| 摘 要： | 本文主要对基于WRF模式的快速同化系统（RUC）中使用的积云对流参数化方案进行简单介绍,并对不同积云对流参数化方案进行了典型个例降水预报的对比试验和检验。结果表明,总体预报效果以KF和GD方案较好,具体表现在雨区分布及大暴雨中心强度,对流降水对总降水贡献,在中低层流场高低值系统分布,以及冷空气活动引起的变温正负中心强度及位置,KF和GD方案模拟结果可以较好地反映观测实况,TS评分结果也表明KF和GD方案在小级别降水预报中占有优势。

| Abstract: | In this paper,the cumulus parameterization schemes used in WRF model which had been published was described simply,the precipitation forecast between different schemes was experimented contrastively and verified.The results showed that the KF and GD scheme were better than others,the specific performance in rainfall distribution and heavy rainfall intensity,the contribution of convection rainfall to total precipitation,the distribution about high and low system in middle and low layer,and the cold air activ... |
