本文研究了f平面上两层模式中无粘空间增长斜压波的有限振幅行为。在弱非线性理论的框架下，发现非线性可以使流动稳定或不稳定。在前一种情况下，非线性波经历空间波动。在后一种情况下，存在流场的高频有限振幅亚临界失稳的可能性。这一研究与山地气旋生成问题有关。DOI：10.1111/j.2153-3490.1978.tb00865.x
Finite amplitude behavior of inviscid spatially growing baroclinic waves in a two-layer model on an f -plane is investigated. In the framework of the weakly nonlinear theory it is found that nonlinearity can stabilize or destabilize the flow. In the former case, the nonlinear wave experiences spatial vacillations. In the latter case, the possibility of high frequency finite amplitude subcritical destabilization of the flow field exists. The study is relevant to the problem of mountain-induced cyclogenesis.
