Concept:The rain shadow effect occurs on the leeward side of a mountain, where dry conditions prevail due to blocked moisture.
Explanation:Rainfall caused by mountains forcing moist air to rise is called orographic rainfall.
The windward side receives heavy rain as air cools and condenses.
The leeward side remains dry, creating a rain shadow region.
Example: Vidarbha in Maharashtra lies on the leeward side of the Western Ghats.
Cyclonic rainfall is caused by convergence of different air masses in temperate or tropical areas.
Convectional rainfall occurs when ground heating causes rising air to form cumulonimbus clouds.
Frontal rainfall is another name for cyclonic rainfall, not related to mountains.
Answer:B. Orographic rainfall
