thread_title: Merge to [[rainshadow]]

message: I have always believed a 'rain shadow' was an area of INCREASED rainfall, caused by mountain ranges etc, forcing air to rise, cool and precipitate, creating an area where rainfall is common. 
I see, of course, and accept, that the current usage is quite the reverse. 
However, can anyone advise how or why I could have learned this other definition at a UK school (1960's) and if it has been changed at any time. Macthefork 09:46, 14 August 2007 (UTC)

message: Here's a precipitation map of Virginia 
precipitation:ftp://ftp.ftw.nrcs.usda.gov/pub/prism/maps/va.pdf
clearly showing rainfall patterns within the State of Virginia. Several valleys (not only the Shenandoah) within the western part of the State have rainfall much less than areas to the east of the Blue Ridge Mountains, some parts of which are extremely rainy (likely snowy in winter). The driest spot in Virginia that I noticed was in Harrisonburg and surrounding Rockingham County. That's far from being desert, and not quite steppe. 
But it can explain why the Shenandoah Valley is more suited to fruit and grain production than wetter parts of the State. rainshadow
....
The high relief of the Appalachian and Blue Ridge Mountain systems also helps to control  Virginia’s climate. ... Along the Appalachian and Blue Ridge Mountains of western Virginia, this airflow is sometimes from the west and sometimes from the east. When the flow is from the west, the New River and Shenandoah River valleys are in the rain shadow of the Appalachian Mountains; when the airflow is from the east, they are in the shadow of the Blue Ridge Mountains. As a result, both the New River and the Shenandoah River valleys are the
driest portions of the state. Regions of equally low rainfall are rare in the eastern United States (although common along the eastern margins of the great plains of the central United States.

message: I find that highly unlikly.
When the water condensate the energy used to keep it in gas form is released into the air, when that air get down to the rainshadow areas it is heated by the increased air densetity meaning that if the place in the rains shadow is at the same altitude as the area infront of the mountain the air will be warmer then on the other side because of the added heat from the water leaving gas form.
This only apply when it's allot of wind thou...
The norwegian name of this fenomen, not the rain shadow but the special warm wind this areas often have, is "føn vind".
Unnless I heare any good argumens for why these areas are cooler then other areas I'll change it later one, when I find some profe of these areas being warmer somewhere else then my physics books.
Ps. I would prefere if somone that's better in english then me would do it thou..

thread_title:  Rain shadows being cool areas?

message: I'm not sure if it's just unclear writing, but the article states that deserts east of the Cascades in northern Oregon and most of Washington are part of the Basin and Range Province. This is not supported by the references, and these areas are considered part of the Columbia Plateau as per the USGS. I'll go ahead and fix this unless someone in the field thinks otherwise.

message: Manchester does not have double the rainfall of sheffield, in fact according to the individual Wikipedia articles on the cities, sheffield has a higher rainfall. Likewise I'd love to know how Edinburgh, less than an hours drive from Glasgow with no mountains in between has double the rainfall. The answer is it doesn't.
