tornado family

A tornado is a violently rotating column of air that develops within a thunderstorm and touches the ground. While most tornadoes are short-lived and produce a single vortex, some storms can generate a tornado cyclone, a rotating core from which multiple tornadoes can form. This sequence of tornadoes from a single storm is known as a tornado family.12

Tornado families typically consist of two or three tornadoes, but can be larger. In rare instances, a tornado cyclone can remain stable for hours, producing a single, long-lasting tornado with an extensive damage path, referred to as a long-track tornado. Tornado outbreaks involve multiple tornadoes occurring over a region, often due to thunderstorms within the same weather system. These outbreaks are categorized by the number of tornadoes and the geographic area affected.23
