不同因子处理方法对广西MOS方程降水预报准确率影响的试验

利用１９９５—１９９７年Ｔ１０６输出产品，以相同的数学回归模型对各种不同的因子处理方法生成的预报因子做广西８９站的降水预报准确率对比试验，结果表明预报因子的选取与准确率关系极大。这也说明了选取合理的、有物理意义的因子是建立ＭＯＳ降水预报方程成功与否的关键。

Examination of the Effect of Different Factor Treatment on the Accuracy of MOS Equation Precipitation Forecast in Guangxi

By adopting the T106 output product during 1995 ~ 1997, a contrast test on the accura- cy of precipitation forecast by different factor treatment in 89 meteorology stations of Guangxi is carried out in the same mathematical regression model. The examination result shows that selec- tion of forecast factor is closely related to the forecast accuracy, and that the selection of rational and physically meaningful factors is a key step to set up MOS precipitation forecast equation.
