Internal waves in marginally stable abyssal stratified flows

Makarenko, Nikolay; Maltseva, Janna; Morozov, Eugene; Tarakanov, Roman; Ivanova, Kseniya

The problem on internal waves in a weakly stratified two-layer fluid is studied semi-analytically. We discuss the 2.5-layer fluid flows with exponential stratification of both layers. The long-wave model describing travelling waves is constructed by means of a scaling procedure with a small Boussinesq parameter. It is demonstrated that solitary-wave regimes can be affected by the Kelvin–Helmholtz instability arising due to interfacial velocity shear in upstream flow.
