Which type of thunderstorm is noted for its speed?

Frontal thunderstorms are specifically associated with weather fronts, which involve the rapid lifting of warm, moist air over a cold front. This process can lead to the quick development of thunderstorms. Frontal boundaries often create significant contrasts in temperature and humidity, which can lead to vigorous convection and consequently, faster-moving storms.

In contrast, other types of thunderstorms, such as multi-cell or single-cell thunderstorms, typically have varied characteristics that do not prioritize speed as a notable feature. Multi-cell thunderstorms can produce a series of storm cells that may move at a moderate pace but often evolve over time rather than being noted for their speed. Single-cell thunderstorms, also called pulse thunderstorms, are generally short-lived and isolated but don’t necessarily move quickly either.

Thus, frontal thunderstorms stand out due to their association with faster-moving boundary interactions in the atmosphere.
