Abstract

It is shown that a slight modification to the ray ansatz of short wave asymptotics can lead to a considerable improvement in the uniformity of the solution. A superposition of ray solutions is used to obtain a description of the sound waves generated by a multi-pole point source in a weakly stratified ocean.
