Thunderstorms are caused by a collision of warm air and cold air. A thunderstorm is a cloud formation where large amounts of water undergoes a cycle of condensation, freezing then revaporizating as the currents of vapor within the cloud rises and falls. This produces static electricity which discharges as lightning. Thunderstorms are caused by a collision of warm air and cold air.

A thunderstorm, also known as an electrical storm, a lightning storm, or a thundershower, is a type of storm characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere known as thunder. Thunderstorms occur in association with a type of cloud known as a cumulonimbus.ry thunderstorms, with no precipitation, can cause the outbreak of wildfires with the heat generated from the cloud-to-ground lightning that accompanies them. Several methods are used to study thunderstorms, such as weather radar, weather stations, and video photography.
