Abstract: In this Paper Clustering analysis was used to classify the 500 mb circualtion fields in September at 10°E-165.°w and 10°N-70°N in 1951-1980, for the purpose of understanding the characteristics of atmospheric circulation in different patterns, the variations of the precipitation in the Dan-Jiang-Kou reservoir basin and the mean discharge of the entering flow under the influences of different patterns.This paper provided too the climatic background for the rational dispatch and flood control of the reservoir to make the maximum benefit of it
