| Abstract: | A two-layer nonlinear primitive spectral model which includes Rayleigh friction, Newtonian cooling and the horizontal thermal diffusivity is used. The numerical simulation initiates from zonal meanflow field and carries out integration for 40 days.The results computed by this model show the effects ofthe standing planetary waves in winter.Particularly,the effects of different scale topography and ad-justable heat sources are considered. |
