暴雨数值预报中的初值试验

本文介绍使用五层原始方程有限区域降水预报模式进行汛期暴雨数值预报试验时,引进的新的初值方案。给出了用新初值方案计算的个例和1986年汛期实际预报试验的结果。与其它方案计算结果的比较表明,认真改进初值有助于改进暴雨预报,新的初值方案可以满足暴雨预报业务试验的要求。

The initialization test in numerical prediction of heavy rain

This paper represents a new initialization program and some results of a number of model runs for cases. The samples of less successful prediction from historical cases were computed once again using the new program. The results are much better than that of previous. Some progress have been arrived by introducting this new program into practical prediction experiments during the rainy season 1986.
