摘要
本文应用1975—1983年OLR资料以及1980—1983年ECMWF7层资料,分析了长江中卞游春季连阴雨过程中热带和副热带系统的基本特征及与连晴过程的差异,着重讨论了厄尔尼诺年热带和副热带异常的环流背景以及对长江中下游过渡季节持续降水的影响,揭示了一些有意义的事实。
In this paper, outgoing longwave radiation (OLR) data from 1975 to 1983 and ECMWF seven layers data from 1980 to 1983 are used to investigate the basic features of the tropical and the subtropical system in the steady rain processes over the middle-lower reaches of the Changjiang River in spring and their difference with those in the steadily clear processes. Furthermore,the anomalous circulation background over the tropics and the subtropics in the El-Nino years and its effect on the steady rain over the middle-lower reaches of the Changjiang River in the tran-sition seasons are discussed emphatically, and some significant facts are revealed.
