Question:
What devices do people/scientists use to know if a tornado/twister is coming?


Replies:
Here in Oklahoma, we depend on radar for a warning. A kind of radar, very much like what police use to catch speeding drivers, shows us when the storm starts twisting to form a tornado.

When there are storms around we watch the television or even the Internet. We also have sirens that shriek whenever a tornado is near. They also broadcast warnings over all our radio stations.

Hope this helps. Bob Avakian Tulsa, OK


Hi Rosie,

Meteorologists are people who study weather and tornadoes. Meteorologists use radar and computers to predict when and where a tornado will occur. However, the methods are not always accurate and cannot predict all tornadoes.

I hope this helps. Thanks Jeff Grell


There are of course, visual sightings, but for a predictive model a tool called Doppler Radar is used to detect the anticlockwise motion of cloud cover. That is what the weather reports and warnings to find a safe place come from.
