Based on the plateau monsoon index and plateau vortex data sets, contrast analysis in the plateau summer monsoon intensity, plateau vortex source, path, the frequency, intensity, the nature of the changes in temperature, area, duration and other characteristics, and the mechanism of the effects are discussed, the main results are: ①the plateau summer wind blowing lower by the main body, high plateau main blowing around. ②Plateau monsoon intensity is directly proportional to the generation frequency of the Plateau vortex, the number of eastward migration, and the generation frequency of the Plateau vortex in the east of the Plateau, and inversely proportional to the long life history of the Plateau vortex. ③In the initial stage, the intensity of the Plateau vortex is sensitive to the monsoon strength, and the strong latent heat area on the east side of the Plateau is conducive to the eastward movement of the Plateau vortex. Moreover, because of the strong sensible heat in the central and western parts of the Plateau in strong monsoon years, most of the high-intensity Plateau vortexes were born in the central and western parts of the Plateau, and the intensity of the Plateau vortexes was stronger at the beginning.
