WHAT DOES EKMAN SPIRAL MEAN IN ENGLISH?

Ekman spiral

The Ekman spiral refers to a structure of currents or winds near a horizontal boundary in which the flow direction rotates as one moves away from the boundary. It derives its name from the Swedish oceanographer Vagn Walfrid Ekman. The deflection of surface currents was first noticed by the Norwegian oceanographer Fridtjof Nansen during the Fram expedition. The effect is a consequence of the Coriolis effect which subjects moving objects to a force to the right of their direction of motion in the northern hemisphere. Thus, when a persistent wind blows over an extended area of the ocean surface in the northern hemisphere, it causes a surface current which accelerates in that direction, which then experiences a Coriolis force and acceleration to the right of the wind: the current will turn gradually to the right as it gains speed. As the flow is now somewhat right of the wind, the Coriolis force perpendicular to the flow's motion is now partly directed against the wind.

Definition of Ekman Spiral in the English dictionary

The definition of Ekman Spiral in the dictionary is a complex interaction on the surface of the sea between wind, rotation of the earth, and friction forces, discovered by Vagn Walfrid Ekman.
