摘　　要：用奇异值分解的方法逐月分析了华南汛期(4～9月)降水与南海地区OLR变化的关系,并用合成分析的方法对OLR异常年份的降水进行对比分析,结果表明两者确实有一定的相关关系,后汛期(特别是7、8月)两者的相关程度比前汛期大,但每个月的情况各有不同。The relationship between the variations of OLR over South China sea and the precipitation in rainy seasons in South China are investigated by means of SVD(Singular Value Decomposition), and the precipitation in anomalous OLR months are compared. Results show that they do have relationship and they are more closely correlated in the second rainy season(especially in July and August), and the situations are different in every month.
