Tо begin , a tornado is a vortex of air similar to a funnel.
A tornado is an extreme weather in our world. Of course , many people died of that.
I will tell you about a case in Bangladesh in 1989 (26 April) . The number of dead people is unknown, but in general there are about 1300. (12,000 people were injured) . This death numbers means that this is the deadliest tornado in the history of the world.
(Before the tornado, the area had been in drought for six months. It is a factor of the main reason of this tornado.)
The maximum wind was 350 kilometers per hour.
The damage was one and a half million dollars.
