Definition of ekman spiral

WebThis so-called Ekman spiral may be the exception rather than the rule, as the specific conditions are not often met, though deflection of a wind-driven surface current at somewhat smaller than 45° is observed when the wind field blows with a steady force and direction for the better part of a day. The average water particle within the Ekman ... WebEkman transport is the net motion of fluid as the result of a balance between Coriolis and turbulent drag forces. In the picture above, the wind blowing North in the northern hemisphere creates a surface stress and a resulting Ekman spiral is found below it in the water column. Ekman transport is part of Ekman motion theory, first investigated ...

WebThe Ekman spiral is perhaps the most iconic feature of the Ekman layer, as it reflects the complex interaction between the wind, the Coriolis force, and the frictional drag. The spiral is characterized by a rotation of the velocity vector to the right (or left) of the wind’s direction, with a progressively decreasing magnitude. WebWhat is the cause of the Ekman spiral?

The Ekman spiral refers to the spiral pattern of water movement that results from the interaction between wind stress and the Coriolis effect. As wind blows across the ocean surface, it … WebThe Ekman spiral occurs as a consequence of the Coriolis effect. When surface water molecules are moved by the wind, they drag deeper layers of water molecules below them. Like surface water, the deeper water is deflected by the Coriolis effect—to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

WebEkman Spiral definition: A structure of currents or winds near a horizontal boundary in which the flow direction rotates as one moves away from the boundary. 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…
