Winds in a tornado may range from 65 mph to over 300 mph (the exact upper limit is not known).
Most tornadoes have winds less than 110 mph (EF0 and EF1), but the ones that cause the most damage (EF3-EF5) have winds over 135 mph.
"TORNADO"
Estimated winds in a tornado can range from speeds as low as 65 mph to over 300 mph.
It varies widley. A rapidly developing tornado may only been in the dust whirl statge for a few seconds, while others may linger in this phase for several minutes. Some tornadoes never grow beyond this stage.
The "fire tornado" forms from the fire; it doesn't really matter how the fire starts. Also, a "fire tornado" is more properly called a fire whirl as it technically isn't a tornado.
Winds in a tornado can get up to 300 mph.
i think the middle of the tornado is completely still.
Whirl velocity of a turbine is determined by how fast the turbine can turn when it is moving. This is a factor considered with airplane manufacturing. Whirl velocity is the number of times in a second that a turbine can rotate, moving at a given speed.
The Tornado's max speed is 1,490 mph
A tornado IS wind- very fast winds spinning in a circle.
Optical illusion.
All tornado contain rapidly rotating winds. Most tornadoes contain a condensation funnel and a whirl of dust and/or debris.
Not really. A tornado is defined as a violent rotating column of air, but when a strong tornado hits a populated areas, it picks up pieces of buildings, adding high speed debris to the vortex. Even a weak tornado creates a whirl of dust.
