A rain shadow is a dry area on the lee back side of a mountainous area. The mountains block the passage of rain-producing weather systems casting a "shadow" of dryness behind them.
As shown by the diagram to the right, the incoming warm and moist air is "pulled" by the prevailing winds towards the top of the mountains where it condenses and precipitates before it crosses the top. The air, without much moisture left, advances behind the mountains creating a dryer side called "rain shadow."

Famous quotes containing the words rain and/or shadow:
“... his voice and hands,
Within whose warm spring rain of loving care
Each dwells some twenty seconds. Now, dear child,
What’s wrong, the deep American voice demands,
And, scarcely pausing, goes into a prayer
Directing God about this eye, that knee.”
—Philip Larkin (1922–1986)
“An institution is the lengthened shadow of one man.”
—Ralph Waldo Emerson (1803–1882)
