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.

Is an updraft the middle of a tornado?
No, an updraft is not the middle of a tornado. An updraft is the rising current of air within a storm or tornado that fuels its rotation and strength. The middle of a tornado is called the "eye," which is a calm and clear area surrounded by the rotating winds.
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.
Why would updraft start to rotate?
When winds intensify, the force released can cause the updrafts to rotate
What part of the storm does a tornado form in?
A tornado usually forms from a mesocyclone, which occurs in the updraft or rear portion of some thunderstorms.
What causes the rising air from a tornado to rotate?
Most tornadoes develop from a larger circulation called a mesocyclone, which can be found in some thunderstorms. The mesocyclone gets its rotation from horizontally rolling air masses getting pulled into the thunderstorm updraft,

How does wind make up a tornado?
A tornado is a very intense vortex of air. Air spirals in towards the low pressure at the center of the tornado and is then drawn upwards. Most tornadoes form from a larger vortex called a mesocyclone, which is part of the updraft of some thunderstorms. At some point this vortex tightens and intensifies to form a tornado.
Does a tornado have a very strong updraft at its center?
Usually a tornado will have a strong updraft at its center, but some tornadoes sometimes have a gentle downdraft at the center instead while the powerful updraft is limited to the area surrounding it. This is analogous to the eye and eyewall of a hurricane.
In a tornado the air spirals mostly vertically?
No, the rotation of a tornado is stronger than its updraft.
Why would updraft start to rotate?
When winds intensify, the force released can cause the updrafts to rotate
How does the air chase itself in a tornado?
A tornado forms from the rotating updraft of a thunderstorm. The updraft of the tornado creates low pressure that causes air to spiral inward (usually counterclockwise int he northern hemisphere and clockwise in the southern) and then upward.
How does air get in a tornado?
Air enters a tornado through the updraft at the storm's center. The intense rotating updraft pulls in surrounding air, creating a spiraling column of wind. This process continues to strengthen as more air is drawn in, fueling the tornado's development.
Why does a tornado move up instead of down?
Air in a tornado moves up because the tornado forms in the updraft portion of a thunderstorm.
How does a tornado ends?
How a tornado ends is not fully understood. It is thought, however, that cold air coming out of a thunderstorm (called outflow) undercuts the mesocyclone, the rotating updraft that drives the tornado. This chokes off the supply of warm air that feeds the updraft.
What element of thunderstorms causes a tornado?
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.
What part of the storm does a tornado form in?
A tornado usually forms from a mesocyclone, which occurs in the updraft or rear portion of some thunderstorms.
