Turbulence Closure and 3-D Ocean Modeling for CBLAST

Abstract

As part of the CBLAST-DRI Program, my long-term goal is to improve the numerical modeling of the coastal ocean and its interaction with atmospheric forcing. An objective is to improve the Mellor-Yamada turbulence closure model for ocean surface and bottom boundary layers and, specifically, to include the effects of surface waves. It is observed that there is a mismatch in surface wave modeling and ocean circulation modeling. The wave community models surface waves but neglects vertical variations in the mean current fields in which the waves are physically imbedded. The ocean circulation community explicitly models the vertical structure of the ocean but generally ignores surface waves and their contribution to vertical mixing of ocean properties. There are researches \201e.g., Craig and Banner 1994, Terray et al. 2000\202 that do recognize wave-mixed layer interaction but, generally, the aforementioned mismatch prevails.
