| 摘 要： | 本文采用地形坐标系，设计了复杂地形热力和动力作用下中尺度天气系统对流云发展的二维数值模式，由模拟试验得出了与理论和观测事实完全一致的结果，即地形的动力热力抬升作用及充沛的水汽源和不稳定层结有利于对流云的发生发展。

| Abstract: | By employing a terrain following coordinote, a two-dimensional mesoscale model was developed for simulating some convective cloud processes under forcing of complex terrain and inhomogeneous heating. The results of numerical experiments, consistent with those of theoretical investigations and observations, show that topographically lifting and abundant moisture, as well as a layer of instability, are crucial for the generation and growth of a convective cloud. |

| Keywords: | mesoscale convective cloud numerical model terrain following coordinate |
