The lower part of this tornado is surrounded by a translucent dust cloud, kicked up by the tornado's strong winds at the surface.
Large single-vortex tornadoes can look like large wedges stuck into the ground, and so are known as "wedge tornadoes" or "wedges".
The "stovepipe" classification is also used for this type of tornado if it otherwise fits that profile.
These spiraling columns of air frequently develop in tropical areas close to the equator and are less common at high latitudes.
Other tornado-like phenomena that exist in nature include the gustnado, dust devil, fire whirl, and steam devil.
The most extreme tornadoes can attain wind speeds of more than 300 miles per hour (480 km/h), are more than two miles (3 km) in diameter, and stay on the ground for dozens of miles (more than 100 km).
Various types of tornadoes include the multiple vortex tornado, landspout, and waterspout.The Fujita scale rates tornadoes by damage caused and has been replaced in some countries by the updated Enhanced Fujita Scale.An F0 or EF0 tornado, the weakest category, damages trees, but not substantial structures.Several tornadoes are sometimes spawned from the same large-scale storm system.If there is no break in activity, this is considered a tornado outbreak (although the term "tornado outbreak" has various definitions).Waterspouts are characterized by a spiraling funnel-shaped wind current, connecting to a large cumulus or cumulonimbus cloud.They are generally classified as non-supercellular tornadoes that develop over bodies of water, but there is disagreement over whether to classify them as true tornadoes.This results in the formation of a visible funnel cloud or condensation funnel.There is some disagreement over the definition of a funnel cloud and a condensation funnel.An F5 or EF5 tornado, the strongest category, rips buildings off their foundations and can deform large skyscrapers.The similar TORRO scale ranges from a T0 for extremely weak tornadoes to T11 for the most powerful known tornadoes. The funnel is the thin tube reaching from the cloud to the ground.
