What effect does orographic lifting have on weather patterns?

• A. Decreases precipitation in the area
• B. Creates turbulence in the atmosphere
• C. Enhances cloud formation and precipitation
• D. Stabilizes the air mass

Answer: (C)

Orographic lifting occurs when moist air is forced to rise as it encounters elevated terrain, such as mountains. As the air ascends, it cools due to the decrease in atmospheric pressure at higher altitudes. This cooling process can reach the dew point, leading to condensation and the formation of clouds. As the process continues, especially if the air is sufficiently moist and the ascent is strong enough, the condensation can result in significant precipitation on the windward side of the mountain range. The enhancement of cloud formation and precipitation associated with orographic lifting plays a crucial role in the local climate, often leading to wetter conditions in areas adjacent to the elevated terrain. The leeward side of the mountains, however, typically experiences a rain shadow effect, where precipitation is reduced, but this does not negate the fact that orographic lifting itself is responsible for enhancing precipitation on the windward side. Thus, the correct answer reflects the direct relationship between orographic lifting and increased precipitation in affected areas.
