Low-frequency Internal Gravity Waves Are Pseudo-incompressible
Starting from the fully compressible fluid equations in a plane-parallel atmosphere, we demonstrate that linear internal gravity waves are naturally pseudo-incompressible in the limit that the wave frequency ω is much less than that of surface gravity waves, i.e., $\omega \ll \sqrt{{{gk}}_{h}}$ , wh...
