Abstract: Based on FNL reanalysis data, the blackbody brightness (TBB) data from FY-2D meteorological satellite and multi-source fusion precipitation data, the WRF model was used to simulate a plateau vortex process from June 9 to 11, 2015. By comparing the differences between the control experiment and six groups of sensitivity experiments on the surface temperature of the Qinghai-Tibet Plateau, the influence of surface temperature on the generation location, structure, intensity and moving path of plateau vortex was studied, and the corresponding physical mechanism was discussed. The results show that the WRF model could well simulate the location, structure, moving path, circulation situation at 500 hPa height and precipitation at each stage of generation and development of the plateau vortex. The surface temperature of the Qinghai-Tibet Plateau had a certain influence on the intensity and precipitation of the plateau vortex, but had little effect on the generation and eastward movement of the plateau vortex. The influence of surface temperature on the plateau vortex was mainly achieved by affecting the surface sensible heat flux and surface latent heat flux.
