摘要: 本文应用群分析的方法,对1951-1980年9月分10°E-165°W,10°N-70°N范围内的500毫巴环流形势场进行分类,以便了解不同类型的大气环流特征以及在不同大气环流型影响下,丹江口水库区流域降水和平均入库流量发生变化的情况.进而为水库的调度方案的编制和洪水预报提供气候学依据.

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
