1.Second, we add an nonlinear perturbation into the linear vorticity equation and get a new perturbation-value and perturbation-vorticity in a nonlinear equation.
在第二部分,作者将线性涡旋方程加入一个非线性扰动u(aξ)/(ay)-v(aξ)/(ax),进化轴对称涡旋扰动方程,将所有的分析建立在非线性涡旋扰动方程上,得出一个新的扰动流函数的无量纲值与扰动涡度。收藏指正
2.In this numerical scheme, the quasi-geostrophic barotropic equivalent vorticity equation is considered as a convetion-diffusion-reaction equation, which is easily treated by LBM. Under second-order accuracy, the quasi-geostrophic barotropic equivalent vorticity equationis recovered from the LB equation by Chapman-Enskog expansion.
该模型将准地转相当正压涡度方程作为一个平流—扩散—化学反应方程来加以处理,在整体二阶精度下,通过Chapman-Enskog展开成功将LB方程还原到了相当正压涡度方程。收藏指正
3.Using the upper air data for February 1956 some statistical behavior ofthe various eddy transfer term in the time-averaged vorticity equation for atwo-layer model is studied.

4.Three vortices,which happened over the Qinghai-Tibet Plateau in June of 1979,are estimated in this paper by using apparent heat source equation,apparent moist sink equation,perturbationenergy equations and vorticity equation. During the genesis and development process of the vortices,the vertical eddy transport of to-tal heat(sensible heat and latent heat)caused by cumulus and turbulence is very important.
