In part I of this paper, we have discussed two problems: the general properties of two-dimensional baro-tropie motion and the evolution and structure of both Rossby wave packet and inertio-gravity wave packet, In this part, we shall continue our discussion. Third, normal modes and continuous spectra of both quasi-geostrophic and non-geostrophic models, their different behaviour, and the comparison of normal mode approach to the wave packet approach. Fourth, weakly nonlinear theory of interaction based on the analysis of eddy transports, A nonzonal basic flow as well as non-geostrophic model is also included in the consideration, The last, the fully nonlinear theory, making emphasis on the conditions for the maintenance of nonzonal disturbances and the conditions for their continuous and complete absorption by the zonal flow. A comparison of Rossby wave absorption to energy cascade in the two-dimensional turbulence is also given. 相似文献

在数值天气预告以及动力气象问题的研究中,人们常常需要求解如下型式的椭圆型线性偏微分方程其中μ为常数,也可以为零。虽然近年来初始方程已经得到广泛应用,但是如(1)型式的准地转涡度方程仍然在有些国家的业务预告中使用,特别是在一些动力气象的研究工作 相似文献
