对称不稳定理论及其应用问题(二)非线性理论

A Review of the Symmetric Instability Theory and Its Application—PartⅡ: Non-linear Theory

摘要: 文章对对称不稳定理论及其应用的现状进行了全面的评述。主要讨论非线性理论，这包括非线性对称不稳定的一般研究方法（能量积分法，奇异摄动法，气块质点法，分岔和突变理论，数值试验），二维定常非线性对称环流的稳定性等问题。最后讨论了线性理论和非线性理论在实际应用方面的差异。

Abstract: The present paper has comprehensively reviewed the state of symmetric instability theory and its application to mesoscale meteorology. Here is its part 2 which mainly deals with the nonlinear theory. It includes the general approach to study of nonlinear symmetric instability and the stability of the steady, two-dimensional non-linear symmetric circulation. Finally, the differences in application between the non-linear and linear theories are discussed
