大气中非线性Kelvin波的一个特殊形态

通过对非线性方程组的求解和讨论，指出：非线性Ｋｅｌｖｉｎ波与线性波相比，在扰动的水平结构和时间演变上都存在着显著的差异；在波动的传播方式上也较线性情形复杂。与层结大气中的正压模态有关的波动亦有与上述类似的特征。

A SPECIAL FORM OF NONLINEAR KELVIN WAVE IN THE ATMOSPHERE

The present paper has obtained a special solution of the system of nonlinear equations. Results show that there exists obvious difference in horizontal structure and time variation of perturbation between nonlinear and linear Kelvin waves. Compared with the linear Kelvin wave,the nonlinear Kelvin wave is much more complicated in the way of propagation. Waves concerned with the barotropic mode have the similar features to those mentioned above.
