Transmission and reflection of three-dimensional Boussinesq internal gravity wave packets in nonuniform retrograde shear flow
Alain D. Gervais, Gordon E. Swaters, Bruce Sutherland
Abstract
Simulated fully localized internal gravity wave packets with moderately large initial amplitude exhibit finite transmission across a reflection level, due to the combined effects of the wave-induced shear locally cancelling the retrograde background shear, modulational instability, and the nonlinear generation and evolution of secondary wave packets.
