有界区域上的三维准地转无粘系统

The Inviscid 3D Quasi-Geostrophic System on Bounded Domains

Matthew Novack, Alexis Vasseur

摘要:

本文从有界圆柱域上的原始方程出发,给出了三维准地转无粘系统的形式推导。推导中的一个关键点是侧边界的处理和由此产生的边界条件,它强加于解决方案。据我们所知,这些边界条件是新的,并区分我们的模型与密切相关的模型,最近的研究对象。这些边界条件对于特定希尔伯特空间中的变分问题是自然的。我们构造解并证明了相应的变分问题的椭圆正则性定理,从而证明了(QG)的整体弱解的存在性。

英文摘要:

We present a formal derivation of the inviscid 3D 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).
