Did you know?
The oceanic, wind driven Ekman spiral is the result of a force balance created by a shear stress force, Coriolis force and the water drag. This force balance gives a resulting current of the water different from the winds. In the ocean, there are two places where the Ekman spiral can be observed. At the surface of the ocean, the shear stress force corresponds with the wind stress force. At the bottom of the ocean, the shear stress force is created by friction with the ocean floor… WebEkman Spiral noun a complex interaction on the surface of the sea between wind, rotation of the earth, and friction forces, discovered by Vagn Walfrid Ekman (1874–1954) QUIZ …

Ekman transport is the net movement of water in the ocean due to the Coriolis effect. It is caused by the deflection of water at the surface of the ... WebThe Ekman spiral, named after Swedish scientist Vagn Walfrid Ekman (1874-1954) who first theorized it in 1902, is a consequence of the Coriolis effect. When surface water molecules move by the force of the wind, they, in turn, drag deeper layers of water … Thermohaline circulation begins in the Earth's polar regions. When ocean …
