| 摘 要： | 为了对发生于2008年9月23日成都的强对流天气有更多的认识,利用三维对流云模式对其进行数值模拟研究.结果表明:该模式可以较好地模拟出强对流天气各主要的宏观发展阶段的特征,以及云中水成物固、液相粒子转化的微观特征;强上升气流与充足的水汽含量是系统中强对流单体的旺盛发展的基本条件;在该强对流天气过程中,固态水成物粒子的累积和融化对于降水的贡献都是十分明显的. |

| Abstract: | In order to study more about the strong convective weather occurred in Chengdu on Sep.23rd of 2008,it is simulated by utilizing three-dimension convective cloud model.The results are as follows.The model can simulate macroscopic characteristics of strong convective weather in major developing sections,as well as microscopic ones of evolution of hydrometeor particles in cloud rather well.The strong updraft and sufficient vapor are essential conditions for the developing convective cells.Accumulating and melting of solid hydrometeor particles distinctly contribute to the precipitation. |
