摘要
在局地热平衡情况下,将物理量先用韦伯函数展开,然后去掉相应分量的滤波方 法,讨论了简单热带海气耦合模型中不同形式扰动的作用和贡献,结果表明,在热带海气耦合 系统中,大气准定常 Rossby波和海洋 Rossby波对于耦合系统贡献较大,它们决定着耦合系统 与耦合扰动的性质,而大气准定常Kelvin波和海洋Kelvin波对于耦合系统贡献相对较小.
By using Fourier (Weber function) extension and filter methods, the functions of the different type of disturbances in a simple air-sea coupled model are investigated in the local thermal equilibrium case. The results show that the atmospheric quasi-stationary Rossby waves and the oceanic Rossby waves are very important to the coupled system, these waves control the character of the system. On the contrary, the atmospheric quasi--stationary Kelvin wave and the oceanic Kelvin wave are unimportant to the character of the coupled system.
