静力模式中水平分辨率与垂直分辨率的协调性问题

MATCHING BETWEEN THE HORIZONTAL AND VERTICAL RESOLUTION IN A HYDROSTATIC MODEL

本文将线性斜压适应方程组在最优三维网格C/CP下进行离散,讨论了不同的水平和垂直格距大小对解析解模拟的影响。结果表明:垂直格距为1 km量级时,水平格距应为100km量级;垂直格距为100 m量级时,水平格距应为10 km量级较好。

In this paper the linear baroclinic adjustment equations are discretized on best 3D C/CP grid, and the impact of different horizontal and vertical grid spacing on the simulation of the analytical solution is discussed, the result shows that the horizontal gridspacing should be 100 km （10km） when the vertical gridspacing is 1 km （100m）.
