The Physical Characteristics of Ocean Mixed Layer Using LES Based on PALM Model

Document Type : Original Article

Abstract
The ocean mixed layer (OML)  is a quite turbulent area of the upper layer of the ocean, that is bound from above by air-sea interaction and limited from below by warm water masses that are dynamically stable. Surface buoyancy and wind are sources turbulence in the mixed layer. Since the ocean mixed layer plays an important role in the military industries, oil industry and in the long-term climate change, then recognition characteristics of OML is necessary. In this study, using the Navier-Stokes equations and adapting the PALM(Parallelized Large Eddy Simulation) model equations, also using Large Eddy Simulation method ,LES, and clustering (parallelism) to calculate changes has been mixed layer. PALM is a model that for the study of turbulent fluids with high Reynolds numbers like atmosphere and ocean, taking into account the appropriate and accurate  boundary conditions. Using this model for the Persian Gulf Latitude, temperature difference between ocean and atmosphere and wind stress produce free and forced convections respectively. Model outputs show variability in the  pattern of circulation and mixing during the  different seasons.  These variabilities  can  play an important role in the  oil pollutions,  climate change and other change in the global ocean.
