Generation of internal waves by moving non-stationary disturbances in a real stratified ocean

Abstract

The plane problem on the generation of linear internal waves by a moving area of time-harmonic surface pressures in a continuously-stratified ocean of constant depth is considered. An analytical relation has been derived for forced internal waves off the site of their generation in the form of an internal wave field superposition corresponding to individual vertical modes. The possible wave regimes are determined. For the Brunt-Vaisala frequency distribution in the North Atlantic, the generation conditions and amplitudes of diverse radiated waves are numerically determined.
