NONLINEARLY COUPLED INERTIAL AND ROSSBY WAVES

The nonlinear coupling between inertial and Rossby waves is considered accounting for the action of the low-frequency nonlinear force associ ated with the inertial waves. It is found that this interaction is gov erned by a pair of equations, which can be useful for studying the mod ulational instability of a constant amplitude inertial wave as well as the dynamics of nonlinearly coupled inertial and Rossby waves.
