摘要
从非静力滞弹性方程组出发 ,从频率、群速和出现错误群速的垂直尺度范围等方面对现有的几种垂直网格进行比较讨论。结果表明 :在非静力模式中 ,CP网格和 LZ网格对惯性重力波的模拟较好。
In this paper, for the nonhydrostatic anelastic equations, in terms of the frequency and group velocity and the vertical scale ranges with group velocity of the wrong sign, the computational properties of the currently used vertical grids are analyzed. The results show that for a nonhydrostatic model, CP and LZ grids are more suitable to simulate the gravity inertial wave than the other grids.
