By using the monthly temperature in 160 stations of China and the NCEP/NCAR reanalysis data,the winter(November to March) temperature variations from 1951 to 2000 are studied with the empirical orthogonal function(EOF) analysis.

• 利用我国160个台站50年(1951~2000年)的月平均温度资料和NCEP/NCAR再分析资料,对我国从1951/1952~1999/2000共49个冬季(11月至次年3月平均)的气温进行经验正交函数(EOF)分解。
