In 1971, Theodore Fujita developed a classification for tornadoes known as the F-scale. This system is based on how much damage is caused by the winds associated with tornadoes. However, a tornado's actual ground-level wind speed is pretty much unknown. Most tornadoes are F0 to F1. The rest are mainly F2 or F3. Only one percent are F4 or F5.
