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.

The storm itself can either be a single cumulonimbus cloud, a cluster of several thunderstorms, or a line of thunderstorms. In order for thunderstorms to form, there needs to be: 1  Moisture-to form clouds and rain. 2  Unstable air-warm air that can rise rapidly.3  Lift-cold or warm fronts, sea breezes, mountains or the sun's heat are capable of lifting air to help form thunderstorms.n the western half of the peninsula in a typical year, there are over 80 days with thunder and lightning.
