<u>Answer:</u> "Tornado" is a form of severe weather depicted in the given image.
<u>Explanation:</u>
A tornado is a rapidly spinning mass of air reaching down to the ground from the center of a thunderstorm. Tornadoes can completely destroy well-made buildings, uproot trees and hurl objects like lethal missiles through the air. Several types of tornadoes include multiple vortex tornado, landspout, and waterspout.
Tornadoes occurs very often in North America (especially in central and southeastern regions of the United States known as tornado alleys), southeastern South America, Southern Africa, Northwestern and Southeastern Europe, Bangladesh and adjacent eastern India, Western and Southeastern Australia and New Zealand.
Tornadoes can be detected before or as they occur with the help of Pulse-Doppler radar by recognizing patterns in data on velocity and reflectivity like hook echoes or debris balls, also by storm spotter effort.
