TORNADOS

A tornado is a powerful columnof winds al time in spiral

around a center of low pressure atmospheric. It looks

like a large black funnel hanging down from a storm

cloud, the narrow end will move over the earth, whipping

back and forth like a tail.In this article you can know the

most stronger tornado in USA history and a little bit that

as create.I can infer that the moststronger tornado is the

Reno tornado in may 31, 2013 the Reno tornado have

the first place to the world record 302 mph winds

recorded in the Moore.

How do tornado form?

1.- Air Rotates because of wind shear.

2.-Faster spin makes a funnel cloud.

3.-The funnel rotates and touches down.

Tornados always is a factor in USA one of the problems

is that in U.S territory only the 30% of territoy have

mountains but the other 70% don’t have mountains as I

said the most stronger tornado is Reno in Oklahoma,

according to comments and information made by

tornado researcher Rick Smith at a press conference the

past june 1, 2013, the mobile radar was positioned on

top of an overpass, and recorded winds close to the

surface of up to 295 mph in satellite suction vortices that

orbited the large, main vortex, have a 2.5 miles in

diameter.
