摘要
通过分析北半球 50hPa平均环流场及其月际差、方差分布 ,得出 50hPa平均环流场以季节变化最显著 ,同时计算了我国东部华北、淮河、长江中下游、江南和华南等 5个区夏季降水指数与前期冬季 1 2～ 2月、春季 3～ 5月、同期 6～ 8月北半球 50hPa环流的相关 ,其中以与前期春季 3～ 5月
According to the analysis of 50 hPa mean circulation in the Northern Hemisphere(NH), it can be concluded that seasonal variation of 50 hPa is the most significant. In the meantime,the correlation coefficient is analyzed between summer rainfall index in East China(including 5 areas: North China area, Huaihe River area, middle low reaches of Yangzi River, areas south of Yangzi River and south China area) and 50 hPa mean circulation in previous winter,spring and in summer;and the relationship in previous spring is the most significant among the them.
