Foehn winds are also referred to as East winds.

• A. East winds
• B. West winds
• C. North winds
• D. South winds

Answer: (A)

Foehn winds are warm, dry downslope winds that form when moist air rises over a mountain range, loses moisture on the windward side, and then descends the leeward side, warming as it compresses. In this context, the downslope flow toward the eastern side of a range is referred to as East winds. So the label East winds matches the terminology used for this phenomenon in the material, even though the same physical process is known by different regional names in other places (like Föhn or Chinook). The important idea is recognizing that Foehn winds are a downslope, warming wind on the leeward side, and the East winds nomenclature is just the regional term used here.
