These whirling atmospheric vortices can generate the strongest winds known on Earth: wind speeds in the range of 500 km (300 miles) per hour have been measured in extreme events. Sometimes the spinning column of air lifts off the ground, then touches down again some distance along its path. The updraft will begin to rotate if winds vary sharply in speed or direction.
