摘要
用 EOF方法分解我国近 44a的旬降水场 ,得知 :我国旬降水的 6种主要空间型出现的集中时段各不相同 ,各型均以年际和年内的短周期变化为主 ,且有各自的长期变化趋势。 EOF展开空间型的时间系数间存在显著的统计相关。
Based on dekad precipitation in the last 44 years,the method of EOF is employed to study the spatial and temporal features of rainfall in China. The results show that the first six spatial patterns describe some major features of dekad precipitation such as different concentrative time intervals of each pattern,characteristics of annual and inter-annual oscillation and long-term tendency of variation. The statistic correlations between time coefficients are significant.
