摘要
利用鹤壁市 1986～ 1999年秋季高空图资料 ,确定了 4 8h和 2 4h中雨高空要素预报指标 ;利用 1995～2 0 0 0年Micaps数据格式的物理量场分析结果 ,确定了 2 4h中雨物理量预报指标。鹤壁市秋季中雨预报系统根据预报指标和人工神经元网络预报结果 ,对秋季降水进行逐级判别 ,综合做出预报结论。
The upper-air chart during 1986～1999 in fall has been traversed to select the forecast index. And the forecast index for 24h which comes from the physical factor also has been given by analyzing the data of Micaps during 1995～2000. Then the synthetic forecast can be done with the index and the output of artificial nerve network.
