A tornado is a violently rotating column of air that extends from a thunderstorm cloud to the ground. These powerful weather systems form through the complex interaction of severe atmospheric conditions, most notably strong vertical wind shear and atmospheric instability. The intense rotation is typically associated with a mesocyclone within the parent storm structure. Tornadoes can vary significantly in size and intensity, with their structure and destructive potential governed by specific atmospheric dynamics. Their occurrence is a hallmark of severe weather regions and requires distinct meteorological conditions for genesis.
