Conference paper


During the last two decades, internal gravity waves have been recognized as an important feature in atmospheric and oceanic dynamics. In both fluids, internal gravity waves account for much of the variability in observed velocity and density profiles and play a role in a variety of processes. However, wave propagation, and therefore wave effects, in the atmosphere and the oceans, are profoundly affected by local velocity shear. In this paper, we examine various aspects of the interaction of internal gravity waves with shear using a numerical model and a laboratory shear flow apparatus.
