What statement describes winds from inland Africa to Britain?

• A. Warm and dry
• B. Cold and dry
• C. Warm and humid
• D. Cold and humid

Answer: (A)

Winds arriving from inland Africa bring air from the Sahara, a very hot, dry desert region. Air masses formed over deserts are typically warm and dry because of the intense heating and the low moisture content in the air above deserts. As this hot, dry air moves toward Britain, it remains warm and dry (even if it cools a bit along the way), so the winds are described as warm and dry. They are not cold or humid, since the source region supplies little moisture and is characterized by high temperatures.
