Abstract: Through the 24 cases in 1981-2012 census on the big flood process in the upper reaches of the Yangtze River, it was found that the influencing heavy precipitation weather systems are mainly: the moving eastward trough in balkhash lake, the stable trough in Baikal Lake and the cold trough in northeast. By using the method of statistics, diagnosis and synthetic analysis, the large-scale circulation background, the main influencing system and the mechanism to flood-causing precipitation were analyzed for these three weather types and their characteristics and differences were also summarized. The results showed that the characteristics of three types of flood and precipitation in each were not identical and the large-scale circulation background and the weather systems are also different. The subtropical high and middle-high latitude circulation anomaly on 500 hPa are the direct factors of heavy precipitation. Southwest vortex, cold front shear line and warm front shear line and cold air in different types of rainfall flood effect each are not identical, anomaly cyclonic wind field, water vapor transport direction and the vapor flux divergence convergence zone is closely related to the position of the heavy rain.

Key words: upper reaches of Yangtze River, big flood, type of balkhash lake moving eastward trough, type of Baikal Lake stable trough, type of northeast cold trough
