It varies widely. The weakest have winds of about 65 mph, while the strongest have winds over 300 mph.
Winds in a tornado can get up to 300 mph.
A tornado IS wind- very fast winds spinning in a circle.
Most damage in a tornado is caused by the extremely fast winds.
The Enhanced Fujita scale puts the beginning of tornado winds at 65 mph. Doppler radar has detected winds in a tornado of just over 300 mph.
How fast a tornado is moving refers to how fast the tornado itself travels from point A to point B. For example, a tornado moving towards at 30 mph and is a mile away will reach you in 2 minutes. The rotational winds of a tornado refers to how fast the tornado itself is spinning, which is generally faster than its forward speed.
It is impossible to know exactly how fast the winds were as we did not have the tools to measure a tornado's winds back then. But since the tornado was rated F5 (equivalent to EF5 on the new scale) winds were probably well over 200 mph.
Doppler radar measured winds at 301 mph +/- 20 in that tornado at a height about 100 feet above the ground. These are the fastest winds ever recorded on earth. However, it is possible that other tornadoes were stronger but did not get their winds measured
Winds inside a tornado can range from 65mph to over 300 mph. Most tornadoes have winds less than 110 mph. The ones that cause major damage are usually in the strongest 5% with estimated winds over 135 mph.
Winds in a tornado spiral inward and upward.
Doppler radar tracks the movement of the storm and can determine how fast it's going and, to a very limited degree, how fast its winds are. However, in nearly all cases the wind speeds reported in a tornado are estimated based on the severity of the damage that has been done.
The winds in a tornado can vary greatly and be any where between 65 and 300+ MPH. The majority of tornadoes have winds of 110 mph or less while the most damaging have estimated winds over 135 mph.
When surface winds slow down in a tornado due to ground friction, the tornado may weaken or dissipate altogether. This is because a tornado's strength is dependent on the fast rotation of air at the surface, so when this rotation slows down, the tornado's intensity is reduced.
