scale[edit]

On what scale is the ideal Ekman Spiral formed? Is it ocean-wide (and thus a gyre, essentially)? Or is hurricane-sized, or tornado-sized, or what? I know that all sorts of conditions exist to prevent perfect Ekman Spirals from forming, but when they do occur, what size are they?165.91.64.254 (talk) 06:54, 23 September 2008 (UTC)RKH[reply]

Think there should be a definition or link for "pendulum day" used in article. —DIV (128.250.204.118 01:41, 19 March 2007 (UTC))[reply]

Ekman spiral and Ekman layer refer to somewhat different phenomena and should not be merged. --Drphysics 16:35, 28 June 2007 (UTC)[reply]

example[edit]

how do I add this image from wikitravel?

Visualisation of the Ekman spiral in wind near the ground, by the angle of falling water at different heights.

Ekman Spiral diagram is incorrect[edit]

This diagram is incorrect. The Coriolis force (4) should always be at 90 degrees to the current (3) at each depth. Frictional forces are also required to complete the balance and avoid time-dependent flow. Lastly, the decay with depth should be exponential, not linear.131.236.42.180 (talk) 23:58, 21 October 2013 (UTC)[reply]

External links modified (January 2018)[edit]

Hello fellow Wikipedians,

I have just modified 2 external links on Ekman spiral. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

Coriolis force is perpendicular to what?[edit]

I don't understand how the Coriolis force can be always perpendicular to the current direction. It seems to me that Coriolis is always perpendicular to the north-south axis (constant), not to the (variable) direction of the current. Could someone give more explanations about it? — Preceding unsigned comment added by 87.86.104.115 (talk) 08:11, 21 June 2021 (UTC)[reply]

Mergeto Ekman layer[edit]

I just stuck a mergeto tag on this article; see Talk:Ekman layer for discussion. Both articles contain the same formulas, the same solution, similar diagrams, similar discussion. Both are inadequate, in that they fail to provide any physical intuition, beyond saying "oh its just Coriolis". 67.198.37.16 (talk) 19:26, 20 March 2024 (UTC)[reply]
