Rain shadow The air mass has now lost most of its moisture, which condensed out and fell as precipitation on the windward side. As the air descends the leeward side of the mountain, it compresses. Because heat was added during the condensation process, the air mass warms quickly, and can be warmer than it was when it originally ascended the mountain. Temperatures can be as much as 50°F warmer than it was before it started its ascent. The lack of moisture, and rain, on the leeward side of a mountain is known as its "rain shadow." |
