Development of internal solitary waves in various thermocline regimes-a multi-modal approach
internal solitary waves various thermocline regimes multi-modal approach
2009/11/12
A numerical analysis is made on the appearance of oceanic internal solitary waves in a multi-modal setting. This is done for observed profiles of stratification from the Sulu Sea and the Bay of Biscay...

Internal Solitary Waves Moving Two-Dimensional Topography
2009/2/23
The propagation of long internal waves over two-dimensional topography is discussed. A two-dimensional version of the Korteweg-deVries equation is derived with variable coefficients which depend on th...

The propagation into the Alboran Sea of the interface depression generated at the Strait of Gibraltar by the interaction of the semidiurnal tidal current with the main (Camarinal) sill is studied nume...
Capture and Resonant Forcing of Solitary Waves by the Interaction of a Baroclinic Current with Topography
Solitary Waves Baroclinic Current Topography
2008/12/17
The authors have demonstrated that a large amplitude, nearly stationary solitary wave can be induced either by direct resonant forcing or by the capture of a traveling wave over the forcing region, us...

The observation of internal solitary waves (ISWs) propagating upstream along a strongly stratified bottom layer on the California shelf is reported. An increased concentration of particulates in the w...
A Nonlinear Model of the Shoaling and Refraction of Interfacial Solitary Waves in the Ocean. Part II: Oblique Refraction across a Continental Slope and Propagation over a Seamount
Nonlinear Model Interfacial Solitary Waves Oblique Refraction Continental Slope Seamount
2008/7/25
The refraction of internal solitary waves can be due to variations in water depth, nonlinearity, stratification, or shear. This paper addresses the effects of the first two of these effects. Part I of...
