Solitary internal waves with oscillatory tails

Journal of Fluid Mechanics, 1992
Solitary internal waves in a density-stratified fluid of shallow depth are considered. According to the classical weakly nonlinear long-wave theory, the propagation of each long-wave mode is governed by the Korteweg–de Vries equation to leading order, and locally confined solitary waves with a ‘sech’ profile are possible.

Large internal solitary waves on a weak shear

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2022
Large amplitude solitary internal waves of permanent form propagating in a stratified shallow fluid between the free surface and a horizontal bottom are described by the amplitude equation obtained by a regular asymptotic procedure, which incorporates a complicated nonlinearity and Korteweg–de Vries (KdV) dispersion.

Weak and Strong Interactions between Internal Solitary Waves

Studies in Applied Mathematics, 1984
The interaction of weakly nonlinear long internal gravity waves is studied. Weak interactions occur when the wave phase speeds are unequal; this case includes that of a head‐on collision. It is shown that each wave satisfies a Korteweg‐de Vries equation, and the main effect of the interaction is described by a phase shift.

Yellow Sea Internal Solitary Wave Variability

2002
Our studies are centered in an area south of the Shandong peninsula where the observations of Zhou, Zhang and Rogers [1] showed an anomalous drop in acoustical intensity at 630 Hz. For this region ocean-acoustic modeling studies are performed in conjunction with available SAR observations of internal solitary waves.

Limiting Forms of Internal Solitary Waves

Journal of Offshore Mechanics and Arctic Engineering, 2002
High sensitivity of nonlinear wave structures in the weakly stratified fluid with respect to small perturbations of density in the upstream flow was pointed out by Benney and Ko, Stud. Appl. Math., 59(3), pp. 187–199. In the present paper the influence of fine scale stratification on one of the limiting forms, namely the plateau-shaped solitary waves ...

Internal Tide Transformation and Oceanic Internal Solitary Waves

2006
The transformation of internal tides, or long internal waves, as they propagate over the variable topography of the continental slope and shelf is discussed. Development of a model to describe this transformation is presented and is based on the Korteweg-de Vries equation.

Generation, propagation, and breaking of internal solitary waves

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2005
Tidal, two-layer flow over topography generates a kink of the interface separating an upstream interfacial elevation from a depression above the topography. Upstream undular bores and solitary waves of large amplitude are generated from the interfacial kink. The waves propagate upstream when the tide turns.

Internal solitary waves in Davis Strait

1983
Current meters and a thermistor chain deployed in proximity of a drillship over the continental shelf off Baffin Island revealed the presence of large amplitude internal waves. This thesis reviews properties of the internal waves, observed to propagate away from the coast and to coincide with the local low water phase of the tide, at the drillship. The
