Which climatic effect results because mountain ranges force air masses upwards in many global climate regions?

💡 Explanation

When air rises over mountains via orographic lift, adiabatic cooling causes condensation and precipitation, leading to a rain shadow on the leeward side because moisture is depleted on the windward side. Therefore rain shadow formation results, rather than El Niño cycles, erosion or jet stream weakening which have different causal mechanisms.
