| 摘 要： | 采用主分量分析法（PCA）对中国东南部（105°—122°E，19°—33°N）90个测站（除台湾省外）1954—1989年逐年1，4，7，10月降水量标准化资料进行分解，得到各种异常降水型及相应的时变序列；对最为典型的3种异常降水型的空间分布特点、时变特征、逐年分型情况进行了分析，并探讨了各月各异常降水型变化与赤道东太平洋海面温度变化间的可能关系及它们在厄尔尼诺年份（或次年）的一些特点和规律。

| Abstract: | Based on the standardized data of monthly precipitahon in Jan., Apr., Jul.and Oct. for the years from 1954 to 1989 at 90 stations in the Southeast China, threetypical anornalous precipitahon pattems are abtained by way of principal componentanalysis. The characteristics of their space distribution, Periodic change and lineartrend are analyzed. The possible relation betWeen each anomalous pattem in themonths mentioned above and the SST in the East Equatorial Pacific is also analyzedand the characteristics of each pattern in the years and the next years of the El Nifioevents are discussed. |
