Acoustic-Gravity Waves Interacting with a Rectangular Trench [PDF]
International Journal of Geophysics, 2015 A mathematical solution of the two-dimensional linear problem of an acoustic-gravity wave interacting with a rectangular trench, in a compressible ocean, is presented. Expressions for the flow field on both sides of the trench are derived.

Nonlinear acoustic–gravity waves
Journal of Plasma Physics, 2009 AbstractPrevious results on nonlinear acoustic–gravity waves are reconsidered. It turns out that the mathematical techniques used are somewhat similar to those already adopted by the plasma physics community. Consequently, a future interaction between physicists in different fields, e.g. in meteorology and plasma physics, can be very fruitful.

Tsunami mitigation by resonant triad interaction with acoustic-gravity waves. [PDF]
Heliyon, 2017 Tsunamis have been responsible for the loss of almost a half million lives, widespread long lasting destruction, profound environmental effects, and global financial crisis, within the last two decades. The main tsunami properties that determine the size of impact at the shoreline are its wavelength and amplitude in the ocean.

Spectra of Acoustic-Gravity Waves in the Atmosphere with a Quasi-Isothermal Upper Layer
Atmosphere, 2021 In this paper, we study, in theoretical terms, the structure of the spectrum of acoustic-gravity waves (AGWs) in the nonisothermal atmosphere having asymptotically constant temperature at high altitudes.

A case study of the three-dimensional co-seismic ionospheric disturbance evolution [PDF]
Scientific ReportsThe total electron content is an integrated value of ionospheric electron density (Ne) along the satellite-receiver ray path; therefore, it cannot directly resolve ionospheric disturbances in the vertical direction. In this work, to better understand the

Electromagnetic oscillations of the Earth's upper atmosphere (review) [PDF]
Annales Geophysicae, 2010 A complete theory of low-frequency MHD oscillations of the Earth's weakly ionized ionosphere is formulated. Peculiarities of excitation and propagation of electromagnetic acoustic-gravity, MHD and planetary waves are considered in the Earth's ...

Brief communication "Seismic and acoustic-gravity signals from the source of the 2004 Indian Ocean Tsunami" [PDF]
Natural Hazards and Earth System Sciences, 2012 The great Sumatra-Andaman earthquake of 26 December 2004 caused seismic waves propagating through the solid Earth, tsunami waves propagating through the ocean and infrasound or acoustic-gravity waves propagating through the atmosphere.

Acoustic gravity waves: a computational approach [PDF]
Applied Numerical Mathematics, 1988 This paper discusses numerical solutions of a hyperbolic initial boundary value problem that arises from acoustic wave propagation in the atmosphere. Field equations are derived from the atmospheric fluid flow governed by the Euler equations. The resulting original problem is nonlinear.

Nonlinear interaction between acoustic gravity waves [PDF]
Annales Geophysicae, 1996 The resonant interaction between three acoustic gravity waves is considered. We improve on the results of previous authors and write the new coupling coefficients in a symmetric form. Particular attention is paid to the low-frequency limit.
