← GeographyWhich mechanism causes increased orographic enhancement of precipitation on prevailing windward slopes?
A)Atmospheric radiative cooling
B)Latent heat driven convection
C)Rapid adiabatic air cooling effect✓
D)Upper-level wind shear enhancement
💡 Explanation
When air is forced to rise over topography, orographic lift occurs because the upward movement causes adiabatic cooling and air saturation as cooled, which condenses moisture and forms clouds, releasing precipitation. Therefore rapid adiabatic air cooling effect occurs rather than radiative cooling, convection, or wind shear changes that are independent factors in cloud formation.
