info of tornadoes

A tornado is a violently rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases , the base of a cumulus cloud.They are often referred to as twisters or cyclones , althought the word cyclone is used in meteorology ,in a wider sense ,to name any closed low pressure circulation .Most tornadoes have wind speeds less than 110 miles per hour (177 km/h), are about 250 feet (76 m) across and ,travel a few miles (several kilometers ) before dissipating .The most extreme tornadoes can attain wind speeds of more than 300 miles per hour (483km/h) ,stretch more than two miles (3.2 km) across , and stay on the ground for dozens of miles (more than 100 km)
