Both tornadoes are small-scale vortices of wind in which air spirals in toward a localized center of low pressure and then spirals up. Both produce strong winds over small areas, though tornadoes are far stronger. The formation of both depends on the conservation of angular momentum; they form when a larger, less intense circulation tightens and intensifies. The key difference between tornadoes and dust devils is that dust devils form from surface convection resulting from direct heating of the ground while tornadoes are driven by the movement of air in a thunderstorm.

Which planets have red dust tornadoes?
True tornadoes only form on earth, as far as scientists know. These may become red if they encounter red dust. The planet Mars, had red dust devils. Dust devils resemble tornadoes but they are not actually tornadoes.
Is it possible for a tornado to come with the sun out?
Tornadoes can only form during thunderstorms, though sometimes the sun may peak through from the side to illuminate a tornado. Other than that, no. Sometimes dust devils will develop on sunny days. Dust devils are whirlwinds that look rather like tornadoes, but they are not. Dust devils are usually harmless.
Are dust devils common?
Dust devils are common wherever there are wide expanses of flat, open land, with exposed areas having little vegetation to protect the soil and sand. Crosswinds whip across these areas, causing the formation of miniature tornadoes which can, in fact, grow quite large. Dust devils are found on all continents except for Antarctica, and are known by different names. In Australia, for example, they are commonly called willy-willies.
What is the name for a tornadoes that forms in the desert?
The tornado-like whirlwinds that often occur in deserts are called dust devils. They are not actually tornadoes. On rare occasions, true tornadoes do occur in deserts, associated with infrequent severe thunderstorms.
What do you call a sand storm like a tornado?
A sandstorm with rotating winds is often called a "dust devil." Dust devils are smaller in scale compared to tornadoes and are typically formed in arid regions with loose sediments like sand or dust.
What makes dust devils different than tornadoes?
Dust devils form in sunny weather while tornadoes require thunderstorms to form. Dust devils are much weaker and generally smaller than tornadoes as well.
Which planets have red dust tornadoes?
True tornadoes only form on earth, as far as scientists know. These may become red if they encounter red dust. The planet Mars, had red dust devils. Dust devils resemble tornadoes but they are not actually tornadoes.
How many tornadoes have there been in Africa?
yes tornadoes and dust devils are common in Africa
Why are tornadoes called dust devils?
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.
Can a dust devil develop into a tornado?
No. Dust devils are whirlwinds that form from low-level convection in the absence of a thunderstorm. Tornadoes form from thunderstorms. However, on rare occasions dust devils can cause minor damage with winds comparable to those of an EF0 tornado. Landspout tornadoes can sometimes look rather like dust devils.
Does the Death Valley have tornadoes?
Yes. Death valley can get tornadoes, but they are very rare. Dust devils are common though.
Can dust devils pick you up?
Dust devils are not strong enough to pick up people. They are relatively weak compared to tornadoes and are usually harmless. However, it is still important to exercise caution when encountering dust devils.
Are there really fire tornadoes?
Sort of. There are firewhirls, vortices of smoke of fire that resemble tornadoes. However, they technically are not tornadoes and have more in common with dust devils.
Can dust devils be more deadly than a tornado?
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.
Does drought cause tornadoes?
No. In dry, dusty conditions you may see whirlwinds called dust devils. Dust devils are not tornadoes, though they may look somewhat like them. They are usually harmless. Tornadoes require thunderstorms in order to form, so you are actually less likely to see tornadoes during a drought than at other times.
Where should you go if there is a dust devil tornado?
Just watch and enjoy. Dust devils are not tornadoes. They are much weaker and are usually harmless.
What will happen if a sand tornado hits a desert?
It will lift up sand and dust. "Sand tornadoes," which are technically dust devils rather than actual tornadoes, usually occur in deserts anyway.
