We have previously studied how acoustic waves generated by strong thunderstorms and ocean waves propagate into the thermosphere and heat it. We revisit this investigation to clarify the physical processes contributing to the overall net heating. Our conclusions are based on numerical simulations of wave propagation using a full-wave model that solves the complete linearized equations of continuity, momentum, and energy for a compressible, viscous, and thermally conducting atmosphere with arbitrary altitude variations in thermal structure. It is found that acoustic waves heat the thermosphere through effects of molecular dissipation, sensible heat flux divergence, and Eulerian drift work. Only wave-induced pressure gradient work acts to cool the thermosphere. The net effect of all these processes is acoustic wave heating of the thermosphere at all heights. These physical processes act differently for gravity waves; in particular, gravity wave sensible heat flux divergence can cool the thermosphere. Acoustic waves generated by vigorous convection and storms in outer planet atmospheres could also contribute to the heating of these atmospheres.
