A thunderstorm does not become a tornado, it producesone.
In order to produce a tornado a storm first needs a strong, rotating updraft called a mesocyclone. A storm with this feature is called a supercell. The rotation in a mesocyclone the tightens, intensifies, and extends towards the ground, becoming a tornado.
How this intensification occurs is not fully understood, but it is believed that a downdraft at least plays a role by wrapping around the mesocyclone and forcing it into a tighter circulation.
A supercell is the kind of thunderstorm most likely to produce a tornado.
yes and no. A thunderstorm can produce a tornado but does not actually become one. All tornadoes are produced by thunderstorms.

One of the strongest indicators that a thunderstorm might produce a tornado is rotation in the clouds.
Tornadoes are started when wind shear starts air masses rolling in what is called horizontal vorticity. This rolling air movement can be turned vertical by the updraft of a thunderstorm, which then takes on the rotation to become a mesocyclone. Under the right conditions a downdraft can descend from the back of the storm and wrap around the mesocyclone. This can tighten and intensify the rotation and br9ing it down to the ground to produce a tornado.
Yes, a tornado can come from a thunderstorm. In fact, a tornado cannot be caused by anything other than a thunderstorm. One key facotrs is that the thunderstorm must have a rotating updraft.
Yes. In fact a thunderstorm is the only thing that can cause a tornado.
A supercell is the kind of thunderstorm most likely to produce a tornado.
A tornado/thunderstorm watch means that weather conditions are good for tornado/thunderstorm. A tornado/thunderstorm warning, however, means that conditions are extreme and a thunderstorm or tornado is likely. Conditions for either storm are very good at this stage.
a tornado is formed by a thunderstorm
A tornado descends from the base of a thunderstorm.
Hurricanes themselves are much larger than any thunderstorm or tornado.
A parent thunderstorms is a thunderstorm that produces some other event. This is often used when refering to tornadoes. A storm that produces a tornado is that tornado's parent thunderstorm.
Yes. A tornado can be though of as part of a larger parent thunderstorm, though most thunderstorms do not produce tornadoes.
The tornado is part of the updraft of a thunderstorm that has become focused and very intense. The pressure inside a tornado is lower than in the surroundings, so air is dran into the tornado and then upwards by the updraft.
well the thunderstorm builds to a super cell which is a sever thunderstorm then all it needs is a rotation
yes and no. A thunderstorm can produce a tornado but does not actually become one. All tornadoes are produced by thunderstorms.
