Natural Disasters: Tornadoes











Tornadoes are columns of rotating air that extend from the ground to the clouds.

Winds can reach upto 300mph and may not be visible until debris is pick up.
Damage paths can be one mile wide and 50 miles long.
Tornadoes on water are called waterspouts. the average speed of a tornado is 30mph but can be stationary or even reach upto 70mph. Tornados can vary in width from very thin and barely able to see upto evidence showing tornados being 2.5miles wide!
There can be multiple tornadoes at the same place which can merge into a more powerful tornado.

Powerful storm clouds that form tornadoes are called supercells.
