| Resonant excitation of coastal Kelvin waves by free inertia–gravity waves
impinging on the coast is studied in the framework of the simplest baroclinic
model: two-layer rotating shallow water with an idealized straight coast. It
is shown that, with respect to the previous results obtained with the
one-layer model, new resonances leading to a possible excitation of Kelvin
waves appear. The most interesting ones, described in the paper, are
resonances of a baroclinic inertia–gravity wave with either another wave of
this kind, or with a coastal current, leading to generation of a barotropic
Kelvin wave. A forced Hopf equation results in any case for the evolution of
the Kelvin wave amplitude. |
