Phantom Rain That Never Falls

In especially hot and dry climates, it can rain without water ever hitting the ground. This phenomenon is called virga, or "phantom rain," and resembles tails hanging below a cloud from afar. Because deserts have high temperatures and low humidity, virga tends to occur, the rain evaporating high in the sky.
