摘要
本文在半地转近似下,用相角函数方法和常微分方程的相图分析,讨论了地形强迫下非线性Rossby波方程存在波度解的坡度条件和初始扰动条件。
Under semi-geostrophic approximation, the condition of topographic gradient and the initial perturbation in which the nonlinear equation describing Rossby waves possesses a wave solution were discussed by using the method introducing a phase angle function and analysizing the phase diagram determined by the ordinary differential equation.
