← GeographyWhich atmospheric outcome results from the rain shadow effect on the leeward side of a tall mountain range?
A)Increased average wind speed
B)Enhanced precipitation frequency
C)Formation of arid or semi-arid conditions✓
D)Decreased diurnal temperature variation
💡 Explanation
When air rises over a mountain range, adiabatic cooling occurs because air parcel expands, causing condensation on the windward side, leaving dry air descending on the leeward side. Therefore arid conditions result on the leeward side, rather than increased wind, precipitation, or temperature variation, which require different cloud formation or pressure systems.
