In other projects Wikimedia Commons. The Ekman spiral is a structure of currents or winds eespiral a horizontal boundary in which the flow direction rotates as one moves away from the boundary. But he did have lots of time to make observations of the environment.

Moving files to Commons for details. On the influence of the Earth’s rotation on ocean currents. The force from above is in red beginning with the wind blowing over the water surfacethe Coriolis force which is shown at right angles to the force from above when it should in fact be at right angles to the actual water flow is in dark yellow, and the net resultant water movement is in pink, which then becomes the force from above for the layer below it, accounting for the gradual clockwise spiral motion as you move down.

Ocean water at the surface moves ekmwn an angle to the wind, and the water under the surface water turns a bit more, and the water below that turns even more.

Ekman spiral – Wikipedia

Walfrid Ekman who first described the spiral in Archived eapiral the original on Because the Earth rotates, surface water moves to the right of the wind direction in the Northern Hemisphere and to the left of the wind direction in the Southern Hemisphere due to the Coriolis effect.

The example shown above is for the Northern Hemisphere.

Retrieved from ” https: This surface current drags on the water layer below it, applying a force in its own direction of motion to ekma layer, repeating the process whereby that layer ekkman becomes a steady current even further to the right of the wind, and so on for deeper layers of water, resulting in a continuous rotation or spiraling of current direction with changing depth.

The classic Ekman spiral has been observed under sea ice, [3] but observations remain rare in open-ocean conditions.

As wind blows across the ocean, it moves water because of friction at the ocean surface. This makes a spiral of moving water to meters fkman ft deep called an Ekman spiral.

A structure of currents or winds near a horizontal boundary in which the flow direction rotates as fkman moves away from the boundary. Journal of Physical Oceanography.

The first documented observations of an oceanic Ekman spiral were made in the Arctic Ocean from a drifting ice floe in He thought that trapped in eman ice, which moves with ocean currents, he would get to the North Pole eventually.
