A Study of Vertical Mixing Processes in the Northern Arabian Sea

Abstract

This project is a study of vertical mixing processes in surface boundary layers and subsurface barrier layers of the Northern Arabian Sea (NAS) using Large Eddy Simulation (LES) techniques and turbulence-parameterizing Second Moment Closure (SMC) models, both as column models and implemented in a regional circulation models. The major goals of this study are to contribute to our long-term efforts to understand: 1) The dynamics of barrier layers and surface mixed layers in the N. Arabian Sea; 2) The penetration of radiative and atmospheric fluxes into the ocean interior; 3) Interaction of finescale and submesoscale processes in barrier layer formation; and 4) Characteristics and impact of internal gravity waves trapped above barrier layers. COAWST coupled modeling framework from the SWAN surface wave model.
