摘要
本文应用1980年至1987年3—5月欧洲中期天气预报中心的风场格点资料,通过对流函数ψ场、势函数X场的计算和分析,得出了长江中下游地区春季连阴雨、连晴天气过程中850hPa高度层的流场、散度场特征,并重点讨论了热带环流系统的影响。
By using ECMWF wind field grid point data at 850hPa from March to May of 1980-1987 stream functiou and velocity potential fields are calculated. Through detailed analysis and comparison, the characteristics of the fields during the period of persistent rainy and or sunny days in spring in middle and lower reaches of Yangtze River are found. And the influence of tropical circulation system is also stressed.
