摘要

本文分析了北半球34年月平均500hPa高度异常的月-月相关特征。结果表明,北半球高度异常的总体相关是大于零的,在副热带相关系数可达0.3以上,在中高纬度约为0.0-0.2。亚洲和北美地区中高纬的环流异常相关还显示出明显的季节变化特征,在冬夏季有最强的相关,春秋季相关最弱。

Abstract

The characteristics of month-to-month correlation of the monthly mean 500 hPa height anomalies for 34 years in Northern Hemisphere are analysed. It is shown that the correlation of height anomalies in Northern Hemisphere is positive and the value is more than 0.3 in subtropics and a lower value is about 0.0-0.3 in midlatitudes. The correlation of circulation anomalies in midlatitudes over the Asia and North America shows also clear seasonal variations,with maxima in winter and summer and minima in spring and autumn.
