Tornado Damage Levels: F0 - F5

[ad_1]

In the US, tornadoes were classified according to the Fujita scale from a F0 to an F5. There was also room for an F6, yet we've never had one that destructive.

In 2007 the US converted over to a slightly different scale, the Enhanced Fujita scale. It's pretty similar. The scale was revised to reflect better examinations of tornado damage surveys, so as to align wind speeds more closely with associated storm damage. It allowed for better standardizing of what was previously subjective and ambiguous. It also adds more types of structures and vegetation, expands degrees of damage, and better accounts for variables such as differences in construction quality. The old scale lists an F5 tornado as wind speeds of 261--318 mph (420--512 km/h), while the new scale lists an EF5 as a tornado with winds above 200 mph (322 km/h), found to be sufficient to cause the damage previously ascribed to the F5 range of wind speeds.

In any case, I made this video about the original Fujita Scale. Just remember that tornados damage is what is used to ESTIMATE wind speed. It's the same with the EF scale.

Thanks to the storm chasers in Oklahoma we went out with!
