| 摘 要： | 本文对正压模式中慢波的离散谱及其特征函数作了数值计算。结果发现，在低速线性缓变切变基流的情形下，正压原始方程中慢波可有离散谱存在。本文还给出了在该基流下算得的谱点和特征函数，并与准地转模式的计算结果进行了比较。

| Abstract: | In this paper discrete spectra and their characteristic functions of slow waves in barotropic models are calculated. It is found by numerical calculations that in the case of slowly varying low-speed basic flow with linear shear, there are discrete spectra of slow waves in the barotropic primitive model. Here spectra and their characteristic functions are given in the basic flow and they are checked against ones in the quasi-geostrophic model. |
