Views Read Edit View history. On the influence of the Earth’s rotation on ocean currents. The water turns to the left instead of right in the Southern Hemisphere. If the esliral lacks a description you can check edits the uploader made just after uploading this file with this tool.

This is due both to the fact that the turbulent mixing in the surface layer of the ocean has a strong diurnal cycle and to the fact that surface waves can destabilize the Ekman spiral.

Ocean water at the surface moves at an angle to the wind, and the water under the surface water turns a bit more, and the water below that turns even more. 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: He did this on purpose.

Ekman spiral

Summary [ edit ] http: By using this site, you agree to the Terms of Use and Privacy Policy. The depth to which the Ekman spiral penetrates is determined by how far turbulent mixing can penetrate over the course of a pendulum day. As a work of the U.

File mover What files should be renamed? To help him make a mathematical model of these movements, Ekman used the observations that Fridtjof Nansen made while frozen into the Arctic sea ice. The first documented observations of an oceanic Ekman spiral were made in the Arctic Ocean espital a drifting ice floe in This media file is either in the public domain or published under a free licensedw contains no inbound file links.
