Abstract: The complex eigenvalues of frequency are computed for Hough functions of negative equivalent depth, using the method of Longuet-Higgins. The positive kinetic wave energy and negative wave potential energy of unstable modes ...

Abstract: A simple numerical model is used to demonstrate that momentum exchange between wave and mean flow can substantially modify the process of ?breaking? of internal gravity waves at great height. The momentum exchange results ...

Abstract: A numerical model of internal gravity waves allows momentum transport by the waves to interact with the mean flow. Momentum deposited at a critical level develops a ?shelf? in the mean flow. Mean flow acceleration ...
