Internal solitary waves in a variable medium
In both the ocean and the atmosphere, the interaction of a density stratified flow with topography can generate large-amplitude, horizontally propagating internal solitary waves. Often these waves are observed in regions where the waveguide properties vary in the direction of propagation. In this article we consider nonlinear evolution equations of the Kortewegde Vries type, with variable coeff...
متن کاملShoaling 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 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...
