| 摘 要： | 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.
