Linear and nonlinear topographically generated Rossby waves
线性和非线性地形罗斯贝波

The stability and the solutions of linear and nonlinear topographically generated Rossby Waves were discussed by using a barotropic semi-geostrophic model. The criterion of nonlinear stability is the same as that of linear one. Under second order approximation both troughs and ridges of unstable isolated waves are formed in different locations, and for stable isolated waves only troughs are formed.
