Temporal and Spatial Distribution of Jianghuai Meiyu with EOF and REOF Analysis

ZHOU Hou-fu~1,CHEN Xiao-hong~2 (1.Anhui Meteorological Institute,Hefei 230031,China;2.Anhui Meteorological Station,Hefei 230031,China)  
Based on the data of Meiyu precipitation about 50 weather stations from 1960 to 2002,temporal and spatial distribution characteristics are analyzed with EOF and REOF methods.EOF analysis shows that the ratio of the front 3 eigenvectors with total square error is 88.9%,and the front 3 eigenvector fields present string distribution.The characteristic of each eigenvector field is different.REOF analysis manifests that Meiyu precipitation fields may be divided into 6 types and the change of rotated eigenvector field is little.The change of the first temporal coefficient is analogous with the change of average Meiyu precipitation on all stations.
