How are tornadoes caused?
Tornadoes develop from severe thunderstorms in warm, moist, unstable air along and ahead of cold fronts. Such thunderstorms also may generate large hail and damaging winds. When intense springtime storm systems produce large, persistent areas that support tornado development, major outbreaks can occur.
What is tornado in simple words?
A tornado is a tube of violently spinning air that touches the ground. Wind inside the tornado spins fast, but the actual ‘circle’ of wind around them is huge. This makes tornadoes very dangerous.
How do tornadoes start and stop?
Inside the wall cloud, a funnel cloud forms and extends towards the ground. It causes air on the ground to rotate, and begin to rip up the earth. When the funnel cloud meets the churning air near the ground, it becomes a tornado. When the updrafts lose energy, the tornado does too, and it slowly disappears.
