夏季东亚季风区500 hPa月环流异常及与我国降水关系的向量EOF分析
Vector EOF Expansion of Summer Monthly Anomalous Wind Fields
at 500 hPa over East Asia Relation to Rainfall over China
摘要
Abstract
Using the summer monthly mean wind field and the rainfall data in China from 1980 to 1997, the spatial and temporal variation characteristics of main anomalous modes of wind field have been studied by the method of vector EOF expansion. It has been found that there exists close relation ship between the main modes and summer rainfall in China, especially EOF1 and EOF2. The time coefficients of main modes display feature of multiple time scale, among them the 3～6 year fluctuations
are obvious.
