This thesis aims to study the nonlinear stability of quasi-geostrophic flow. This paper is divided into three parts.
本文旨在对地球流体准地转运动的非线性稳定性问题进行研究，全文分为三个部分。

A simple LB model is present to numerically solve the quasi-geostrophic barotropic equivalent vorticity equation at first.
首先，本文建立了一个求解准地转相当正压涡度方程的LB模型。

Using a low order, two-layer baroclinic quasi-geostrophic model, a nonlinear system including the interaction between a thermal forced wave, a transient wave and zonal flow is studied.
