Tornadoes are typically produced by thunderstorms called supercells.
Of these, tornadoes have the shortest duration.
Storms of all kinds are generally associated with low pressure.
In the United States, it is severe if there is hail larger than 1" in diameter, wind gusts greater than 58 mph, or a tornado.
A tornado warned storm is a thunderstorm for which a tornado warning has been issued, meaning that the storm is producing rotation that can spawn a tornado.
A tornado comes from a type of storm called a rotating thunderstorm, but is not a storm, itself.
The rotating updraft within a thunderstorm, known as a mesocyclone, is responsible for creating the conditions that can lead to a tornado. When this rotating air column tightens and extends to the ground, it can form a tornado.
A tornado is a violent microscale circulation with a low pressure center and forms from a thunderstorm.
A thunderstorm will cause a tornado. The thunderstorm clouds are the Cumulonimbus clouds. The majority of thunderstorms that produce tornadoes are in a special class called supercells. These are the most powerful thunderstorms on earth and are noted for having a rotating updraft called a mesocyclone.
The air inside a tornadic thunderstorm (a storm that produces a tornado) does spin. But it is that spinning air that causes the tornado, rather than the tornado starting the air spinning.
Tornadoes usually form from a kind of thunderstorm called a supercell.
Tornadoes are most often associated with a kind of thunderstorm called a supercell.
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 descends from the base of a thunderstorm.
a tornado is formed by a thunderstorm
No. A tornado is a very intense kind of whirlwind but most whirlwinds are not tornadoes. By definition a tornado is associated with a thunderstorm and connects to both the ground and the cloud base.
Hurricanes themselves are much larger than any thunderstorm or tornado.
Tornadoes are most often produced by a kind of thunderstorm called a supercell.
