Weather Tidbits: Orographic Lifting

This Weather Tidbits breaks down the role of mountains and precipitation. Orographic lifting occurs when moist, warm air hits the mountain and is forced upwards, which cools. The cooling air will cause moisture to condense into precipitation over the higher terrain. Once that cooler air passes over the mountain; it sinks and the air dries and warms. The leeward or downward side of the mountain will have less precipitation creating a rain shadow; with this common setup occurring in the Western United States.
