摘要：
Computational dispersion properties of all vertically staggered grids, which are presently available, are analysed in terms
of frequency and group velocity components using the second-order centre difference scheme for a nonhydrostatic
anelastic approximation system with a general method. The inertial-gravitational waves with a horizontal scale of a
hundred-, ten- and one-kilometres are considered. The comparison analysis shows that the Charny-Phillips (CP) and
Lorenz grids are suitable for waves at all abovementioned horizontal scales, while the Lorenz time staggered and
Charny-Phillips time staggered grids are applicable only to waves with a horizontal scale less than 10 km.
The unstaggered (N) grid is not suitable for simulating waves at any horizontal scale. In an idealised flow numerical test,
the result on the CP grid has much less error than that on the N grid.
