地形强迫下的Rossby波和Pseudo—Rossby波

本文在半地转近似下,用相角函数和常微分方程相图分析的方法,讨论了地形强迫下非线性Rossby波方程中存在Rossby波和Pseudo-Rossby波解的坡陡条件和初始场扰动条件.

The Rossby Waves and the Pseudo - Rossby Waves forced by topography

Under semi-geostrophic approximation, the parametric conditions and the initial pcrturbative comditions in which the nonlinear equation des cr ib ing Rossby waves possesses a wave solution were discussed by the me th -od introducing a phase angle function and analysizing the phase graph determined by the. ordinary differential equation;The effect of topographic gradients on wave solutions was investigated as well.
