The tornado originates from a larger circulation within the parent storm cell called a mesocyclone. This gets constricted by a downdraft within the storm, causing it to tighten, intensify, and extend toward the ground. As the developing vortex extends toward the ground, it draws in air from underneath. However, once it reaches the ground, this is no longer possible, and so pressure at the center drops. This drop in pressure increases wind speed in the vortex as it draws in air from the sides, accelerating it to great speeds. The vortex is now a tornado.

How can a tornado form in space?
Tornadoes cannot form in space. A tornado is a vortex of air. There is no air in space.
What happens before a tornado occurs?
Before a tornado occurs, the atmosphere needs to be unstable, with warm, moist air at the surface and cold, dry air aloft. Wind shear is also crucial, as it creates the rotation necessary for a tornado to form. Storm systems or supercell thunderstorms often provide the ideal conditions for tornado development.
Where does a tornado start from?
Tornadoes typically form from severe thunderstorms in a weather system where warm, moist air collides with cool, dry air. The spinning motion starts when wind directions and speeds vary at different altitudes, creating a horizontal rotation. When this rotation is tilted vertically by rising air, a tornado can develop and touch down on the ground.
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.
Can a tornado form from just hot air?
No!
What can form with little or no warning a tornado or a hurricane?
That would be a tornado. Once the process starts, a tornado can form in a matter of seconds. Hurricanes, by contrast, usually take several days to form and are easy to track.
A tornado starts out as a what?
A tornado starts out as a funnel cloud.
It can change into a water spout?
A water spout is a type of tornado that forms over water. It happens when a tornado crosses over a body of water and starts pulling up water into the air. The spinning motion of the tornado creates a funnel-shaped cloud with water droplets.
What happens to living and non living things if a tornado happens?
The area in which the tornado happens can erode the area away cause the animals that lived there to have no home or die of the tornado
What happens to sucrose molecules when heated?
new molecules starts to form
A tornado warning means that a tornado is likely to form?
Partially. A tornado warning means that a tornado is likely to form or already has formed.
What happens when 2 tornadoes combine?
When two tornadoes combine, it is known as a tornado outbreak. The resulting tornado can become larger, stronger, and more destructive as it merges with the energy and circulation of the other tornado. The combined tornado can create a wider path of destruction and pose an increased threat to affected areas.
Can a tornado form in England?
well i think a tornado can form anywhere
Is it true that a tornado warning means that a tornado might form?
No. A tornado warning means that a tornado is likely to form or has already been spotted.
What happens in the second trimester?
the foetus gets bigger and starts to form into a baby
Where do people go when a tornado starts?
a shelter
What exactly is a tornado and briefly explain how a tornado forms?
A tornado is a violent swirling funnel that usually happens in very intense thunderstorms. They form when thunderstorms start rotating due to interactions with wind shear. This rotation then tightens and intensifies to form a tornado.
