A tornado is a rapidly spinning tube of air that touches both the ground and a cloud above.
Tornadoes are sometimes called twisters.
Not all tornadoes are visible but their high wind speeds and rapid rotation often form a visible funnel of condensed water.
The Fujita Scale is a common way of measuring the strength of tornadoes. The scale ranges from F0 tornadoes that cause minimal damage through to F5 tornadoes which cause massive damage.
Most tornadoes have wind speeds less than 100 miles per hour (161 kilometres per hour).
Funnel clouds usually last less than 10 minutes before dissipating, and many only last several seconds. On rare occasion, cyclones last for over an hour, and many were recorded this way in the early 1900s.
A tornado may appear nearly transparent until dust and debris are picked up or a cloud forms within the funnel.
Tornadoes can accompany tropical storms and hurricanes once on land.
Twisters strike predominantly along Tornado Alley — a flat stretch of land from western Texas to North Dakota. This region is a hotspot for tornadoes because the dry polar air from Canada meets the warm moist tropical air from the Gulf of Mexico.
Tornadoes are most likely to occur between 3 and 9 pm, but can occur at any time.
The United States have an average of 800 tornadoes every year.
Each year, dozens of Americans die from tornadoes.
Usually, a tornado’s color matches the color of the ground.
Some tornadoes make a considerable amount of noise while others make very little. It depends on the objects a tornado might hit or carry. A tornado moving along an open plain may make very little noise.
Some people think the crop circles in the UK are the result of weak whirlwinds. About 60 of these small tornadoes are formed every year in Britain.
Tornadoes cause an average of 70 fatalities and 1,500 injuries in the U.S. each year.
The strongest tornadoes have rotating winds of more than 250 mph.
Tornadoes can be one mile wide and stay on the ground over 50 miles.
Tornadoes may appear nearly transparent until dust and debris are picked up or a cloud forms within the funnel.
The average forward speed is 30 mph but may vary from nearly stationary to 70 mph.
Waterspouts are tornadoes which form over warm water. They can move onshore and cause damage to coastal areas.
Every tornado has its own color, sound and shape.
You need to step on the pedal of a car pass 70 miles per hour to outrun the fastest tornadoes.
The chances that a tornado is a F5, the highest classification for a tornado on the F-scale, is less than 0.1%
Tornadoes have been reported in every state in the US and also in every season.
A Tornado can occur at any time, but most often between 3pm and 9pm.
