Simple Prediction of Convergence Zone Propagation in Waters Around Australia.

Abstract

The horizontal ranges to convergence zones are determined for waters around Australia, using historical sound speed profile data and a computer model. A good correlation is found between sound speed at the surface and the convergence zone range, but with a different relationship between these parameters than observed in various Northern Hemisphere waters. The relationship between critical depth and surface sound speed for Australian waters is found to be similar to, although not identical with, that for the North Pacific Ocean. (Author)
