Which type of thunderstorm is known for having the fastest movement?

Frontal thunderstorms are known for their fast movement due to their association with weather fronts. These thunderstorms form when air masses with differing temperatures and humidity converge, leading to a rapid lifting of the warm, moist air over the cooler air. The dynamics of frontal systems can create strong winds, contributing to the swift movement of these thunderstorms across the landscape.

In contrast, heat thunderstorms tend to develop over land areas on hot days due to localized heating. These storms often move more slowly because their development is closely tied to the local thermal conditions. Orographic thunderstorms typically occur when moist air rises over mountains, leading to heavy precipitation but generally do not have the same rapid movement as frontal thunderstorms. Severe thunderstorms can indeed be fast-moving but encompass various storm types, including fronts, making them less specific than frontal thunderstorms when discussing speed. Therefore, frontal thunderstorms stand out for their quick advancement compared to other types.
