Which type of thunderstorms is known for traveling at high speeds?

Frontal thunderstorms are associated with the movement of weather fronts, where a cold front collides with warm, moist air. This interaction can lead to the rapid development and propagation of thunderstorms, often resulting in storms that can travel at higher speeds compared to other types. The temperature difference and the momentum of the frontal system contribute to the velocity of these storms.

In contrast, severe thunderstorms typically refer to the intensity of the phenomena rather than their speed of travel, orographic thunderstorms are primarily triggered by terrain features which can limit their forward motion, and air mass thunderstorms are generally more localized and may not exhibit the same high-speed characteristics.
