ON BREAKING OF INTERNAL GRAVITY WAVES

Internal gravity waves are considered as primary oscillations in an environment that is described in the mean by a stable density variation and a shear flow velocity. By considering a small scale secondary wave riding on the primary carrier, it is found that energy concentration is possible on the crests and breakdown is expected. The mechanism is shown to be possible even if the mean Richardson number denotes stability. (Author)
