Two Major Modes of the Wintertime Precipitation over China
我国冬季降水年际变化的主模态分析

Based on the observed precipitation data from 160 China stations,the NCEP/NCAR reanalysis dataset and the sea surface temperature(SST) dataset from the Met Office Hadley Centre,this study investigates two major modes of wintertime precipitation over China through empirical orthogonal function(EOF) method and associated atmospheric circulation and SST through linear regression method.It reveals that the first two EOF modes account for 49.6% and 17.3% of the total variance,respectively,and can be well separat...
