The large majority of the tornadoes in the northern hemisphere spin counterclockwise (cyclonically), but about 1 in 100 tornadoes spin clockwise. Actually, it has little to do with being in the northern hemisphere, as tornadoes do not last long enough for the effects of Coriolis to impact it.
A tornado is defined as a violently rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of 250 mph or more. Damage paths can be in excess of one mile wide and 50 miles long.Once a tornado in Broken Bow, Oklahoma, carried a motel sign 30 miles and dropped it in Arkansas!n area of rotation, 2-6 miles wide, now extends through much of the storm. Most strong and violent tornadoes form within this area of strong rotation. A lower cloud base in the center of the photograph identifies an area of rotation known as a rotating wall cloud. This area is often nearly rain-free.
