Concept:The term "Inversion of Rainfall" refers to a phenomenon where rainfall is greater on the windward side of a mountain and significantly less on the leeward side.
Explanation:In orographic rainfall, moist air is forced to rise over a mountain barrier.
As the air ascends, it cools and condenses, forming clouds and causing precipitation on the windward slope.
After crossing the summit, the now dry air descends on the leeward side, warming and inhibiting cloud formation.
This leeward region receives very little rain, creating a rain-shadow area.
This sharp contrast in rainfall (heavy on windward, scarce on leeward) is termed "inversion of rainfall."
Among the given options, only orographic rainfall produces such a distinct spatial inversion.
Answer:A. Orographic rainfall
