Thunderstorm

Thunderstorm

Thunderstorms form when particularly warm, moist air rises into cold air above land or sea. As the humid air rises, water vapour condenses, forming huge cumulonimbus clouds.
Lightning is caused when electrical energy is released from the cloud and passes through the air to another point with the opposite charge, such as the ground. Light is produced that travels from the ground up to the cloud, known as lightning. Thunder is caused by air that has expanded very quickly due to heat. [VH] {WC}
A thunderstorm consists of rainclouds and precipitation but its defining feature is lightning and thunder.
Thunderstorms are loud and can be heard as far away as 24 km. The lightning that comes with them is very bright. This combination can be frightening and even deadly. [AM] {GC} {WW}
