Instabilities in internal gravity waves
Mathematics in Engineering, 2022 <abstract><p>Internal gravity waves are propagating disturbances in stably stratified fluids, and can transport momentum and energy over large spatial extents. From a fundamental viewpoint, internal waves are interesting due to the nature of their dispersion relation, and their linear dynamics are reasonably well-understood.

On the Frequency of Internal Gravity Waves in the Atmosphere: Comparing Theory with Observations
AtmosphereThis paper is devoted to the dynamics of the propagation of non-planetary scale internal gravity waves (IGWs) in the stratified atmosphere. We consider the system of equations describing internal gravity waves in three approximations: (1) the ...

Scattering of internal gravity waves
, 2011 Internal gravity waves play a fundamental role in the dynamics of stably stratified regions of the atmosphere and ocean. In addition to the radiation of momentum and energy remote from generation sites, internal waves drive vertical transport of heat and mass through the ocean by wave breaking and the mixing subsequently produced.

The Astrophysical Journal, 2023 The study of Li phenomena in red clump (RC) stars can give us a deeper understanding of the structure and evolution of stars. Chanamé et al. explained the RC Li abundance distributions naturally using only standard post-main-sequence (MS) Li evolution ...

Heating and cooling of the thermosphere by internal gravity waves [PDF]
, 2009 For the first time, estimates of heating and cooling in the upper thermosphere due to dissipating and breaking gravity waves ( GWs) of tropospheric origin have been obtained with a comprehensive general circulation model ( GCM).

Tamkang Journal of Mathematics, 1998 We are concerned with the steady wave motions in a 2-fluid system with constant densities. This is a free boundary problem in which the lighter fluid is bounded above by a free surface and is separated from the heavier one down below by an interface. By using a contractive mapping principle type argument.

Modulation of surface gravity waves by internal waves [PDF]
Journal of Physical Oceanography, 2021 AbstractInternal waves are a regular feature of the open ocean and coastal waters. As a train of internal waves propagate, their surface induced currents modulate the surface waves, generating a characteristic rough and smooth banded structure. While the surface expression of these internal waves is well known and has been observed from a variety of ...

On the nonlinear shaping mechanism for gravity wave spectrum in the atmosphere [PDF]
Annales Geophysicae, 2009 The nonlinear mechanism of shaping of a high vertical wave number spectral tail in the field of a few discrete internal gravity waves in the atmosphere is studied in this paper.

Interaction Features of Internal Wave Breathers in a Stratified Ocean
Fluids, 2020 Oscillating wave packets (breathers) are a significant part of the dynamics of internal gravity waves in a stratified ocean. The formation of these waves can be provoked, in particular, by the decay of long internal tidal waves. Breather interactions can
