| 摘 要： | 本文从含Ekman摩擦的非线性两层斜压模式出发,应用Serrin-Joseph的能量方法,按变分原理,分别用扰动总能量、总位涡拟能和两者的线性组合导得了非纬向基流的非线性斜压稳定性判据。并和线性判据作了比较。

| Abstract: | From a two-level nonlinear baroclinic model including frictional dissipation, using Serrin-Joseph's energy method, by means of the variational principle,the nonlinear baroclinic stability criterions of nonzonal flows with the total energy, and total enstrophy, the linear combination of above two quantities respectively are found, and these criterions are compared with the linear stability criterion. |
