This paper studies the nonlinear stability of capillary-gravity waves propagating along interface dividing two immiscible fluid layers finite depth. The motion in both regions is governed by incompressible and irrotational Euler equations, with density each being constant but distinct. A diverse collection small-amplitude solitary wave solutions for this system have been constructed several aut...

<abstract><p>Internal gravity waves are propagating disturbances in stably stratified fluids, and can transport momentum energy over large spatial extents. From a fundamental viewpoint, internal interesting due to the nature of their dispersion relation, linear dynamics reasonably well-understood. an oceanographic qualitative quantitative understanding significant wave generation oc...

Laboratory experiments show that as uniformly stratified fluid flows over a smoothly-varying step, two wave-like phenomena result: boundary-trapped lee waves, characterized by an undular shear layer downstream of the base of the step, and internal waves, which propagate vertically away from the step. The frequency of both types of waves is an approximately constant fraction of the buoyancy freq...

[1] We present the results of three‐dimensional, nonhydrostatic simulations of internal tides and waves in the South China Sea (SCS) using the SUNTANS model. Model results accurately predict the observed wave arrival times at two mooring locations in the SCS. Internal wave amplitudes are underpredicted which causes underprediction of internal wave speeds due to a lack of amplitude dispersion. W...
