文摘In this paper,a three-dimensional EOF technique is used to analyze the precipitation and its anomaly over whole China and sanely selected regions,i.e.the Changjiang Valley,the Huanghe Valley and the South part of China in last decades.The structural characteristics of spacial distribution,seasonal and interannual variation are revealed.As a better technique than 2-D EOF,the 3-D EOF alse provides a way to expose interac- tions between temporal and spacial variations.
