Which weather system is distinguished by a rotating column of air?

The choice of a tornado is accurate because a tornado is characterized by a rotating column of air that extends from a thunderstorm to the ground. This rotation is a result of strong wind shear in the atmosphere, which can lead to the development of a funnel-shaped cloud with highly aggressive updrafts. Tornadoes can form rapidly and are often associated with severe weather events like supercell thunderstorms, making them particularly dangerous due to their localized but intense nature.

While thunderstorms can produce rotation and may contain features like gust fronts, they do not inherently involve a concentrated and sustained rotating column of air like a tornado does. Hurricanes also involve rotation, but on a much larger scale, as they are systems that form over warm ocean waters and involve complex wind patterns and a self-sustaining structure. Cold fronts, on the other hand, are boundaries between colder and warmer air masses and do not feature a rotating column of air in the same way that tornadoes do.
