Integrated analysis of 7 times heavy rain in Yunnan from July 19 to August 2 based on actual observation weather datum and satellite cloud atlas and Doppler radar image. The results show that: high-low southwest jet stream is important effect system. The maintenance of southwest jet stream provides water vapor, momentum, fast transfer of unstable energy for the lasting heavy rain. The further configuration of plateau shear line and southwest jet stream is necessarily condition about 7 times heavy rain. The lasting heavy rain appeared on big value region of 500hPa vapour flux and vapour flux divergence. The shear cloud band and subtropical high cloud band crossed and confluenced in Yunnan on the satellite cloud atlas. The maintenance and intensification of shear cloud hand and periphery cloud band of subtropical high correspond quite well to heavy rain falling region and cloud band distribution.
