Chinook is a type of foehn wind, which is a warm, dry, downslope wind that occurs on the leeward side (sheltered side) of a mountain range. The Chinook is specifically associated with the eastern slopes of the Rocky Mountains in North America. As moist air rises over the western slopes, it cools, condenses, and releases precipitation. On the eastern slopes, the air descends, warms adiabatically (due to compression), and becomes drier. This warm, dry wind can cause rapid temperature increases.

– Chinook is a warm, dry wind.
– It occurs on the leeward side of mountain ranges, specifically the eastern slopes of the Rockies.
– It is a type of foehn wind.

Foehn winds occur in many parts of the world, such as the Alps (where they are called Foehn), the Andes (Zonda), and others. The Chinook in North America is famous for causing dramatic temperature rises and rapid snowmelt, earning it the nickname “snow eater.”
