What is a tornado?

A tornado is defined as a rapidly rotating column of air that extends from the base of a cloud down to the ground. This unique characteristic is critical in distinguishing tornadoes from other meteorological phenomena. Tornadoes often form in severe thunderstorms and are known for their intense winds, which can cause significant damage to structures and landscapes.

The definition emphasizes the dynamic and violent nature of a tornado, as well as its connection to severe weather conditions. Understanding this distinction is essential for recognizing the risks associated with tornadoes and for taking appropriate safety measures during severe weather events. The other options describe different atmospheric phenomena that do not exhibit the same characteristics as a tornado. For instance, static air masses typically lead to stable weather with minimal movement, while high-altitude wind patterns and rain associated with weak storm systems are not related to the violent rotation and ground contact that defines a tornado.
