Question

Which of the following types of rainfall occurs when the saturated air mass encounters a mountain and the air is forced to rise?

  1. A. Frontal rainfall
  2. B. Convectional rainfall
  3. C. Cyclonic rainfall
  4. D. Orographic rainfall (Correct answer)

Correct Answer

Option D — Orographic rainfall

Detailed Solution & Explanation

Orographic rainfall (also called relief rainfall) occurs when a moisture-laden air mass is forced to rise over a mountain range or elevated terrain. As the air rises, it cools adiabatically, water vapour condenses, and precipitation falls on the windward (facing the wind) side of the mountain. The leeward side (rain shadow) remains dry. Frontal rainfall occurs at weather fronts; convectional rainfall occurs when heated air rises rapidly; cyclonic rainfall is associated with cyclones.
