Correct Answer:
Option D —
Orographic rainfall
Orographic rainfall (also known as Relief rainfall) occurs when moist air is forced to rise over a physical barrier, such as a mountain range. As the air rises, it cools, condenses, and forms clouds, leading to precipitation.
How Orographic Rainfall Works
The Windward Side: This is the side of the mountain facing the wind. The air is forced upward (orographic lift), cools at the adiabatic lapse rate, and releases moisture as rain or snow.
The Leeward Side: As the air crosses the peak and descends the other side, it warms up and loses its moisture-carrying capacity. This creates a Rain Shadow Area, which is typically very dry or desert-like. Understanding the Other Types of Rainfall
A) Frontal Rainfall: Occurs when a warm air mass meets a cold air mass. The warmer, lighter air is forced to rise over the colder, denser air.
B) Convectional Rainfall: Common in tropical regions, this happens when the sun heats the ground intensely, causing the air above it to warm, expand, and rise rapidly, forming towering clouds.
C) Cyclonic Rainfall: Also known as Cyclonic precipitation, this is associated with low-pressure systems where air converges and is forced upward in the center of the cyclone.
