从正确模拟垂直波传播和消除离散模型中的任何计算模式的角度，研究了一种在垂直网格点上分布变量的合适方法。基于上述考虑，利用Arakawa守恒格式推导出了一种垂直差分格式。通过对内波进行适当的模拟和精确的静水关系，消除了该方案中的一些任意因素。
A suitable way of distributing variables over the vertical grid points is studied from the standpoint of proper simulation of vertical wave propagations as well as eliminating any computational modes in a discrete model. Based on the above considerations, a vertical differencing scheme is derived by use of Arakawa's conserving scheme. Some arbitrary factors in that scheme are eliminated by requiring a proper simulation of internal waves and accurate hydrostatic relations.
