"Chinook" is used for coastal Chinook winds in British Columbia, and is the original use of the term, being rooted in the lore of coastal natives and immigrants, and brought to Alberta by French-speaking fur-traders. [1] [9] Such winds are extremely wet and warm and arrive off the western coast of North America from the southwest.
The winds that result are often gusty and can also create dramatic temperature changes by pushing away cold air at lower elevations. One of the most extreme examples of warming from a chinook ...
In the Great Plains of the United States, these winds are known as a chinook. Downslope winds also occur in the foothills of the Appalachian mountains of the United States, [57] and they can be as strong as other downslope winds [58] and unusual compared to other foehn winds in that the relative humidity typically changes little due to the ...
The causes of the Foehn effect in the lee of mountains (adapted from: [1]) Dissolving Föhn clouds over Cumbre Nueva, La Palma, at an elevation of 1,400 m (4,600 ft) A Foehn, or Föhn (UK: / f ɜː n /, US: / f eɪ n / fayn, [2] [3] US also / f ʌ n, f ɜːr n / fu(r)n [4] [5]), is a type of dry, relatively warm downslope wind in the lee of a mountain range.
Santa Ana winds occur when winds blow and pick up speed as they travel from the inland deserts toward the coast. These wind events usually kick off in the fall and winter months in the Los Angeles ...
The Santa Anas are katabatic winds (Greek for "flowing downhill") arising in higher altitudes and blowing down towards sea level. [7] The National Weather Service defines Santa Ana winds as "a weather condition [in southern California] in which strong, hot, dust-bearing winds descend to the Pacific Coast around Los Angeles from inland desert regions".
Jan. 23—Chinook winds blew through Southcentral Alaska on Friday and Saturday, bringing unseasonably warm weather, slush, ice and rain to Anchorage and surrounding areas. Mild temperatures were ...
Foehn winds usually occur when the westerly wind belt moves northwards. [7]The foehn effect on the coastal plains of southeastern Australia is mostly linked with the passage of a deep low pressure system or westerly cold fronts across the Great Australian Bight and southeastern Australia that cause strong winds to reorient virtually perpendicular to some parts of the Great Dividing Range ...
