Dubious
The map at the start of the article, Image:Map prevailing winds on earth.png, shows the trade winds originating as far north as somewhere near South Dakota -- clearly above latitude 40°N, anyway. I do not believe that can possibly be right -- weather systems pretty much move west to east across the whole of the "Lower 48" states of the US, so the prevailing winds in that whole area must be the westerlies. As shown on this map, for example: http://www.colorado.edu/geography/blanken/GEOG%206181%20Fall%202003/noble/images/06_tradewind_1.jpg.
The same incorrect map is in Wikimedia Commons and is linked from several other articles in the English-language Wikipedia alone, but the instructions there say to report problems at the talk page of an article using the image. So I'm posting here and adding a "dubious" tag to the map caption in the article.
Can a better map of prevailing winds, available for use in Wikipedia, be found or created? --70.48.230.201 (talk) 05:38, 14 April 2010 (UTC)
- Wikimedia commons has a similar illustration at File:Earth Global Circulation.jpg which, like the one you mentioned at the University of Colorado, is not an earth surface projection map but it does try to show a side view cross section of the Hadley cells at the limbs of the earth's disk. I suspect the extent of the Hadley cells beyond 30° latitudes North or South is not shown on the illustration I mentioned. It may suit your preference. 69.126.127.193 (talk) 03:16, 31 March 2011 (UTC)
- I agree the South Dakota arrow should not be there, as the trades should not extend beyond the horse latitudes of 30-35 degrees. You could fix the map by downloading it, covering over the bad arrow, and uploading the result, replacing the existing file. -R. S. Shaw (talk) 00:50, 8 August 2011 (UTC)
This issue has been fixed some months back, so I've removed the "Dubious" tag. (I wonder whether the problem didn't originate as a [mis]representation of winds at a time of year when the subtropical ridge is most northerly -- the northern summer -- and the trade winds might, in fact, possibly arise that far north?) -- Perey (talk) 06:00, 23 September 2012 (UTC)

The result of the move request was: moved. A history swap was also required. Jenks24 (talk) 10:52, 13 July 2015 (UTC)
Trade wind → Trade winds – The topic is not an individual wind, but a system of prevailing winds, similar to the westerlies and the Roaring Forties, where we also use plurals. Compare also the plural forms for the doldrums and the horse latitudes. --Lambiam 18:46, 5 July 2015 (UTC)
