Nonlinear Internal Waves in a Fjord
1978Abstract A pilot study in Knight Inlet, British Columbia has yielded measurements of large amplitude, nonlinear internal waves in the strongly stratified surface layer. A train of several waves with amplitudes exceeding 10 meters and periods of a few minutes, passed the vessel on each flood tide.

Sharp Nonlinear Stability Criterion of Viscous Non-resistive MHD Internal Waves in 3D
Archive for Rational Mechanics and Analysis, 2016We consider the dynamics of two layers of incompressible electrically conducting fluid interacting with a magnetic field, which are confined within a 3D horizontally infinite slab and separated by a free internal interface. We assume that the upper fluid

Evolution equations for strongly nonlinear internal waves
Physics of Fluids, 2003This paper is concerned with shallow-water equations for strongly nonlinear internal waves in a two-layer fluid, and comparison of their solitary solutions with the results of fully nonlinear computations and with experimental data. This comparison is necessary due to a contradictory nature of these equations which combine strong nonlinearity and weak ...

Nonlinear internal waves in a large lake
Doklady Earth Sciences, 2011Comprehensive experiments on the large stratified Lake Onega have been implemented for the first time. Generation and destruction of nonlinear internal waves under different meteorological conditions have been studied.

Seafloor Pressure Measurements of Nonlinear Internal Waves
Journal of Physical Oceanography, 2008Abstract Highly resolved pressure measurements on the seafloor over New Jersey’s continental shelf reveal the pressure signature of nonlinear internal waves of depression as negative pressure perturbations. The sign of the perturbation is determined by the dominance of the internal hydrostatic pressure (p0Wh) due to isopycnal ...

Internally generated nonlinear waves in filament bundles
Mathematics and Computers in Simulation, 2007We develop a geometrical approach for the relative sliding (shear) between filaments in a bundle subjected to bending and twisting deformations, with applications to motility in flagellated cells. Particular examples for helical and toroidal shapes, and combinations of these, are discussed. The resulting equations for sliding, expressed in terms of the

Nonlinear total internal reflection of electromagnetic waves
Radiophysics and Quantum Electronics, 1997We study the stationary solution of an unstable system of interacting inhomogeneous electromagnetic waves and an acoustic wave. It is shown that the instability of this system is of hard type and the threshold of its vanishing is smaller than the excitation threshold.

Nonlinear Internal Solitary Wave on a Pycnocline
Journal of Offshore Mechanics and Arctic Engineering, 2002This paper describes the theory of nonlinear internal-solitary waves of the type observed in coastal seas. It also describes a numerical solution of an initial-value problem that leads to an internal solitary-like wave. The equations solved numerically are the Navier-Stokes, diffusion, and continuity equations.

Energy Budget of Nonlinear Internal Waves Near Dongsha
2008Abstract : Our long-term scientific goal is to understand the mechanisms by which mixing occurs in the ocean and thereby help develop improved parameterizations of mixing for ocean models. Mixing within the stratified ocean is our particular focus as the complex interplay of internal waves from a variety of sources and turbulence makes this a current ...

Nonlinear internal wave packets in shelf zone
Вычислительные технологии, 2019В рамках модели невязкой слабостратифицированной жидкости рассматривается длинноволновое приближение, описывающее нелинейные волновые пакеты типа кноидальных волн. Построены семейства асимптотических решений, одновременно описывающие периодические последовательности приповерхностных волн в форме впадин и придонных волн типа возвышений.
