Concept:The Harmattan is a dry, dusty trade wind that blows from the Sahara Desert into West Africa during the dry season.
Explanation:Between November and February, West Africa experiences its dry season.
During this period, high pressure over the Sahara Desert pushes dry, dust-laden air southward.
This wind moves from the northeast toward the Gulf of Guinea.
It is locally known as the Harmattan.
The Harmattan brings dry weather, hazy skies, and reduced visibility.
It is distinct from the other options: Chinook is a warm wind in North America, monsoon winds bring seasonal rain, and a land breeze is a local coastal wind.
Answer:A. Harmattan
