Webthe global Parallel Ocean Program Model (POP) to examine topographically trapped baroclinic waves around the Seychelles Plateau (S ! 400) in the tropical Indian Ocean. These trapped waves are associated with velocity and temperature oscillations at periods of 15–16 days, similar to the dominant period of some equatorial Yanai waves. Weberal classification of sub-inertial frequency, topographically trapped waves can be broken down into several subclassifications under certain limiting conditions (Wang and Mooers, 1976). In the simple case of an ocean of constant depth with a vertical wall at the coast, these waves are coastal Kelvin waves. In a homog-
