Liu Yijun (Meteorological Observatory of Tibet Autonomous Region) Li Lin (Tibetan Plateau Institute of Atmospheric and Environmental Sciences,Lhasa)  
By using the routine surface data and 500hPa geopotential height of the northern hemisphere the climatological features of Tibetan monsoon is analysed. 1.In winter Tibet is influenced by western belt system from north to the plateau or south trough from south to the plateau and in summer it is influenced by the thermal low system in the Indian Peninsula and the Bengal Bay and the Plateau shear line. It is also affected by dilated high towards northwest from northwest pacific and dilated high towards east from Iran. 2.The spatial distribution of rainfall is different obviously and there exists two peak pattern in some regions.There is a tendency in the plateau of decrease in summer and increase in winter since 1980’s. 3.The mean temperature in summer and winter has increased since the middle of 1970′s.In some regions the increase extent is more than 2.0℃. 4.The biggest fluctuation of snowfall in winter in the plateau is located in the south border with high frequency of heavy snowstorm.The biggest fluctuation of rainfall is at the west part along the Yalung Zangbo Ribver,where flood or drought occurs alternatively in every summer.
