摘要
本文用经验正交函数展开的分析方法,确定了各种数值预报产品物理场中和对应时效的运城日降水量显著相关的物理量要素及关键区域,对关键区域的物理量场使用典型相关分析进行处理,得到了数量较少,而又能代表该关键区物理量分布状况主要信息的新因子,从而建立使用数值预报产品制作短期单站降水预报模式,进行预报效果较好。
The paper determines physical essential factors and key region of daily rainfall significance correlation between a variety of NWP product physical value field and correspondent verdict in Yuncheng by means of EOF analysis. It processed physical fields in key region by using typical correlation analysis and obtained less new factors which can represent main information of physical value distribution in the key region, and then set up a short range precipitation forecast model for solo station in application of NWP products. The model has worked and been better.
