A Note on Geostrophic Adjustment and Gravity Wave in the Atmosphere

[摘要] The process of mutual adjustment of pressure and velocity distribution is discussed as an initial value problem, using a linearized barotropic or baroclinic model. It is shown that the velocity field is likely to be adjusted to the large scale pressure disturbance and the pressure field is likely to be adjusted to the small scale velocity disturbance. Pure geostrophic initial wind field will cause noticeable gravity wave, especially for very large scale motion with the peffect.The effect of heating and diffusion will also be mentioned briefly.
