Which one of the following is the example of planetary winds?
-
Monsoon
-
Trade wind
-
Land and sea breezes
-
Chinook
B
Correct answer
Explanation
Planetary winds are large-scale atmospheric circulation patterns that blow across the Earth's surface. Trade winds are permanent planetary winds that blow from the subtropical high-pressure belts toward the equatorial low-pressure zone. While monsoons are also planetary (seasonal) winds, trade winds are the classic example cited in textbooks. Land and sea breezes and Chinook are local winds, not planetary.
