| Abstract: | 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. |
