摘　　要：Using the mesoscale regional atmospheric model RAMS(The Regional Atmospheric Modeling System),the climatic effects of underlying surface vegetation changes of Tibetan Plateau were conducted the numerical simulation.The possible influence of vegetation variation on regional climate was studied.The results showed that the climatic effects of Tibetan Plateau were well represented in the upper troposphere(300 hPa).The heating effect and cooling effect caused by vegetation changes of Tibetan Plateau were inconsistent between land surface and upper air,and the cyclone(anticyclone) differences reflected in the flow field would enhance South Asia high in the higher troposphere(lower southwest vortex system),which might have an effect on the precipitation in Yangtze River basin.Using the mesoscale regional atmospheric model RAMS(The Regional Atmospheric Modeling System),the climatic effects of underlying surface vegetation changes of Tibetan Plateau were conducted the numerical simulation.The possible influence of vegetation variation on regional climate was studied.The results showed that the climatic effects of Tibetan Plateau were well represented in the upper troposphere(300 hPa).The heating effect and cooling effect caused by vegetation changes of Tibetan Plateau were inconsistent between land surface and upper air,and the cyclone(anticyclone) differences reflected in the flow field would enhance South Asia high in the higher troposphere(lower southwest vortex system),which might have an effect on the precipitation in Yangtze River basin.
