Which description best describes a rainshadow effect? A rain shadow is a dry area on the leeward side of a mountainous area. The mountains block the passage of rain - producing weather systems and cast a "shadow" of dryness behind them. Cold, moist air is blown into the mountain where it drops all of its moisture. Cold air comes off the ocean and travels up the mountain dumping rain on the leeward side. An area having relatively vast precipitation due to the effect of a topographic barrier, especially a mountain range, that causes the prevailing winds to lose their moisture on the leeward side.
