← GeographyWhich atmospheric effect causes increased rainfall on the windward side of mountain ranges aligned perpendicular to prevailing winds?
A)Adiabatic cooling and orographic lift✓
B)Increased solar insolation from elevation
C)Descending air compression and warming
D)Enhanced radiative cooling at high albedo
💡 Explanation
When moist air encounters a mountain range, orographic lift forces it to rise, causing adiabatic cooling and condensation because the air expands and its temperature drops, leading to precipitation. Therefore enhanced rainfall occurs, rather than other effects, as solar insolation, descending air compression, or enhanced radiative cooling mechanisms don't directly increase windward precipitation.
