摘　　要：一、引言山东半岛形似骆驼头楔入渤海和黄海之间,地处中纬度,深受海洋的影响,具有明显的季风气候特征。山东每年降水的多寡与国计民生关系很大,尤其夏季(6—8月)汛期降水量,占全年总降水量的60—70％,它在很大程度上影响全年降水的大局。虽然有些气象台,对山东局部地区降水做过不少分析研究工作,但就整个山东全省范围夏季降水分布的时空特征加以客观分析,并作出定量预报仍是十分必要的。In the paper the data of precipitation in Shandong Peninsola in summer during 1954—1985 were analyzed by using the empirical orthogonal function to find the space-time features of precipitation in the peninsola. The time cofficients of the modes in the precipitation forecasting equations were determined by using progressive regression method. The equations have been tested for 1986 and 1987, and the results are satisfactory.
