摘要
从线性浅水方程组出发,在Arakawa A-E网格和Z网格上,从频率和群速方面讨论了这六种网格对大气中的两种重要的波动:惯性重力波和Rossby波的描述能力。结果表明:C、Z、E网格比其它网格产生的歪曲都要小。
Starting from the linear shallow-water equations and using Arakawa A-E and Z grids, a study is made of inertia-gravitational and Rossby waves in the six grids from the perspectives of frequency and group velocity. Results indicate that grids C, Z, and E thereof give smaller distortion compared to the others.
