ABSTRACT

The spontaneous generation of inertia-gravity waves by balanced motion is investigated in the limit of small Rossby number [epsilon] [much less than] 1. Particular (sheared disturbance) solutions of the three-dimensional Boussinesq equations are considered. For these solutions, there is a strict separation between balanced motion and inertia-gravity waves for large times. This makes it possible to estimate the amplitude of the inertia-gravity waves that are generated spontaneo...
