Ekman velocity and transport. The wind acts directly and frictionally, through vertical eddy viscosity, on the top 50 to 100 meters of the ocean, in the "Ekman layer". In the northern hemisphere, the frictional surface flow is at an angle to the right of the wind (45 degrees if viscosity is uni Define Ekman layer.

This layer, named for the Swedish oceanographer V. Walfrid Ekman, extends to a depth of about 100 metres (about 300 feet). Ekman Layer Core Dynamics. Ekman layers are boundary layers in which there is a balance between the viscous force and the Coriolis Introduction to Geophysical Fluid Dynamics. Benoit Cushman-Roisin, Jean-Marie Beckers, in International Geophysics, 2011 Surface/Wind Driven Circulation☆. There is 2011-01-01 · Because of the Coriolis effect, the frictional boundary layer of geophysical flows, called the Ekman layer, differs greatly from the boundary layer in nonrotating fluids. Although, the traditional boundary layer has no particular thickness and grows either downstream or with time, the existence of the depth scale d in rotating fluids suggests that the Ekman layer can be characterized by a fixed thickness. Modified Ekman Layer The Ekman layer solution is not applicable to the surface layer.

In a subtropical gyre, the convergent Ekman layer forces water downward into the geostrophic flow below. The properties and depth of the mixed layer vary

Ekman layer

The lowermost layer of the atmosphere or the ocean, adjacent to the land surface in the case of the atmosphere or to the ocean bottom in the case of the ocean, in which the direction of flow turns gradually from the direction of the overlying geostrophic flow, is called the Ekman layer (or the bottom Ekman layer).
