In North America, the wind that flows down the eastern side of the Rocky Mountains is called the Chinook. It is a local wind that provides a dramatic break from the winter cold.

The Chinook wind is a staple of North American geography. Its name comes from the Chinookan people who lived near the Columbia River. The wind is essentially a “rain shadow” wind. As the air moves from the Pacific toward the interior of Canada and the United States, the Rocky Mountains act as a giant wall. The air that manages to cross the wall is dry and heats up as it drops toward the plains. This creates a narrow corridor of warm weather that stretches along the eastern edge of the mountains, often creating a sharp contrast with the snow-covered land.
