Abstract: The validity of shallow-water, weakly nonlinear theory for describing the evolution of a single large internal wave depression into an undular bore is explored by comparing theoretical results with results obtained from a ...

Abstract: Observations of internal solitary-like waves (ISWs) on the Oregon Shelf suggest the presence of Kelvin?Helmholtz billows in the pycnocline and larger-scale overturns at the back of the wave above the pycnocline. Numerical ...

Abstract: The energetics of internal solitary waves (ISWs) in continuous, quasi-two-layer stratifications are explored using fully nonlinear, nonhydrostatic numerical simulations. The kinetic energy of an internal solitary wave is ...

Abstract: We investigate the consequence, at small Ekman number, of adding vertical mixing of momentum terms to the incompressible thermocline equations. We find that choosing the vertical eddy viscosity, ? = Af2/N2, where f is the ...

Abstract: The effect of the inclusion of the horizontal gradients of background density and baroclinic flow on the propagation of linear internal gravity wave packets across the flow is investigated using ray-tracing techniques. The ...
