Doppler radar primarily. Velocity radar imagery estimates how fast the winds are moving either to or from the radar site. Meteorologists can estimate using mathematic formulas what the surface winds are. Tornadic signatures show up as two opposing colors next to each other.
After the tornado has been confirmed, the Naitonal Weather Services sends a research team to the area to examine structural damage and then get a better idea along with any recorded weather measurements of how strong the tornado was.

How do scientist know how fast a tornado is going?
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.
What keeps wind rotating inside a tornado?
The rotation in a tornado is driven by the wind shear, which is the change in wind speed and direction with height. This wind shear creates a horizontal rotation that is then tilted vertically by updrafts in the storm, leading to the spinning motion of the tornado.
What type of motion does a tornado causes a tornado?
It's caused by wind going in circular motion.
What happens when a tornado goes over a hill?
When a tornado goes over a hill, its intensity can fluctuate. The wind speeds may increase on the uphill side and decrease on the downhill side due to the change in terrain elevation. Additionally, the tornado may change direction or path as it interacts with the hilly terrain.
Why does the size of a tornado not determine the damage of a tornado?
The damage severity in a tornado is determined primarily by wind speed. For example, a tornado with peak winds of 100 mph, even if it is very large, is not going to obliterate well built houses, thought it will cause severe roof damage. By contrast, even a relatively small tornado with peak winds of 250 mph can completely destroy just about any structure.
What instrument did the ancient Chinese invent that helped sailors figure out where they were going?
compass
What instrument did the ancient Chinese invent that helped sailors figure out were they were going?
compass
How is pedigree helpful to scientists?
A pedigree is helpful to scientists because then they can figure out what trait and/or sex-linked disorder is being passed on and if it is going away.

When was Gradually Going Tornado created?
Gradually Going Tornado was created in 1980-02.
Is there going to be a tornado tomarro in round lake beach?
Yes there is going to be a tornado in round lake beach.
If a tornado is dissipating which direction will the next tornado come from?
THAT Depends on where the Storm that produced that Tornado is going
Where do scientists go to study tornadoes?
meteorologists study tornadoes, they learn more about them by chasing them. it's a dangerous job since you never know with path a tornado is going to take.
Is there going to bea tornado?
It is inevitable that there will be a tornado somewhere, probably fairly soon.
Which instrument do you use to see stars and planets?
A spectrometer is used to determine the composition of stars, and how fast they are going relative to Earth.
When is Arizona going to have or next tornado?
It is impossible to predict when the next tornado will happen anywhere.
How can a scientist predict when a tornado is going to happen?
In the first stage of tornado prediction scientists look for general weather conditions. The conditions include wind shear and systems that can form strong thunderstorms such as a cold front, dry line, or low pressure system.If such general conditions are in place a tornado watchis issued.The second stage scientists look for conditions that may soon produce a tornado, or if a tornado is forming. These include using Doppler radar to look for strong rotation in thunderstorms or possibly even the signature of an actual tornado. Storm spotter are also sent out to report strong rotation, funnel clouds, and tornadoes. If strong enough rotation is detected or if an actual tornado or funnel cloud is spotted or detected a tornado warning is issued.
