中文摘要: 使用1990—1991年5—6月的T42模式产品,采用样本正态化消空剔除手段,分别建立了中雨、大雨的消空方程y1、y2及大-暴雨判别方程y3。y1、y2减少空报,y3减少漏报。3个方程配套使用比用单个方程的效果好,成功界限指数有明显的提高,1992年试用效果较好。

Abstract:Moderate rain and heavy rain elimination equations y1, y2 and discriminant equation y3 of heavy rain are established with normalized sample rejection method T42 model output in May-June,1990-1991. The y1,y2 equations decreases the forecast "Occurrence" while the weather is no occurrence,y3 equation decreases the forecast "No"while the weather is occurrence. Conveyance using these three equations is more effective than using single one equation. "CSI"score increases obviously. Experimental forecast made in 1992 is better.
