Internal Waves Radiated by a Moving Source. Volume 1. Analytic Simulation

Abstract

An algorithm is derived for the efficient simulation of internal waves radiated from an object moving at constant speed in a medium of arbitrarily stratified density. The algorithm is based on a Fourier/normal-mode expansion of the linearized fluid equations in rectangular coordinates, and owes its efficiency to the Fast Fourier Transform used for numerical inversion of the analytically-derived field transforms. Sample calculations from a prototype computer program, XMODE, are described.
