There is no such thing as a ‘mini-tornado’. … A site investigation carried out by a member of TORRO (TORnado and storm Research Organisation) concluded from a damage survey that a tornado with an intensity of T2 moved through (winds between 73-92mph) – so it could be classed as EF1 (winds 86-110mph).

What state has never had a tornado?

Has there ever been an F6 tornado?
In reality, there is no such thing as an F6 tornado. When Dr. Fujita developed the F scale, he created a scale that ranges from F0 to F12, with estimated F12 winds up to mach 1 (the speed of sound).
What happens if two tornadoes collide?
When two tornadoes meet, they merge into a single tornado. It is a rare event. When it does occur, it usually involves a satellite tornado being absorbed by a parent tornado, or a merger of two successive members of a tornado family.
Can you run through a dust devil?

Could a tornado lift a tank?
If the tornado winds can get a purchase on the tank and flip it, the tank would be rendered unusable without depot maintenance. There are cases where flipped tanks were righted and then driven to the maintenance depot. The tank crew would survive unless the tank was tumbled.

Can an f1 tornado pick up a person?
Yes, a tornado can lift a person but not that high. Consider this: a human body is roughly 300 times denser than the air. As it is being lifted, it suffers the spinning moment of the tornado; mostly counter-clockwise in the northern hemisphere but, sometimes clockwise (anticyclonic tornado).
