Through classification of 46 times heavy rain occurred in Yunnan province during the period of 1980_1990, it is found that the main impact systems of Yunnan rainstorm were resulted using the reanalysis data of NCEP/NCAR from 1989_1991, we discussed 11 times province wide cold front-shear line type rainstorm cases which most occurred in Yunnan by means of composite analysis.The results indicated the development characteristics of the atmosphere circulation, upper and lower jet or high wind line in troposphere before and after large-scale rainstorm occurred in Yunnan with cold front-shear line type circulation, the relationship between the development characteristics and the large-scale rainstorm, their commonness were found out in this work, we summarized the strong signal resulted in rainstorm in Yunnan for heavy rain storm forecast.
