具有周期数据的垂直分层和垂直粘性消失的高度旋转流体

Highly rotating fluids with vertical stratification for periodic data and vanishing vertical viscosity

Stefano Scrobogna

摘要:

我们证明了没有垂直扩散的原始方程的整体适定(如果Rossby和Froude数足够小)在适当的Sobolev各向异性空间。此外,如果Rossby数和Froude数以相似的速率趋于零,则原始方程的整体解全局收敛于适当极限系统的整体解。所考虑的空间域必须属于一类环面,这是一般的,足以包括所有的非共振环面和许多共振环面以及。

英文摘要:

We prove that the primitive equations without vertical diffusivity are globally well-posed (if the Rossby and Froude number are sufficiently small) in suitable Sobolev anisotropic spaces. Moreover if the Rossby and Froude number tend to zero at a comparable rate the global solutions of the primitive equations converge globally to the global solutions of a suitable limit system. The space domain considered has to belong to a class of tori which is general enough to include all non-resonant tori and many resonant tori as well.
