Numerical Experiments with the Impact of the Plateau on the Characteristic Spatial Structure and Moving Speed of Planetary Waves

The impact of the Qinghai-Xizang Plateau as a huge orography on the spatial structure of moving planetary waves is investigated using the 12-layer primitive equation model with p-σincorporated corrdinate. The results show that the Plateau’s dynamic effect is highly correlated with its characteristic configuration. The plateau as a noteworthy factor may result in a complicated change of the spatial structure of moving planetary waves, that is to lead to the phase difference between two waves on the north- and south-facing slope, wave speed change and deformation of the spatial structure
