摘要
本文应用OLR资料以及ECMWF风场资料分析了长江中下游春季连阴雨过程的热带和副热带环流系统的特征及与连晴过程的差异。同时,还进一步研究了春季东半球热带和副热带地区低频振荡的基本特征及传播规律,得出了可能产生长江中下游连阴雨的低频振荡的背景事实。
In this Paper, Outgoing Longwave Radiation (OLR) data of NOAA and wind field data from ECMWF are used to investigate circulation feature in tropics and subtropics during the persistent rainy days in the middle and lower reaches of Changjiang River in spring. Fur thermore, the low frequency oscillation feature and propagation rule in the tropics and sabtropics of eastern have been researched and obtained some background indeed of low frequency oscillation which probably bring about the persistent rainy days in the middle and lower reaches of Chang Jiang River in spring.
