With GMS—5 water vapour images and meteorological data,water vapour transfer in upper troposphere over Qinghai-Xizang Plateau in June and July of 1995 is analysed. The results show that there are three types of circulation pattern for water vapour transfering toward Qinghai-Xizang Plateau in upper troposphere. They are west side ridge pattern,east side ridge pattern and out of phase pattern. The relationship between them and precipitation in the Qinghai-Xizang Plateau is also analysed.
