数字化卫星云图的短时降水预报方法

AN ESTIMATIVE METHOD OF VERY SHORTRANGE PRECIPITATION FORECASTING BY DIGITAL SATELLITE IMAGERY

摘要:

本方法利用日本GMS-3卫星的每3小时一次红外云图A分区图的数字化资料,根据云图灰级与降水的关系,并提取云团各种参数,对攻关课题预报区(A、B区)试作短时降水强度和位置的预报,取得良好的效果。

Abstract:

In this study, a method is proposed, using GMS-3 satellite digital data every three hours, for analyzing the relation between cloud grey degree and rainfall. Several parameters are thusobtained, from which rainfall intensity and locality in the "A, B" areas have been satisfactorily estimated in three hours.
