Question

What is the effect of Chinook in the central plains in the USA?
1. Temperature of winter rises
2. Temperature of summer reduces
3. Uniform temperature
4.  No effect on temperature

Answer 1

Correct Answer - Option 1 : Temperature of winter rises

The correct answer is Temperature of winter rises.

• In the cold winter months of regions east of the Rocky Mountains, a strong, dry, warm wind sometimes blows from the mountains across the land. These winds, known as Chinook winds, can bring quick temperature changes.
• Chinook winds develop when warm, moist air blows from the Pacific Ocean in the northwest region of North America toward the Rocky Mountain range.
• The air mass cools as it climbs the mountains, bringing rain or snow to the peaks.
• Chinook winds – also known as Foehn winds in other parts of the world – are a type of warm, dry wind that occurs on the downward slope of a mountain when warm air has lost its moisture.
