, 2017 This chapter deals with the underlying mathematics of atmospheric waves. Gravity waves occur between any stable layers of fluids that differ in density. When the fluid boundary is disturbed, buoyancy forces try to restore the equilibrium. The fluid returns to its original shape and overshoots before oscillations finally set in that propagate as waves ...

Seismic Waves from Atmospheric Sources and Atmospheric/Ionospheric Signatures of Seismic Waves
, 2009 The sounding of the ionosphere with GPS, Doppler sounder, or Radar allows the detection of acoustic waves or gravity waves generated by quakes or tsunami at teleseismic distances, in addition to the acoustic waves generated by the seismic source near the epicenter.

On the propagation of waves in the atmosphere [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2021 The leading-order equations governing the unsteady dynamics of large-scale atmospheric motions are derived, via a systematic asymptotic approach based on the thin-shell approximation applied to the ellipsoidal model of the Earth’s ...

Wave heating of the solar atmosphere [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015 Magnetic waves are a relevant component in the dynamics of the solar atmosphere. Their significance has increased because of their potential as a remote diagnostic tool and their presumed contribution to plasma heating processes. We discuss our current understanding of coronal heating by magnetic waves, based on recent observational evidence and ...

On the propagation of nonlinear waves in the atmosphere
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2022 Starting from the general equations of fluid dynamics that describe the atmosphere, and using asymptotic methods, we present the derivation of the leading-order equations for nonlinear wave propagation in the troposphere. The only simplifying assumption is that the flow in the atmosphere exists in a thin shell over a sphere.
