File talk:Low pressure system over Iceland.jpg

When this image is unprotected, the first sentence in the description should be changed to say either "southeastern coast of Greenland" (like in the original description page from NASA), or "southwestern coast of Iceland". 128.205.161.110 07:49, 26 February 2006 (UTC)

Thanks. You can also ask an admin to correct a protected page. I've changed it to "southwestern coast of Iceland", as the centre of the low looks closer to Iceland than Greenland.

Interestingly, the page history shows that the caption read 'southeastern' in the original upload. I would be surprised if Brian did anything other than a cut-n-paste copy from the NASA page - I wonder whether NASA had their caption wrong originally? -- Solipsist 15:03, 26 February 2006 (UTC)

Coriolis force?

"And because this low-pressure system occurred in the Northern Hemisphere, the winds spun in toward the center of the low-pressure system in a counter-clockwise direction; a phenomenon known as the Coriolis force (in the Southern Hemisphere, the Coriolis force would be manifested in a clockwise direction of movement)."

The above statement is not entirely correct. On the image http://commons.wikimedia.org/wiki/Image:Coriolis_effect10.png the Coriolis force is indicated by red arrows, and the pressure gradient force is indicated by blue ones. If you use the quoted sentence, use the term "Coriolis effect" instead, which means a combination of the Coriolis force and other forces.

If you want to get a better explanation, please read "You have it backwards" in this FAQ: http://www.ems.psu.edu/~fraser/Bad/BadFAQ/BadCoriolisFAQ.html.

The nature of this system

It was neither a polar low nor polar vortex— it was typically a storm-force and occluded extratropical cyclone. The surface weather map at 12:00 UTC on 4 September 2003 provided by the Ocean Prediction Center can prove the truth. -- Meow 18:37, 14 October 2014 (UTC)
