A coupled general circulation model in a zonal belt is used to simulate the variation of circulationfeatures in the process of uplift of the Qinghai-Xizang Plateau.The results reveal that the heatingrates of the Plateau increase with the rising of the Plateau topography,and the latent heating compo-nent in the heating field tends to be the most important heating factor.The uplift of the Plateau en-hances the upward motion,intensifies the pressure systems in the high and low level atmosphere,re-inforces Southeast Asia monsoon strength,increases precipitation and severely decreases the surfacetemperature over the Qinghai-Xizang Plateau.However.the basic structures of the general circulation do not vary much due to the uplift of theQinghai-Xizang Plateau.and it is the land-sea distribution that is the decisive factor to form the pre-sent circulation pattern and monsoon.Therefore,to simulate the paleoclimate during the geologicalperiod people should consider more factors,especially the land-sea distribution.
