长江中游地区对流云团的卫星云图统计特征和预报流程

STATISTICAL CHARACTERISTICS AND FORECASTING FLOW OF CONVECTIVE CLOUD CLUSTERS IN THE SATELLITE PICTURES OVER THE MIDDLE REACHES OF THE CHANGJIANG RIVER

摘要:

本文使用1979-1986年6-8月中旬的静止卫星云图资料,统计分析了影响A、B区对流云团的初生位置、移动、持续时间、云团与天气尺度云系的关系等,提出了作0-6小时暴雨预报的流程。

Abstract:

By use of the geostationary satellite pictures in June-August, 1979-1986, the formation, initial location, track and duratioa of convective cloud clusters over the middle reaches of the Changjiang River, on the one hand, and the relationship between the cloud clusters and the synoptic-scale cloud system, on the other, are statistically analyzed. The 0-6 hr rainstorm forecasting flow diagram is suggested.
