摘要
为了有效地模拟过山气流中可能出现的波破碎现象,本文采用高阶矩湍流闭合的二维大气中尺度数值模式,利用该模式模拟了有限高度的三种不同形状地形上的过山气流,讨论了地形形状对过山气流的非线性作用.
In this paper, in order that the possible waves' breaking in the airflow ovwr mountain is effectively simulated, the twodimensional atmospheric meso-scale numerical model is taken. With a higher-order turbulent closure. By this model, the airflows over finite-height mountains of three different shapes are simulated. And the non-linear effects of the shapes of the mountains on the airflows over the mountains are discussed.
