| 摘 要： | 使用T106数值预报产品建立了西北地区春季短期沙尘天气预报方程，提出对小概率事件的MOS预报方法的改良办法，结果表明，通过天气分型及天气事件等级划分的方法可以修正沙尘天气的概率分布，使得用MOS方法制作的沙尘天气的预报结果能够达到较好的效果。

| Abstract: | The T106 NWP Products were used to set up the short-range forecasting equations for regional sand-dust weather during spring in Northwest China. The MOS Method for weather incidents with little probability was improved. Ways of differentiating weather types and grading weather incidents may be used to modify the probability consistency of sand-dust weather, which can make the effect of forecasting sand-dust weather used the MOS Method better. |
