Savage Planet: Deadly Skies - How Lightning Forms Lightning comes from thunderclouds, known as cumulonimbus, which are created when hot moist air rises into the atmosphere and condenses. Hot air rises when heated by the sun, carrying water vapor into the sky. As it rises, the hot air mingles with colder air, and the moisture condenses into water droplets. Clouds are created when these water droplets become visible. The droplets increase in size as the cloud grows and eventually become so heavy that they fall as rain. Thunderclouds are large, anvil-shaped masses that can stretch miles across at the base, and reach 40,000 feet or more into the atmosphere.
