Since a tornado is a severe weather event, the formation of one would be studied in meteorology.

The formation of a tornado is called tornadogenesis.
The rotation in a supercell is what leads to tornado formation.

A tornado watch is issued when general conditions across a region are favorable for the formation of tornadoes. Such an advisory does not indicate an imminent tornado threat for any given location; that would warrant a tornado warning.

You would say "Will be examined."
It is still just a tornado. However, it would be quite unusual to have an actual tornado go through an area where there is snow on the ground, as such conditions would generally be be too cold for tornado formation. Sometimes, though, you can get small whirlwinds that usually result from wind interacting with trees, buildings, and terrain. These are not tornadoes, but harmless eddies. If they lift snow into the air they are somtimes called snow devils.
The main characteristic is the rotation updraft or mesocyclone, which provides the spin that becomes a tornado. Another factor is that, in a supercell, the downdraft is separated from the updraft that powers the storm, and so does not interfere with it like it would in an ordinary thunderstorm.
a tornado warning would be issued if it is in your county and a tornado watch if it is out of your county.
No, you cannot stop a tornado with another tornado. The two tornadoes would simply merge and form a larger tornado.
