Usually a supercell
Yes. A tornado can be though of as part of a larger parent thunderstorm, though most thunderstorms do not produce tornadoes.
A storm can't turn into a tornado, it a thunderstorm can produce one.
A supercell.
Yes, in fact a thunderstorm is the only thing that can produce a tornado.
One indicator that a thunderstorm may produce a tornado is the presence of a rotating wall cloud. This is a large, lowering cloud that exhibits rotation at the base of a thunderstorm. When combined with other factors such as strong winds and changing weather conditions, it may increase the likelihood of tornado formation.
Rotation.
A tornado is most likely to be produce from a type of thunderstorm called a supercell.
When a tornado warning means that a tornado has been spotted or detected or if a thunderstorm may produce a tornado at any moment.
A tornado warning is an advisory that is issued when a tornado has either been spotted or detected or that a thunderstorm in the area is likely to produce a tornado soon.
Yes, a severe thunderstorm can create the conditions necessary for a tornado to form. Thunderstorms with strong updrafts and rotation can produce tornadoes when other factors align, such as atmospheric instability and wind shear.
The transformation from a thunderstorm cloud to a tornado can occur rapidly, typically within a matter of minutes. This process involves the development of a severe thunderstorm with rotation that can quickly strengthen and produce a tornado.
Not all severe thunderstorms produce tornadoes. While hail can be a supportive factor in tornado formation, other conditions such as wind shear and atmospheric instability are also necessary. So, a severe thunderstorm without hail could still potentially produce a tornado if other conditions are met.
