Abstract: To find out the relationship between long distance typhoon and rainstorm in Chongqing, the authors analyzed 57 typhoon rainstorm cases in Chongqing under the typhoon background using statistical analysis respectively from the monthly and interannual variations. The authors pointed out that the typhoon path which was closely related with rainstorm in Chongqing was west path and north path. The result showed that: the typhoon rainstorms in Chongqing first appeared in mid-April, and the latest was in early October, most of the typhoon rainstorms were in June to August, the number of long distance typhoon rainstorms appeared most in July. Through synthetic analysis, the authors found out that the circumfluent background between regional typhoon rainstorm and typhoon rainstorm which had not reached regional rainstorm had significant differences; there were 4 flow patterns: east high west low, west wind inverted trough saddle shaped flow pattern, midlatitude low pressure flow and straight west wind by contrastive analysis on synthetic typhoon flow.
