The Generation of Nonlinear Internal Waves [PDF]
Oceanography, 2012 Nonlinear internal waves are found in many parts of the world ocean. Their widespread distribution is a result of their origin in the barotropic tide and in the variety of ways they can be generated, including by lee waves, tidal beams, resonance, plumes,

High-Frequency Nonlinear Internal Waves Around The Philippines [PDF]
Oceanography, 2011 A study of satellite imagery over the Philippines undertaken as part of the US Office of Naval Research Philippine Straits Experiment (PhilEx) found significant high-frequency nonlinear internal wave activity in the waters around the Philippine ...

Nonlinear Fate of Internal Wave Attractors [PDF]
Physical Review Letters, 2013 We present a laboratory study on the instability of internal wave attractors in a trapezoidal fluid domain filled with uniformly stratified fluid. Energy is injected into the system via standing-wave-type motion of a vertical wall. Attractors are found to be destroyed by parametric subharmonic instability (PSI) via a triadic resonance which is shown to

Brief communication: Modulation instability of internal waves in a smoothly stratified shallow fluid with a constant buoyancy frequency [PDF]
Natural Hazards and Earth System Sciences, 2019 Unexpectedly large displacements in the interior of the oceans are studied through the dynamics of packets of internal waves, where the evolution of these displacements is governed by the nonlinear Schrödinger equation.

Examining Breaking Internal Waves on a Shelf Slope Using Numerical Simulations [PDF]
Oceanography, 2012 The subject of internal waves interacting with bottom topographic features in the ocean has received much attention in the past few decades. This heightened interest is mainly due to a conjecture that breaking internal waves at boundaries can be a ...

Strongly nonlinear, simple internal waves in continuously-stratified, shallow fluids [PDF]
Nonlinear Processes in Geophysics, 2011 Strongly nonlinear internal waves in a layer with arbitrary stratification are considered in the hydrostatic approximation. It is shown that "simple waves" having a variable vertical structure can emerge from a wide class of initial conditions.

Internal Waves on the Washington Continental Shelf [PDF]
Oceanography, 2012 The low-frequency oceanography of the Washington continental shelf has been studied in great detail over the last several decades owing in part to its high productivity but relatively weak upwelling winds compared to other systems.

Numerical study of edge waves using extended Boussinesq equations
Water Science and Engineering, 2017 An edge wave numerical model was developed based on extended Boussinesq equations with the internal wave-generation method. The form of edge waves near a seawall was chosen as the input signal in order to avoid treatment of the moving shoreline on a ...

Nonlinear aspects of focusing internal waves [PDF]
Journal of Fluid Mechanics, 2019 When a torus oscillates horizontally in a linearly stratified fluid, the wave rays form a double cone, one upward and one downward, with two focal points where the wave amplitude has a maximum due to wave focusing. Following a former study on linear aspects of wave focusing (Ermanyuk et al., J. Fluid Mech., vol. 813, 2017, pp.

Internal solitary waves: propagation, deformation and disintegration [PDF]
Nonlinear Processes in Geophysics, 2010 In coastal seas and straits, the interaction of barotropic tidal currents with the continental shelf, seamounts or sills is often observed to generate large-amplitude, horizontally propagating internal solitary waves.
