In this paper, hy generalizing the linear convection current model and using "partical method", a nonlinear convection current model taking into consideration the atmospheric stratification, local heating and viscosity has,been set up using the theory of the flow stability, bifurcation and catastrophe. It is shown that(A) Under the condition of the nonlinear stratification the stratified stability depends on the linear stratified parameter μ and the strength parameter b which indicates the nonlinear stratifixation. As the parameter μ changes sign from negative to positive, the subcritical and supercritical bifurcations take place in b > 0 and & < 0 respectively. It represents that due to the nonlinear stratification the stability can be changed at a certain height.(B) Under the condition of the nonlinear stratification the change of the heating strength can result in the catastrophe of the stratified state.(C) Under the condition of the linear friction, the change of the linear stratification can lead to saddlenode bifurcation, then the criterion of the Benard convection current is derived. If we consider the shear of the wind, the Hopf bifurcation and Miles the orem can be obtained.

本文推广气块法所建立的线性对流模型,利用了流动稳定性及分岔和突变理论,建立了包含层结、局地加热及阻力等因子的非线性对流模型。研究指出: 1.在非线性层结的条件下,层结稳定性决定于线性层结参数μ(μ=-N~2,N为Brunt-频率)和表征非线性层结的强度参数b。在b>0时,参数μ由负到正会发生亚临界分岔,它表明即便是线性稳定层结(μ<0),但由于非线性层结的作用,在一定高度上会出现非线性层结不稳定;在b<0时,参数μ由负到正会发生超临界分岔,它表明即便是线性不稳定层结(μ>0),但由于非线性层结的作用,在一定高度上会出现非线性层结稳定。 2.在非线性层结的条件下,局地加热强度α的变化会引起层结状态的突变。 3.在线性阻尼的条件下,线性层结的变化会发生鞍一结点分岔,由此可导得Benard对流判据;加入风速切变的影响后,其变化会发生Hopf分岔,并可得到重力内波稳定的Miles判据。

In this paper, based on the assumption of the geostrophic wind with linear horizontal and vertical shear, a nonlinear ordinary differential equation is constructed considering the atmospheric stratification with linear and nonlinear vertical shear. Furthermore, the instability criteria of nonlinear strutification symmetric motion have been obtained by discussing the convexity of Hamilton's function, and the catastrophe condition of nonlinear stratification symmetric motion is discussed.
