The Influence of Topography on Steady Currents and Internal Waves.
Abstract
Observations of the ocean in the vicinity of Bermuda on two different occasions show systematic distortions of the isotherms close to the island and an area of intensive mixing on the northern coast. Two mechanisms are investigated and each produces some agreement with data from different flow regimes. First, the island is modeled as a circularily symmetric obstacle with steep sides and a small aspect ratio. A steady, rotating, stratified flow which, far from the island, is uniform in the horizontal and a linear function of the vertical coordinate is taken to be flowing past the island. A second means of producing isotherm distortion and mixing areas close to the island is the shoaling of internal gravity waves on a beach. (Author)
