Ray Methods for Internal Waves in the Atmosphere and Ocean

Abstract

We review the use of ray models for internal waves, particularly formulations for calculating wave amplitudes along the ray. These are expressed in spatial, wave number, and phase-space coordinates. The choice of formulation affects not only the difficulty of the calculations for rays and caustics but also the degree to which the waves satisfy slowly varying assumptions. We describe several examples taken from atmospheric and oceanic applications that illustrate the variety of options for ray models.
