What are the Chinook winds, and what is the impact of this unique Rocky Mountains wind system on local towns and cities?
What will be an ideal response?
Chinook winds are winds associated with very dry, warm air that descends from the mountains to the eastern foothills and plains, especially in winter. When shallow layers of cold air sit over the plains, strong westerly winds warmed by speedy descents from higher altitudes blanket the eastern portions of the mountains, bringing with them dramatic rises in temperature. Towns and cities located on front ranges commonly experience 20 to 30ºF (11 to 17ºC) increases in temperature with significant drops in humidity in short time periods. Students could mention Calgary, Alberta, that once experienced a 30ºF (17ºC) increase in four hours in the month of January.
