Waves associated to large scale oceanic motions are gravity waves (Poincaré waves which disperse fast) and quasigeostrophic waves (Rossby waves). In this Note, we show by semiclassical arguments, that Rossby waves can be trapped and we characterize the corresponding initial conditions.
Les ondes associées aux mouvements océaniques à grande échelle sont les ondes de gravité (dites de Poincaré) qui dispersent très vite, et les ondes quasigéostrophiques (dites de Rossby). Dans cette Note, nous montrons par une analyse semiclassique que les ondes de Rossby peuvent être piégées et nous caractérisons les conditions initiales correspondantes.
