basin, southeast of Northwest China, parts of HuangheHuaihe Plain and parts of Northeast China. Typhoons “Conson” and “Chanthu” made landfall in China. The hailstorm disasters happened in Jilin Province, Jiangxi Province, Inner Mongolia Autonomous Region and other parts of China, etc. Sustained high temperature weather occurred in South China, south of the lower reaches of the Changjiang River, ChangjiangHanjiang Plain, HuangheHuaihe Plain， North China, Northwest China and other parts of China, etc.
