中文摘要:本文对文献[1]中的积云数值模式增加了冰雹发生项。在DJS——6机上调试后,将江淮地区暖半年内降雹和暴雨各4次过程发生日的探空等资料分别输入该云模式,在其他条件完全相同情况下进行数值试验,取得了与实况相近的降雹或暴雨的模拟结果。证明本模式对降雹过程、暴雨过程有较好的分辨能力,且模式云的宏、微观结构及其演变特征与自然云亦基本相似。因此,用本模式估算和分析江淮地区暖半年强降水是可行的。
 
A PRELIMINARY EXPERIMENTAL CUMULUS MODEL FOR FORECASTING RAINSTORM AND HAILSTORM
Abstract:A term for hailstorm development is added to the numerical cumulus model presented in an earlier paper [1]. Radiosonde and other data of 4 cases of rainstorms and hailstorms respectively, all of which occur over the ChangJiang(Yangtze)-Huaihe Valley in the warm months,are fed into the model,which is operated on a DJS-6 computer. The computed results approach what are observed in reality. The experiment shows that the model is fairly successful in identifying hails and the simulated macro-and micro-structure of the cumulus and its development process resembles those of the natural cloud.
