Records of tornado occurrences are fragmentary for many areas, making estimates of global tornado frequency difficult. tornado, a small-diameter column of violently rotating air developed within a convective cloud and in contact with the ground. The most powerful twisters have wind speeds of more than 300 miles (483 kilometers) per hour, which can rip buildings off their foundations. Large temperature differences are associated with early winter cold fronts that move rapidly across the country from the north and west, at times spawning widespread outbreaks of small tornadoes. A typical lifetime for strong tornadoes is about eight minutes, while violent ones last about 25 minutes. For example, the passage of a very strong frontal boundary across the United Kingdom on November 23, 1981, produced 105 documented tornadoes. The Fujita scale, or F-scale, measures the intensity of a tornado based on the damage it causes.
