摘要
本文用10年(1980—1989)夏季北半球500hPa候平均高度场资料进行遥相关分析,得到东亚太平洋型(EAP)和西欧型(WE)两种遥相关型及西亚-太平洋-大西洋振荡,并对高度场进行主成分分析(PCA),讨论了环流的时空分布特征.
In this paper, the teleconnections of the pentad mean of 500hPa height field during the Northern Hemisphere summer are analysed based on data of ten years (1980-1989). Two teleconnection patterns ( Eastern Asia/Pacific ( BAP) and Western Burasia( WE) pattern) and Western Asia/Pacific/Atlantic oscillation are found. The spatial and temporal distribution of the general circulation at 500hPa in summer is studied by the method of principal component analysis.
