Nonlinear internal wave interactions

AIP Conference Proceedings, 1981
We are presently engaged in the direct numerical calculation of the interactions among a set of random internal gravity waves. The calculations are in 2‐D using a pseudo‐spectral code of 128×128 spectral components. They are initialized using the Garrett‐Munk spectrum.

Weakly Nonlinear Internal Waves in Shear

Studies in Applied Mathematics, 1981
An evolution equation in a finite depth fluid for weakly nonlinear long internal waves is derived in a stratified and sheared medium. The equation reduces to the Korteweg‐deVries equation when the depth is small compared to the wavelength, and to the Benjamin‐Ono equation when the depth is large compared to the wavelength.

Observations of Large-Amplitude Mode-2 Nonlinear Internal Waves on the Australian North West Shelf

Journal of Physical Oceanography, 2019
Large-amplitude mode-2 nonlinear internal waves were observed in 250-m-deep water on the Australian North West shelf. Wave amplitudes were derived from temperature measurements using three through-the-water-column moorings spaced 600 m apart in a ...

Nonlinear internal wave study during ASIAEX

Proceedings of the 2004 International Symposium on Underwater Technology (IEEE Cat. No.04EX869), 2005
In recent Asian Seas International Acoustics Experiment (ASIAEX), extensive moorings have been deployed around the continental shelf break area in the northeast of South China Sea in May 2001. Simultaneous RADARSAT SAR images have been collected during the field test to integrate with the in situ measurements from moorings, ship-board sensors, and CTD ...

Nonlinear internal waves in the atmosphere

The Journal of the Acoustical Society of America, 1975
Nonlinear dispersive effects on the propagation of atmospheric internal waves are investigated. The finite amplitude buoyancy oscillation is analyzed to obtain an amplitude−dependent oscillation frequency. A nonlinear dispersion relation for finite−amplitude internal waves is derived. Its relation to the nonlinear buoyancy oscillation is discussed. The

Nonlinear, periodic, internal waves

Fluid Dynamics Research, 1990
It is shown how to calculate large-amplitude, periodic, internal waves in a channel filled with continuously stratified fluid by using a Stokes-type amplitude expansion along the channel and a modal expansion across the channel. We obtain explicit solutions for the case where the density increases exponentially with depth.

Energy Transport by Nonlinear Internal Waves

Journal of Physical Oceanography, 2007
Abstract Winter stratification on Oregon’s continental shelf often produces a near-bottom layer of dense fluid that acts as an internal waveguide upon which nonlinear internal waves propagate. Shipboard profiling and bottom lander observations capture disturbances that exhibit properties of internal solitary waves, bores, and gravity ...

Internal waves

Proceedings of the European Wave and Tidal Energy Conference, 2023
Internal waves are ubiquitous oceanographic features that occur in various forms across the world’s oceans. They manifest themselves as interface waves across ocean density layers that represent the interplay between buoyancy and gravitational forces ...

Amplitude Bounds for Nonlinear Internal Waves

Volume 3: Materials Technology; Ocean Engineering; Polar and Arctic Sciences and Technology; Workshops, 2003
Amplitude bounds imposed by the conservation of mass, momentum and energy for internal gravity waves are considered. We discuss the theoretical schemes intended for a description of permanent waves just up to the broadening limit. Analytical methods which allow to determine the critical amplitude values for the current with a given density profile are ...

Nonlinear interactions among internal gravity waves

Reviews of Geophysics, 1986
This paper reviews the nonlinear interaction calculations for the internal gravity wave field in the deep ocean. The nonlinear interactions are a principal part of the dynamics of internal waves and are an important link in the overall energy cascade from large to small scales.
