Diagnosing Ocean‐Wave‐Turbulence Interactions From Space

Geophysical Research Letters, 2019
Numerical studies indicate that interactions between ocean internal gravity waves (especially those

Energy Spectra of Nonlocal Internal Gravity Wave Turbulence

Physical Review Letters, 2023
Starting from the classical formulation of the weak turbulence theory in a density stratified fluid, we derive a simplified version of the kinetic equation of internal gravity wave turbulence. This equation allows us to uncover scaling laws for the spatial and temporal energy spectra of internal wave turbulence which are consistent with typical scaling

On the Frequency of Internal Gravity Waves in the Atmosphere: Comparing Theory with Observations

Atmosphere
This 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 ...

Internal-wave-induced dissipation rates in the Weddell Sea Bottom Water gravity current [PDF]

Ocean Science
This study investigates the role of wave-induced turbulence in the dynamics of the Weddell Sea Bottom Water gravity current. The current transports dense water from its formation sites on the shelf to the deep sea and is a crucial component of the ...

Internal gravity wave excitation by turbulent convection [PDF]

Monthly Notices of the Royal Astronomical Society, 2013
We calculate the flux of internal gravity waves (IGWs) generated by turbulent convection in stars. We solve for the IGW eigenfunctions analytically near the radiative-convective interface in a local, Boussinesq, and cartesian domain. We consider both discontinuous and smooth transitions between the radiative and convective regions and derive Green's ...

Gravity Waves Due to a Point Disturbance in a Plane Free Surface Flow of Stratified Fluids [PDF]

, 1964
The fundamental solution of the gravity waves due to a two-dimensional point singularity submerged in a steady free surface flow of a stratified fluid is investigated. A linearized theory is formulated by using Love's equations.

Mathematical modelling for gravity waves interactions coupled with localized water vapor and ozone in the atmosphere

Frontiers in Earth Science
In the atmosphere, the interrelationship between dynamics and chemistry results in mutual influence and interaction. The behavior of internal gravity waves is influenced by the thermal effects caused by chemical components present in the atmosphere.

Wave-Driven Mass Loss in the Last Year of Stellar Evolution: Setting the Stage for the Most Luminous Core-Collapse Supernovae

, 2012
During the late stages of stellar evolution in massive stars (C fusion and later), the fusion luminosity in the core of the star exceeds the star's Eddington luminosity.

Internal gravity waves versus inertial waves in the laboratory

Comptes Rendus. Physique
Density-stratified and/or rotating fluids are very common in geophysical and astrophysical flows and enable the propagation of respectively internal gravity waves and inertial waves.

A contribution to the occurrence of undular bores and solitary waves in the lower atmosphere, especially over North Germany

Meteorologische Zeitschrift, 2007
In a stably stratified atmosphere the propagation of small amplitude internal gravity waves is rather common but often not noticed. The appearance of a group of large amplitude, nonlinear gravity waves in the lower atmosphere is, in comparison, a special
