用HLAFS物理量分析1997年6月7～9日暴雨过程

Analysis of torrential rain from 7th～9th,june,1997 with physical variables fields of HLAFS

利用1°×1°的HLAFS数值预报产品，分析了我省1997年6月7～9日暴雨过程0h部分物理量的分布特征。通过物理量0h实时场与12～48h预报场的对比分析，指出预报场的误差及对这次暴雨过程预报有较好指示意义的物理量场。

In this paper, the real - time synoptic weather background and the distributive features of some physical quantities from '0' hour forecast fields during the torrential rain process from 7 to 9 of June 1997 are analyzed by use of HLAFS numerical forecast products(grids 1° * 1°). By comparing '0' hour real - time fields with those of 12~48 hour forecast, We present the errors of numerical forecast fields and give some fields of physical quantities which give good indications of the torrential rain process.
