我们从有界圆柱区域上的原始方程出发,给出了无粘性三维准地转系统(QG)的形式推导。推导过程中的一个关键点是侧边界的处理以及由此产生的边界条件对解的影响。据我们所知,这些边界条件是新的,并将我们的模型与最近研究的密切相关的模型区分开来。对于特定的希尔伯特空间中的变分问题,这些边界条件是自然的。我们构造了解并证明了与变分问题相对应的椭圆正则性定理,从而证明了QG整体弱解的存在性。
We present a formal derivation of the inviscid three dimensional quasi-geostrophic system (QG) from primitive equations on a bounded, cylindrical domain. A key point in the derivation is the treatment of the lateral boundary and the resulting boundary conditions it imposes on solutions. To our knowledge, these boundary conditions are new and differentiate our model from closely related models which have been the object of recent study. These boundary conditions are natural for a variational problem in a particular Hilbert space. We construct solutions and prove an elliptic regularity theorem corresponding to the variational problem, allowing us to show the existence of global weak solutions to QG.
