摘　　要：利用１９８０～１９８２年的资料，揭示了夏季青藏高原上存在准１周、准半周和准１０ｄ的大气短周期振荡。Based on the data from 1980 to 1982,the short period atmospheric oscillations of quasi one week,quasi half week and quasi 10 days over the Qinghai Xizang plateau are shown to exist during summers.And there is a ahead of time correlation between those oscillations with vortex activities in some area of the east of the plateau and the precipitation in the lower reaches.
