摘　　要：用Wallace的一点相关方法,研究了我国季、月降水场的空间遥相关结构,得到季月降水遥相关型。给出了遥相关型的中心测站和相应的遥相关系数。讨论了它们的季节变化特征。此外,研究了我国6、7月份早涝的前朗降水特征。指出,上年11月、当年1月的降水场与6、7月降水场关系密切。长江中下游测站的1月降水量的隔季相关非常明显。Studies are made of the spatial telecoanecticn structure of the mcnthly precipitation field in different seasons in China by using Wallace one-point correlation, thus resulting in the teleco nnection patternslof seasonal and monthly precipitation. The central stations having the telecorrelation patterns and the corresponding teleconnec-tion coefficients are given together with a discussion of the features of their seasonal changes. In addition, analysis of the precipitation characteristics at the early stage of June-July drought/flood in China shows that the precipitation field in November of the previous year and January is closely related to that in June-July and the January rainfall at the stations ia the middle and lower reaches of the Changjiang River has a significant alternate-seasonal teleronnection.
