Kato, S., 1966: The response of an unbounded atmosphere to point disturbances. I. Time-harmonic disturbances. Astrophys. J., 143, 893-903, doi:10.1086/148564.

The response of an unbounded and isothermal atmosphere to time-harmonic point disturbances of force is studied. The exact solution is obtained in the whole frequency range of disturbances, including the frequency ranges of acoustic waves, trapped oscillations, and gravity waves. For disturbances whose frequencies are Just above the lower characteristic frequency of the atmosphere, ω2( = [γ - 1]1/2 g/c), the atmosphere responds very efficiently, especially to vertically oscillating disturbances. Furthermore the response is sharply restricted to regions above the source, and the velocity field in that region consists' mainly of a vertical one. These characteristics of the response persist into the frequency range of acoustic waves if the atmosphere is sufficiently stable to convection.
