Detecting Tornadoes

May 13, 2010 from Climate Central

While most people would do anything to stay away from tornadoes, some scientists seek out these storms. Scientists are assisted by a nationwide network of Doppler radars, which are powerful tools for monitoring severe thunderstorms and tornadoes. These radars allow scientists to visualize the winds within the storm, and by using those winds they provide forecasters with advance warning. Smaller, portable Doppler radars are currently being used in a field project called Vortex 2. During the 2009 and 2010 tornado seasons, Vortex 2 has been tasked with seeking out tornadoes in "tornado alley". Vortex 2 scientists intend to collect the most complete three-dimensional pictures of tornadoes that have ever been generated. The results of this project may result in a better understanding of how tornadoes develop, which could lead to better short-term tornado forecasts and warnings. Additional study is needed to determine if a warming climate may lead to more tornadoes, or causes a change in where and when tornadoes appear.

Tornado

A tornado is a violently rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. They are often referred to as twisters or cyclones, although the word cyclone is used in meteorology, ... Explore this topic

A Doppler radar is a specialized radar that makes use of the Doppler effect to produce velocity data about objects at a distance. It does this by beaming a microwave signal towards a desired target and listening for its reflection, then analyzing how the frequency of the retur... Explore this topic
