What is a rain shadow?

Quick Answer
A rain shadow is a dry area on the leeward side of a mountain range. It forms when mountains force moist air upward, causing rain to fall on the windward side.
The Full Story
A rain shadow is a region of reduced rainfall that develops downwind of a mountain range. As moist air rises over the mountains, it cools and loses much of its moisture as precipitation on the windward slope. The air then descends on the leeward side, warming and drying out, which suppresses rainfall. Classic examples include the eastern side of the Sierra Nevada and parts of Patagonia east of the Andes.
Key Facts
1.Rain shadows form because rising air cools and condenses
2.The leeward side of mountains is usually much drier
3.The Andes and Sierra Nevada both create strong rain-shadow effects
