| 摘 要： | 在要用数值预报产品制作温度，降水客观预报时，一种常见的方法是对数值预报产品格点因子进行平滑处理，以利于过滤噪声，为了确定对格点因子进行平滑处理与非平滑处理优劣，采用1995－1997年6－9月的国家气象中心T106数值预报产品资料，分别建立了这两种方法的山东省各测站1－5天日极端温度，降水量MOS预报方程，并对1999年7－9月的预报结果进行了对比检验，结果表明，非平滑处理优于平滑处理的预报效果。

| Abstract: | Making objective prediction of temperature and precipitation with numeri cal weather prediction products,a common method is used in smoothing the numeric al weather prediction product factors so as to filtrate noise.To compare smoothi ng factors with non-smoothing ones,MOS forecast equations about daily extreme t emperature and rainfall in 1—5 days at various Shandong weather stations were s et up,with the two methods respectively and the use of T106 numerical weather pr ediction product data of during Jun.—Sep.from 1995 to 1997.The two prediction r esults during Jul.—Sep.in 1999 were tested.It shows that forecast effect of non -smoothness management is superior to that of the smoothness management. |
