Tornado - research

Soooo, the tornado business, probably my favourite one.
I find it quite difficult trying to explain how it happens or what it is, even though I know so a lot of dictionary definitions were involved here :')
So, a tornado is a violently rotating column of air... for it to be classed as a tornado it's got to be in contact with both the surface of the earth, and a cloud base. 
Tornadoes come in many shapes and sizes, mostly come in a form of a visibly condensation funnel, the narrow end touches the earth and is usually surrounded by a cloud of debris and dust. It's nearly transparent, unless a cloud forms within the funnel, when it starts to pick up the dust and the debris it changes colour, which means it will match the colour of the ground.
Most tornadoes get up to 110 miles per hour and are about 76m across, and travel a few miles before dissipating.
The more extreme cases get up and above 300mph and stretch for more than two miles, and can stay on the ground for more than 100km.
Tornado winds are the fastest winds on Earth.
So I've read there are a few scales for rating the tornadoes.
The fujita scale for example, rates them by damage caused.
An F0 or EF0 tornado, the weakest category can damage trees etc but not structures.
An F5 or EF5 are the strongest category, it can deform large skyscrapers and rip buildings off their foundations.
Or a TORRO scale which ranges from a T0 (weak) to T11 (most powerful tornadoes).
It is possible that a single storm will produce more than one tornado.
Multiple tornadoes produced by the same storm are referred to a tornado family.
I was reading some interesting facts about tornadoes and I came across one that said that tornadoes can hop  along it's path, destroy one house, and leave the one next to it intact.
In 1928 a tornado lifted an 83ton train, and casually tossed it 80 feet from the tracks :')
Aaaaand I think that's about everything I wanted to mention about tornadoes C:
