Nonlinear internal gravity wave beams
Journal of Fluid Mechanics, 2003Based on linear inviscid theory, a two-dimensional source oscillating with frequency $\omega_{0}$ in a uniformly stratified (constant Brunt–Väisälä frequency $N_{0}$) Boussinesq fluid induces a steady-state wave pattern, also known as St Andrew's Cross, that features four straight wave beams stretching radially outwards from the source at angles $\pm ...

Moments of internal gravity waves
The Journal of the Acoustical Society of America, 2001Observations have revealed the widespread distribution of internal waves in deep oceans, shallow seas, lakes and reservoirs. Much theoretical, numerical, laboratory and field work has studied their generation and propagation, and in particular significant progress has been made in internal solitary wave research.

Rotationally symmetric internal gravity waves
International Journal of Non-Linear Mechanics, 2012Many mathematical models formulated in terms of non-linear differential equations can successfully be treated and solved by Lie group methods. Lie group analysis is especially valuable in investigating non-linear differential equations, for its algorithms act here as reliably as for linear cases.

Experimental internal gravity wave turbulence
2020<p>Stratified fluids may develop simultaneously turbulence and internal wave turbulence, the latter describing a set of a large number of dispersive and weakly nonlinear interacting waves. The description and understanding of this regime for internal gravity waves (IGW) is really an open subject, in particular due to their very ...

Theory of internal gravity wave saturation
pure and applied geophysics, 1989Gravity wave saturation is an important process affecting the transport and deposition of momentum, heat, and constituents in the earth’s atmosphere. This paper informally discusses several saturation mechanisms and their effects, including convection, Kelvin-Helmholtz instability, vortical mode instability, parametric subharmonic instability, and mean

2003
In both the atmosphere and the ocean, the fluid is density stratified, i.e., ρ = ρ(z) (it is also a function of horizontal coordinates and time) so that usually dense fluid underlies lighter fluid. This stratification supports a new class of waves called internal waves.
