That is the most common direction in which tornadoes travel, but they can move in any direction.
True. Doppler radar can detect tornadoes.
Tornado-like whirlwinds made of fire are called firewhirls. Meteorologists do not consider them to be true 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.
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.
Tornadoes can occur in many parts of the world, not just in Tornado Alley in the central United States. They can form in any region where the right atmospheric conditions are present, although Tornado Alley does have a higher frequency of tornadoes.
It can be either. Tornadoes can move faster than 40 mph, but usually don't.
True. Doppler radar can detect tornadoes.
Tornadoes normally rotate cyclonically in direction: - counterclockwise in the northern hemisphere - clockwise in the southern hemisphere But while large-scale storms always rotate cyclonically due to the Coriolis effect, thunderstorms and tornadoes are so small that the direct influence of the Coriolis effect is inconsequential. Supercells and tornadoes rotate cyclonically in numerical simulations even when the Coriolis effect is neglected. Low-level mesocyclones and tornadoes owe their rotation to complex processes within the supercell and ambient environment. Approximately 1% of tornadoes rotate in an anticyclonic direction. Typically, only landspouts and gustnadoes rotate anticyclonically, and usually only those which form on the anticyclonic shear side of the descending rear flank downdraft in a cyclonic supercell. However, on rare occasions, anticyclonic tornadoes form in association with the mesoanticyclone of an anticyclonic supercell, in the same manner as the typical cyclonic tornado, or as a "companion tornado," either as a satellite tornado or associated with anticyclonic eddies within a supercell.
Tornadoes follow a predictable pattern of formation and dissipation.
It has recently been found that there are vortices on the sun that superficially resemble tornadoes, but they are not true tornadoes.

Yes. The southwest is best known for its deserts.

The winter in the northeast of the United States is cold with snow. This is also true of the northeast of the world, namely northern Asia.
Tornadoes occur in other countries besides the US. However, the US heartland has ideal conditions for tornadoes.
