摘要
根据１８８０年以来的降水量观测记录及史料，建立了我国１１０°Ｅ以东３５个站１８８０～１９９６年完整的四季降水量序列．文中给出了建立序列的方法和四季降水量异常的空间分布特征．由ＲＥＯＦ分析表明，四季的特征向量十分相似．把１８８０～１９９６年四季的降水量级别合在一起作ＲＥＯＦ分析，得到６个降水变化集中区，为全年降水异常分析及预测提供了基本资料．
easonal precipitation series were constructed for 35 stations in East China from 1880 to 1996 on the basis of observational data and historical documents. Methodology of construction of the series and the spatial characteristics of seasonal precipitation anomalies were described. REOFs for each of the four seasons showed quite similar characters, so a united REOF analysis was carried out for four seasons together. Seasonal precipitation anomalies usually concentrated in six regions. It provided basic information of precipitation variability for diagnosis and forecast studies.
