摘要
该文从描写β-平面近似下斜压Rossby波的准地转两层模式的方程组出发,建立了β-平面近似下斜压Rossby波线性稳定性的简单模型,当β看作纬度y的函数b(y)时,讨论斜压Rossby波的稳定性找到了它的控制参数p、q,应用常微分方程的稳定性理论对建立的模型进行定性分析,讨论其稳定性,并给出相应的相速限制.
In this thesis, the equations of a two-layer model of linear the baroclinic Rossby wave in the B -plane approximationare established. When the? ?y? is a function of latitude y ,we set up a simple model for the stability of the baroclinicRossbywave and find its control parameters p and q . And the stability theory of ordinary differential equations is used to analysisthe model、discuss the stability of it and solve the scope of phase velocity c of the stability of baroclinic Rossby wave.
