HOW ARE TORNADOES FORMED?
There are many disasters and one of them is a tornado.
A tornado or “Smerch” is an atmospheric vortex that arises in a cumulonimbus
(thunderstorm) cloud and spreads down, often to the very surface of the earth,
in the form of a cloud arm or trunk with a diameter of tens and hundreds of
meters
In simple words, a tornado is a huge
whirlwind that washes away and destroys
everything in its path.

TORNADO STAGES
A tornado has stages that determine the danger of the tornado
itself.
1.Formation: The vortex begins as a swirling air column in the atmosphere, gradually
growing in size.
2.Development: The vortex intensifies, forming a distinct rotating structure.
3.Mature: At peak intensity, the tornado reaches its maximum strength and size,
capable of causing damage to buildings and infrastructure.
4.Shrinkage: The vortex starts losing energy and size, gradually weakening
5.Decay: The tornado dissipates, its strength decreases, and it eventually disappears.
