摘要
较全面地比较了降水量、降水距平百分比及Ｇａｍｍａ分布百分位数三种降水量指标在降水研究中的优缺点。指出研究大范围的降水变化时，采用Ｇａｍｍａ分布百分位数的降水量指标比较合适。并以此为基础研究了中国及印度夏季降水与赤道东太平洋ＳＳＴ的关系。
Advantage and disadvantage of three rainfall indices were demonstrated. It indicates that the gamma distribution provides a good fit to precipitation data and enables precipitation amounts to be accurately expressed in terms of probability in the rainfall analysis of large scale region. The relationship between SST in east equatorial Pacific and precipitation in China and India was also studied on the basis of Gamma percentile series.
