Where does a tornado start from?
A tornado starts from the mesocyclone, or strong, rotating updraft, of a supercell. A supercell is a type of especially powerful, rotating thunderstorm.
Why does an updraft in a tornado rotate?
There are a couple ways in which a tornado can form, both involving the updraft of a thunderstorm. In the classic model of tornado formation, the updraft of the thunderstorm starts rotating due to interaction with wind shear (differences in wind speed and direction with altitude) and may be influenced by the general rotation of the parent storm system. The tornado then develops from this rotating updraft. In the other model, by which landspouts and most waterspouts form, a broad-level circulation at the ground gets caught in the updraft of a developing thunderstorm, becoming narrower and more intense.
Why do tornadoes have a spiral shape?
Tornadoes take on a spiral shape because the winds in them spin and move upward. This is because tornadoes originate from the rotating updraft of a supercell thunderstorm. The updraft gets this rotation from wind shear.
Why does hail and tornadoes usually occur at the same time?
Hail forms in the strong updraft of a severe thunderstorm, which keeps the hailstones airborne as they form. Tornadoes require a specific type of severe thunderstorm called a supercell. The tornado itself forms from a strong, rotating updraft which can also generate hail.
Why would a tornado start rotate?
Tornadoes rotate because they form from a larger mass of rotating air. In most cases this rotation comes from a mesocyclone, the rotating updraft of a supercell thunderstorm. The mesocyclone can tighten and intensify to produce a tornado. Some tornadoes form from a broad, weak circulation at ground level, which gets caught in a thunderstorm updraft and turned into a narrower but stronger vortex.
What is a super cell thunderstorm?
A thunderstorm with a deep, rotating updraft.
Is a rotating updraft or supercell required for all thunderstorms to form?
No. All thunderstorms require an updraft, but that updraft does not need to rotate. A supercell is not a rotating updraft, but rather a particular kind of thunderstorm with a rotating updraft.
Which of the following is not a condition requiered for all thunderstorm to form?
A rotating updraft, or supercell
Where does a tornado start from?

Can a tornado be caused by thunderstorm?
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.
What is the difference between a thunder cell and a supercell?
A supercell is a kind of thunderstorm cell. A thunderstorm cell consists of a convective unit with its own updraft and downdraft. A supercell is the most powerful type of storm cell with a strong, rotating updraft and distinct updraft and downdraft regions.
Why does an updraft in a tornado rotate?

Why do tornadoes need thunderstorms to create?
In simple terms, only a thunderstorm can concentrate the energy needed to form a tornado. Most tornadoes from from a thunderstorm with a rotating updraft. Others develop from interactions between turbulence and a non-rotating updraft. Other varieties of whirlwind can develop without thunderstorms, but they are not nearly as strong as tornadoes.
How is a supercell turned into a mesocyclone?
A supercell does not become a mesocyclone, it is a storm with as mesocyclone inside it.A mesocyclone is the rotating updraft of a supercell that forms when wind shear is turned vertical by a thunderstorm's updraft.
Why do tornadoes happen in nature?
To be put briefly: rolling air called wind shear gets turned vertical by a thunderstorm's updraft. This starts the storm rotating, turning into a supercell. Under the right conditions this rotating updraft, called a mesocyclone, can tighten and intensify into a tornado.
What is a supercell hailstorm?
A hailstorm is a thunderstorm that produces hail, a form of hard, frozen precipitation. A supercell is the most powerful class of thunderstorm on Earth, characterized by a strong, rotating updraft. Because of the strong updraft, supercells are the most likely kind of storm to produce damaging hail.
Why does the air pressure go down when a tornado is near?
A tornado develops when the rotating updraft of a thunderstorm becomes focused on a smaller area. The updraft of the tornado draws air upwards, creating a center of low pressure.
