Only by a technicality. Most tornadoes do not actually kill anyone; only about 2% of tornadoes are killers. Only a handful of people have been killed by dust devils, but that still means there have been a few dust devils with a death toll of 1, while there have been many tornadoes with death tolls of zero.
Aside from that, though, tornadoes are deadlier. Dust devils are far more common than tornadoes, but only a handful of people have been killed by them, and injuries generally only occur once every few years. By contrast tornadoes kill dozens of people and injure hundreds in a normal year.
No, a dust devil is not a mini tornado. Dust devils are small, rapidly rotating columns of air that form under sunny conditions, while tornadoes are large, violent rotating columns of air that form during severe thunderstorms. Dust devils are typically harmless and short-lived compared to tornadoes.
They aren't. Tornadoes and dust devils are two different things. A tornado is a violent vortex of wind that develops during a severe thunderstorm. A dust devil is a much weaker whirlwind that often forms under clear skies.
A tornado is a type of whirlwind characterized by a violently rotating column of air extending from a thunderstorm to the ground. A whirlwind is a rotating column of air but can vary in size and strength, while a tornado is a specific and more powerful type of whirlwind.
A "dirt devil" more properly called a dust devil is a vortex that forms at ground level as a result of the sun heating the ground. These whirlwinds may look somewhat like tornadoes, but they are not. Unlike tornadoes, which require thunderstorms to form, dust devils almost always form in sunny weather. They are also weaker than tornadoes, with the very strongest dust devils barely producing winds equivalent to an EF0 tornado.
Dust devils are more likely to form on hot, sunny days when the ground is dry and the air near the surface is rapidly heated. This causes the air to rise quickly, creating a spinning column of air that picks up dust and debris. Flat, open areas with minimal wind are also more conducive to dust devil formation.
By volume a tornado is probably more than 99% air. The rest is condensation and, in some cases, dust and debris.
No, although hot weather may result in dust devils it is not directly conducive to tornado formation. Tornadoes need thunderstorms called supercells to form. Tornadic storms and other severe weather form along cold fronts (which cause a temperature drop) more often than warm fronts.
They aren't. Apart from the extremely deadly 2011 tornado season, annual tornado death tolls in the U.S. have actually been decreasing due to improved warning systems. However, some warn that tornado fatalities could rise as populated areas grow, giving tornadoes more targets in which deaths may occur.
One is a violently rotating column of air and debris that can tear a path of destruction over a mile wide with wind speeds well over 200 mph. The other is a well known brand of vacuum cleaner and vacuum cleaner accessories. Check out their homepage at the related link; they have some fantastic online sales at times.
A tornado is a violently rotating column of air that is in contact with the cloud base of a thunderstorm and the ground. A funnel cloud is a potential tornado that extends from the base of a thunderstorm, but the circulation does not reach the ground. A waterspout is a tornado or a tornado like vortex that occurs on a body of water. Most waterspouts form by a different mechanism for typical tornadoes and are usually weaker. A dirt devil, more commonly called a dust devil, is a small vortex that forms at ground level on hot, sunny days. Unlike a tornado, funnel cloud, or most waterspouts, a dust devil is an independent whirlwind that is not associated with a thunderstorm and does not connect to any cloud base. Dust devils are much weaker than tornadoes.
The gainseville is a tornado that occured in April 6,1936.This deadly monster killed 203 people and injured 1,600 more. It tore up four blocks and destroyed 750 homes
In most if not all cases a tornado would be more than 99% air. If a tornado is not lifting any notable amounts of dust or debris might be 99.9995% air by volume while most of the rest is water droplets. It becomes more difficult for tornadoes that contain large amounts of dust and debris, but the vast majority of the volume is still air.
