Tornados are one of the most frightening weather phenomena2 on our planet. Not only are they unique in how they form, but also in how they are measured . A tornado1’s intensity3 is defined by the Enhanced Fujita Scale. On this scale, the intensity of the tornado correlates to the damage it produces . Damage on the scale is rated from zero to five, zero being the least destructive and five the most. EF 0 storms are the most common. Their winds are estimated to be from 65 to 85 mph and cause very little damage. At the top of the scale, EF 5 tornadoes4 are the least common and the most destructive with winds over 200 mph.
