Shoaling internal solitary waves
[1] The evolution and breaking of internal solitary waves in a shallow upper layer as they approach a constant bottom slope is examined through laboratory experiments. The waves are launched in a two-layer fluid through the standard lock-release method. In most experiments, the wave amplitude is significantly larger than the depth of the shallow upper layer so that they are not well described b...
متن کاملInternal Solitary Waves
The basic theory of internal solitary waves is reviewed, with the main emphasis on applications to the many observations of such waves in shallow coastal seas, fjords, lakes and in the atmospheric boundary layer. Commencing with the equations of motion for an inviscid, incompressible density-stratified fluid, we describe asymptotic reductions to model long-wave equations, including the well-kno...
متن کاملAtmospheric Internal Solitary Waves
The solitary waves that have been observed in the atmosphere fall broadly into two classes: those that propagate in a fairly shallow stratified layer near the ground and those that occupy the entire troposphere. We present a survey of the observations of both types of solitary waves. The generation mechanisms differ substantially for these two types of solitary waves. Those that propagate in a ...
متن کاملA regularized model for strongly nonlinear internal solitary waves
The strongly nonlinear long-wave model for large amplitude internal waves in a two-layer system is regularized to eliminate shear instability due to the wave-induced velocity jump across the interface. The model is written in terms of the horizontal velocities evaluated at the top and bottom boundaries instead of the depth-averaged velocities, and it is shown through local stability analysis th...
متن کاملReview of Internal Solitary Waves
A variety of waves can be generated in the region between two fluids of different densities. These so called internal waves are dispersive and nonlinear even for modest amplitudes. This paper provides an review of various models (from weakly to fully nonlinear) of internal waves in the density-stratified flows. The properties of these waves as well as the processes of generation, interaction an...
