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:
“Love is the hardest thing in the world to write about. So simple. You’ve got to catch it through details, like the early morning sunlight hitting the gray tin of the rain spout in front of her house. The ringing of a telephone that sounds like Beethoven’s “Pastoral.” A letter scribbled on her office stationery that you carry around in your pocket because it smells of all the lilacs in Ohio.”
—Billy Wilder (b. 1906)
“Suddenly I’m not half the girl
I used to be.
There’s a shadow hanging over me . . .
From me to you out of my electric devil....”
—Anne Sexton (1928–1974)
