A Geometric Model of Horizontal Sound Refraction through a Circular Eddy.
Sound rays spread horizontally more rapidly upon refraction across a warm eddy than a homogenous water mass. The reverse is true of a cold eddy, causing shadow zones. Focal lengths and position of apparent images are the same using the cylindrical model or the physical thin-lens equation. (Author)
