There are a few ways. Most strong tornadoes from from the rotating updraft or mesocyclone of a supercell, which tightens and intensifies under certain conditions to form a tornado. Weaker landspout tornadoes form when low-level rotation gets caught in the updraft of a developing thunderstorm, which causes it to stretch upward, tighten, and intensify. Still others spin up along the leading edge of a squall line.
The three steps of a tornado are formation, maturity, and dissipation. During the formation stage, a rotating column of air develops. In the maturity stage, the tornado reaches its maximum intensity, causing the most damage. Finally, during the dissipation stage, the tornado weakens and eventually ceases to exist.
An individual tornado cannot change the direction that it rotates, however in rare cases a tornado may rotate in the opposite direction from what is norm (nearly all tornadoes rotate counterclockwise in the northern hemisphere, and clockwise in the southern).
No, rain does not help a tornado form. Tornadoes are formed by severe thunderstorms with specific atmospheric conditions, such as wind shear and instability. Rain can occur before, during, or after a tornado, but it is not a contributing factor to the formation of a tornado.
It depends on the size of the tornado and how fast it's moving. Most tornadoes are not over any sport for more than a few seconds, but a large tornado may be over an area for a minute or more. In one instance a tornado remained on the same spot for 90 minutes.
A tornado forms from thunderstorms. The thunderstorm starts turning because the wind at different heights is going in different directions and at different speeds. Sometimes this turning in the storm gets focused into a smaller area and starts spinning faster, becoming a tornado.

Partially. A tornado warning means that a tornado is likely to form or already has formed.
A tornado warning is a higher level of alert, often meaning that a tornado has formed.
waterspouts
A waterspout it a tornado that forms on a body of water. It looks like a land formed tornado but on a smaller scale.
If a tornado has formed in the U.S. chances are it will be detected by Doppler radar.
A tornado is a kind of vortex so yes, in some ways.
The last tornado in England was formed on the Wednesday 28th of April 2012 in Essex!
The noun clause is 'why the tornado formed', functioning as the object of the verb 'understands'.
