Flow and Mixing Properties in wind-Induced Density Currents

Two-types of wind-induced density currents are analytically examined by using a turbulence model. Discussed here are two-dimensional two-layer stratification systems; they are (1) a completely closed system in which both ends are bounded by fixed walls such as lakes and reservoirs and (2) an open system with no fixed boundaries like oceans. Flow and mixing regimes are related to the dimensionless governing parameters which are scaled in terms of the wind shear friction velocity, the horizontal and vertical dimensions of the water body and the buoyancy anomaly of the thermocline interface.
