Abstract: National Satellite Meteorological Center has retrieved Atmospheric Motion Vectors from GMS-5 since 1997. This data provide quite detailed information on the wind field at the upper-level troposphere over east Asia, east Indian Ocean and west Pacific. Comprehesive analysis between the cloud motion vectors and observed precipitation data from 1998 to 2002 is made, which verifies that circulations in upper troposphere of summertime rainfall events in China can be concluded into three typical patterns:① The first pattern is often seen over the Changjiang river region and in the southeastern part of China from June to July whose rain belt is associated with an anticycloneridge at the upper troposphere, with precipitation cells in the diverging area between the subtropical westerly jet and the ridge or in the velocity diverging area of the tropical easterlies north of the ridge; ② The second pattern often occurrs in the southern part of China (Hainan, Guangdong and Guangxietc.) from July to September with the rainfall center locating on the right side of the upper deformation field and the west of the asymmetry anticyclone; ③ The third pattern happens frequently to the north of 30°N in China from July to August with the rainfall center lies in the southwesterly in front of the upper level westerly trough which occurrs primarily in north China. Evident indicates that, firstly air divergence at the upper troposphere is commonly seen in these three circulations; secondly, having a small wind component inwards, the area at the upper troposphere corresponding to the precipitation areas in the first and second patterns has anticyclone vorticity, while the precipitation areas in the third pattern are under the positive vorticity advection zone in front of upper westerly trough, which has a large component inwards. Besides, compared to the first one, happening around higher latitudes, with prominent jets and northerly component on the ridge, the second one occurs around lower latitudes, with indistinctive jets and southerlies on the ridge. The first circulation pattern has a close relationship with the location, movement and maintenance of the rainbelt in the flood season in China; the second one is related to the precipitation brought by the typhoon and the tropical weather system while the third one is a typical mid-latitude upper trough cold front precipitation. They are different in the persistence, influencing ranges and mechanism.
