Tornado strength can be classified on the Fujita scale of intensity which numbers from 0 to 5. F5 tornados are the most destructive known, with winds over 250 possible. F0 tornados are the weakest, though they can still produce significant damage.

Tornado was a shortlived weekly British comic published for 22 issues by IPC Magazines between March 1979http://www.2000adonline.com/?zone=prog&page=specials&choice=tornado01 and August 1979. After the cancellations of the Starlord and Action titles IPC launched Tornado as a way to use up stories already commissioned for the other titles. Like Action it was a mixed title featuring War, Detective, Horror and Science Fiction stories.
Tornado was a competitor on the UK TV series Robot Wars, noteworthy as the champion of the sixth series.
The Tornado is a fictional red biplane in the Sonic the Hedgehog series of video games. It made its first appearance in Sonic the Hedgehog 2 and has since featured in many other Sonic games. It is typically piloted by Miles "Tails" Prower, while Sonic or other characters walk on its wings.
