How do rainforests make their own rain?

In tropical rainforests, trees and other plants move large amounts of water from the soil into the air through transpiration. This moisture adds humidity, which cools and condenses into clouds under the right conditions. The Amazon rainforest is famous for creating much of its own rainfall, helping maintain the wet climate that supports it. Trees also shade the ground and slow evaporation, which helps preserve water in the ecosystem. This moisture recycling makes intact forests especially important for regional weather patterns.
