  • Chinook wind: A warm, westerly wind found in western North America – Canada and the USA, when air from the Pacific blows over the Rocky Mountains and other upland areas.
  • The Foehn is a warm, dry, gusty wind which occurs over the lower slopes on the lee side (the side which is not directly exposed to wind and weather) of a mountain barrier. It is a result of forcing stable air over a mountain barrier. The onset of a Foehn is generally sudden. Foehn winds occur quite often in the Alps (where the name föhn originated) and in the Rockies (where the name chinook is used).UPSC Prelims 2024 dynamic test series
