2328 JOURNAL OF PHYSICAL OCEANOGRAPHY VOLUME 41 On the Patterns of Wind-Power Input to the Ocean Circulation
Pathways of wind-power input into the ocean general circulation are analyzed using Ekman theory. Direct rates of wind work can be calculated through the wind stress acting on the surface geostrophic flow. However, because that energy is transported laterally in the Ekman layer, the injection into th...
