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.

What are the three steps of a tornado?

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.


Can a tornado's rotation be reversed?

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).


Does rain help a tornado?

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.


How does a tornado take a move across an area?

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.


How is a tornado created in simple words?

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.
