| 摘 要： | 本文利用每小时红外增强显示（EIR）和红外（IR）云图，6小时降水量及常规气象资料，对1991年6月12—14日和7月6—7日江淮地区大暴雨过程进行分析，给出了梅雨锋上中尺度对流云团活动的特征（包括生成源地、生命史、移向移速及对流云团生成的几种形式）；讨论了中低纬度云系相互作用对暴雨云团发生、发展的重要性；最后概括出中尺度暴雨云团发生、发展的云模型和概念模型。

| Abstract: | By using the hourly GMS infrared imagery and conventional meteorological data,ananalysis of the meso-convective cloud clusters in the Mei-yu front during the rainstormperiod in the reaches of Yangtze and Huaihe Rivers in 1991 is made.It includes the basiccharacteristics of the meso-convective cloud clusters in the Mei-yu front (such as,source,life cycle,direction and velocity of their movements,and their types of genesisetc.).The importance of the environmental conditions,especially the interaction be-tween the cloud systems of middle and low latitudes for the formation of the meso-con-vective clound clusters is discussed.Finally,a cloud model and a conceptual model forthe development of meso-convective cloud clusters in the Mei-yu front is given. |
