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:
“Rain is grace; rain is the sky condescending to the earth; without rain, there would be no life.”
—John Updike (b. 1932)
“The world,—this shadow of the soul, or other me, lies wide around. Its attractions are the keys which unlock my thoughts and make me acquainted with myself. I run eagerly into this resounding tumult. I grasp the hands of those next to me, and take my place in the ring to suffer and to work, taught by an instinct, that so shall the dumb abyss be vocal with speech.”
—Ralph Waldo Emerson (1803–1882)
