Tornado

A tornado is a dangerous storm with a rotating column of air that extend from a thunderstorm cloud in the sky to the earth's surface.Tornadoes form when warm moist air from the gulf of mexico mix with cool dry air from Canada.When these two subjects mix they make instability in the air.This makes warm and humid parts in the lower part of the atmosphere and possibly a cooler dryer condition in the upper part of the atmosphere.Tornadoes are the most violent atmospheric storms.They usually range for a couple of seconds but the world's longest tornado lasted for 3 hours and a half in the USA.Some very violent tornadoes can cause terrible damage they can damage many things like cars,trees,houses and lots of other stuff.
