Toward a K-Profile Parameterization of Langmuir Turbulence in Shallow Coastal Shelves

摘要: AbstractInteraction between the wind-driven shear current and Stokes drift velocity induced by surface gravity waves gives rise to Langmuir turbulence in upper ocean. consists of circulation (LC) characterized a wide range scales. In unstratified shallow water, largest scales engulf entire water column thus are referred as full-depth LC. Large-eddy simulations (LESs) with LC have revealed that vertical mixing due erodes bottom log-law profile, inducing profile resembling wake law. Furthermore, interior column, two sources Reynolds stress, turbulent (nonlocal) transport local production, can combine lead negative mean shear. Meanwhile, near surface, serves intensify small-scale eddies leading enhanced disruption surface...
