摘要
本文用二层非线性原始方程谱模式，并在方程中考虑了Rayleigh摩擦、Newton冷却和温度水平扩散，在伟向均匀的初始场下，积分40天，分别模拟了地形、热源单独作用和共同作用对冬季定常行星波形成的影响、尤其考虑了不同尺度地形和非定常热源的影响．
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.
