Propagation of barotropic dipoles over topography in a rotating tank

摘要: Abstract It is shown how symmetric dipolar vortices can be formed by the action of an impulsive jet in a homogeneous single layer fluid rotating tank. These dipoles are allowed to interact with constant topographic slope, which model β-plane or continental shelf. A dipole's trajectory bends toward right when climbing slope and left descending, as predicted numerical simulations analytical arguments. The maximum penetration over adjustment formation trailing lobes compared both two-point vortex model. results suggest that Rossby wave radiation plays important role interaction process.
