| Abstract: | Recently, using an eighth-order set of determinate, forced, dissipative, and nonlinear autonomous equations, which governs the dynamics of a quasi-geostrophic flow of the baroclinic atmosphere, Luo Zhexian and Ma Jingxian have provided the preliminary results concerning the chaotic forms in large scale atmospheric motion in the absence of orography and with variation of Coriolis parameter with latitudes during the summer half of the year.In this paper, orographic and p terms are introduced into the model used in reference 1],and the corresponding autonomous system changes from an eighth-order set to a twelfth one. The modified system indicate the results of numerical integrations that the chaotic large scale atmospheric motion can keep occurring both in the summer half and the winter helf and that the appearance of chaotic forms is connected with the break of the symmetry of flow patterns. |
