Modeling of baroclinic tides in the shelf zone of Guinea

The equations for motion used in the calculations include the nonlinear terms and those responsible for turbulent viscosity. It is shown that the interaction of the barotropic tide with the continental slope in a stratified fluid generates solitary internal waves, with the wavelength order about 2 km, moving shoreward from the shelf break. Packets of relatively short (200-500 m) waves occur on a solitary wave over the slowly varying depth. Two mechanisms transforming solitary waves into wave packets are considered for different hydrological situations at the polygon. -from Journal summary
