摘　　要：本文应用欧洲中期预报中心1973～1987年3～5月500hPa高度场资料,着重讨论了长江中下游地区春季连阴雨过程中扰动动能谱特征和连阴雨形成过程中扰动动能谱的时空分布规律。By using ECMWF altitude field grid Point data at 500hPa from March to May of 1973-1987, the characteristics of disturbance kinetic energy spectrum during the persistent rainy period in spring and the rule of time-space distribution of disturbance kinetic energy spectrum during its forming Period in middle and lower reaches of Yangtze River are stressed .
