Internal Wave Interferometry [PDF]
Physical Review Letters, 2010 Internal waves are a ubiquitous and significant means of momentum and energy transport in the oceans, atmosphere, and astrophysical bodies. Here, we show that internal wave propagation in nonuniform density stratifications, which are prevalent throughout nature, has a direct mathematical analogy with the classical optical problem of a Fabry-Perot ...

Internal Waves and Waves of Sand [PDF]
Nature, 1960 A DESCRIPTION has been given of some large sand waves on La Chapelle Bank which lie parallel to the general direction of the edge of the continental shelf1. They occur within a zone about 10 miles wide, have a mean separation of 2,800 ft. and are up to 40 ft. high.

, 2019 The ocean's interior is filled with waves that can only exist because the ocean is vertically stratified in temperature and salinity. Like waves at the ocean surface, internal waves are restored by gravity. These internal gravity waves are generated by wind, tides, and low-frequency flows.

Orbital Stability of Internal Waves [PDF]
Communications in Mathematical Physics, 2022 This paper studies the nonlinear stability of capillary-gravity waves propagating along the interface dividing two immiscible fluid layers of finite depth. The motion in both regions is governed by the incompressible and irrotational Euler equations, with the density of each fluid being constant but distinct.

On the internal wave variability during the Internal Wave Experiment (IWEX) [PDF]
Journal of Geophysical Research: Oceans, 1981 The relation between internal wave variability and larger and smaller scales of motion is investigated, using the IWEX data set. To investigate the role of internal waves in the vertical diffusion of large scale momentum, the time variability of the vertical flux of horizontal internal wave momentum (estimated from temperature and current data) is ...

Dependence of Internal Wave Bolus Transport on Pycnocline Thickness
Geophysical Research Letters, 2020 A bolus is a vortex formed by an internal wave propagating upslope with the shoaling wave. The amount of sediment and biota transported by boluses travelling up the world's continental slopes and onto the continental shelves has not been established but ...

Russian Journal of Earth Sciences, 2023 The mechanisms of manifestation of internal waves in satellite data of the optical range are considered for the mouth area of the Danube. Three main mechanisms for the manifestation of internal waves are identified – the previously described dynamic (due

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.

Large amplitude internal solitary waves over a shelf [PDF]
Natural Hazards and Earth System Sciences, 2011 Dynamics of large amplitude internal waves in two-layers of shallow water is considered. It is demonstrated that in laboratory experiments the subsurface waves of depression over a shelf may be simulated by internal symmetric solitary waves of the mode 2

Transient development of gravity waves for two layered fluids
International Journal of Mathematics and Mathematical Sciences, 1992 The transient gravity waves generated by a harmonically oscillating wave maker immersed in two incompressible fluids, the upper fluid having a free surface, is considered.
