The scale does not rate tornadoes on wind speed but on damage. The wind speeds for the categories (F0, F1 etc) are estimates for each damage level.
The wind estimates for F5 damage start at 261 mph. However, this estimates is believed to be too high. On the new scale, the wind estimates for EF5 start at 201 mph.
There is no set upper limit for an EF5 tornado. Any tornado with estimated winds in excess of 200 mph is considered an EF5.
The minimum wind speed for a storm to be considered a hurricane is 74 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.
An EF3 tornado has estimated winds of 136-165 mph.
The speed and direction of a tornado can be determined using Doppler radar by measuring how far the tornado moves between sweeps and in what direction.
It is useful to know the wind speed of a tornado because it provides an understanding of tornado intensity and dynamics. It is important to know the forwards peed of a tornado because that is needed to know when a tornado might reach a location in its path.
One the original Fujita scale F3 winds were estimated to start at 158 mph (254 km/h). However, it was more recently discovered that this estimate was to high. It was adjusted to 135 mph for an EF3 tornado.
There is no set upper limit for an EF5 tornado. Any tornado with estimated winds in excess of 200 mph is considered an EF5.
The minimum wind speed for a storm to be considered a hurricane is 74 mph.
The estimated wind speed of an EF0 tornado is 65-85 mph.
In rare cases wind speeds in a tornado can exceed 300 mph (480 km/h).
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.
RM 125 will be at the minimum 30 hp, top speed can be changed with the gearing, 90 mph with in reach, no problem. RIPP
By the standards of the Enhanced Fujita scale the minimum wind speed for an EF0 tornado is 65 mph. However, simply having a wind at or above this intensity is not enough for there to be a tornado. A tornado is a violently rotating vortex of wind, not just a gust above a certain strength.
The wind speed in the eye of a tornado is typically calm or very light, often less than 15 mph. This calm area is surrounded by the intense winds of the tornado's eyewall, which can reach speeds of over 200 mph.
I believe you are asking how fast tornadoes can travel. This varies. The average tornado moves at 35 miles per hour. Tornadoes may be stationary or may, in very rare cases, move at over 70 mph.
First it is nearly impossible to determine exactly where a tornado will hit or how strong it will be in a given location. Also, direct measurement of tornado winds is rare, so it is not known exactly how fast the winds in a tornado are, especially at and near ground level, most often it it estimated from damage.
