https://padlet.com/duncannmcmillann/TheChinnokWinds A strong wind that becomes warm and very dry while rapidly descending the lee side of mountain slopes. The wind turbulence is similar to the action river water makes when it hits a rock. As the air flows down, waves are created. The high crest of the wave creates a distinctive cloud band parallel to the mountains called a chinook arch en-us 2019-04-05 23:56:14 UTC 2023-05-29 19:25:19 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Clouds.png duncannmcmillann https://padlet.com/duncannmcmillann/TheChinnokWinds/wish/349103668 The mountain ranges of British Columbia, culminating in the Continental Divide between B.C. and Alberta, force wet Pacific air masses to rise and, in doing so, release moisture. By the time the air mass crosses the Continental Divide it has lost its moisture content and descends the eastern slopes of Alberta's Rockies and onto the foothills and prairies as a warm, dry wind, known locally as a "Chinook".]]> 2019-04-06 00:26:05 UTC https://padlet.com/duncannmcmillann/TheChinnokWinds/wish/349103668 duncannmcmillann https://padlet.com/duncannmcmillann/TheChinnokWinds/wish/349103814 2019-04-06 00:28:30 UTC https://padlet.com/duncannmcmillann/TheChinnokWinds/wish/349103814 duncannmcmillann https://padlet.com/duncannmcmillann/TheChinnokWinds/wish/349103929 They're particularly strong in Southern Alberta and northern Montana.

Once its over the Coast and Rocky Mountains, the dry air drops rapidly to the foothills, warming via compression. ]]> 2019-04-06 00:35:42 UTC https://padlet.com/duncannmcmillann/TheChinnokWinds/wish/349104264 duncannmcmillann https://padlet.com/duncannmcmillann/TheChinnokWinds/wish/349105594 For every 100-metre drop in elevation, temperature raises 1*C.
