| 摘 要： | 用数值模拟方法模拟了超级单体、单体和多单体雹云的流场和水凝结物场，并对其成雹规律进行了数值模拟研究。结果表明：可长成大雹的雹胚的初始出发区的位置主要由雹云的流场决定，而与雹胚的大小关系不明显；３种类型的雹云的成雹规律是相似的，超级单体之所以可以降大雹，主要是由于流型的稳定和长的生命期。

| Abstract: | Hydrometeor field in the super cell,multi cell and single cell hail storm are given using unmerical modeling.The growing process about the hailstone is analysed based on the simulation.The results show that the starting location of hail embryo which can growth to large hailstone is decided by the streamline field of hail storm,and the effect of hail embryo size on the formation of large hailstone is not remarkable.The generation processses of hailstione in three kinds of hail storm are similer each other.Owing to the stremline field is more stable and last longer time in the super cell hail storm,the larger hailstone can be gennerated in the super cell hail storm. |
