What shape do tornado producing storms take on the radar screen?

When looking at storm relative velocity, the signature of a tornado, or at least the mesocyclone that produces it will show up as a bright green area next to a bright red area in a relatively small part of the image. This means that strong winds blowing toward the radar are right next to strong winds blowing away from it, indicating a strong rotation.
On a reflectivity image there will often be a hook shape on the radar image, showing where the mesocyclone is pulling the rain around.
See the link below for an example.
Note that these are not what images of the tornado itself looks like, but rather the mesocyclone that produces the tornado. Also note that not all tornadoes have such features on radar, and not all such features correspond to tornadoes.

What is the purpose of radar during a tornado?
Doppler radar is able to measure wind speed within a storm. If the radar detects a small portion of a storm with strong winds traveling in opposite direction, it means there is intense rotation which may be a precursor to the tornado or even the tornado itself. This can allow us to see a tornado ahead of time and warn people so they can get to safety. Some mobile doppler radar can yield high resolution data from within the tornado itself, allowing us to learn more about its internal dynamics and how tornadoes work.
Can or cannot a radar track down a tornado?
Doppler radar can, but with some limits. Doppler radar can detect rotation of a tornado, as well as the larger rotation that may produce one, but it cannot tell if the rotation reaches the ground. Additionally, radar may fail to detect weak tornadoes and tornadoes that are very far away.
How is wind speed determined in a tornado?
Wind speed is usually estimated based on the severity of damage that the tornado causes. In some cases it is measured by Doppler radar or, rarely, with an anemometer inside the tornado.
What instrument determines the presence of a tornado?
Tornadoes can be detected by Doppler radar, but eyewitness reports are important, too.
What device do the use to detect a tornado?
Today, we track tornadoes using a combination of eyewitness reports and Doppler radar.
What is the special type of radar used to predict when a tornado might touch down?
Doppler radar is used to track potentially tornadic storms.
What are the cloud patterns for a tornado on a radar screen?
Radar does not scan for cloud patterns. In the case of finding a tornado it looks at wind speed. If a winds are moving very fast towards the radar and winds moving fast awaay from it in a small area, it means strong rotation and a possible tornado.
What is an advisory in a tornado?
they are no advisory in tornadoes only a warning or watch a warning means that Doppler radar and storm watchers indicated tornado formation and a watch is Doppler radar indicated weather conditions producing severe thunderstorms that can produce tornadoes
Is there technology that can help predict tornadoes?
Yes. Tornado watches are issued based partly on computerized weather models and tornadic storms are tracked using Doppler radar.
Where are the storm chasers at right now?
they go to where there are big open fields like South Dakota, Texas, Kansas, etc.
What is better to find a tornado with. radar or aneroid barometer?
A a radar is better: it can detect a tornado at a distance. A barometer would be of no use unless the tornado came dangerously close.
What is an annoucement that a tornado has been spotted?
If a tornado is spotted or is detected by radar, then a tornado warning will be issued.
What kind of radar is used to record tornado data?
Usually Doppler radar is used.
What radar can predict when a tornado might touch down?
Doppler radar can be used to make such predictions.
How are storms detected on Doppler radars?
If you could build a form of RADAR that is able to bounce signals off the raindrops inside a storm cloud then you could detect storms by RADAR
Is Doppler radar used for finding hurricanes?
Yes, Doppler Radar can be used to find all storms!
A tornado warning means that a tornado has been spotted on ground or on radar?
Much of the time, yes. However if radar detects strong enough rotation in a storm, indicating a tornado is likely to form soon, that may also prompt a tornado warning.
