Doppler: Radar With A Life-Saving Purpose The chief purpose of Doppler radar is to improve tornado warnings. The radars are sensitive enough to detect the actual funnel cloud itself; more often than not, NEXRAD is searching for the so-called “mesocyclone” — the intense low-pressure ...
Doppler radar is widely credited with major advances in weather forecasting. Still, it seems like inaccuracies in forecasting may be able to be attributed to this as well. As the article says, the radar can tell the distance and velocity of cloud movement, but many times a radar shows activi...
Isn't Doppler radar imaging technology also used on a larger scale to predict the weather, "see" oncoming tornadoes, etc.? Or is that something completely different? The Health Board, in your inbox Our latest articles, guides, and more, delivered daily. ...
What is pulse Doppler radar?Waves:A wave is a disturbance that propagates from one point to another and possesses certain quantities like frequency, speed and wavelength. Waves are broadly divided into two groups of mechanical waves that require a medium to travel from one point to another, ...
Radar is a sensor system that not only detects but also recognizes objects from a significant distance. The radar operation includes the emission of electromagnetic energy in the form of a beam and detecting the wave getting reflected after it strikes the atmosphere....
The other way we detect tornadoes is with radar imagery. Patterns in radar, like the tornadic vortex signature (TVS), are a good indication that a tornado has developed. Computer programs, called algorithms, analyze Doppler radar data and display it in ways that make it easier for forecasters...

On stormy nights, the meteorologist will interrupt regular programming. He will always say that Doppler radar indicated rotation in a certain area. He is quick to point out that just because Doppler radar picked up on rotation, this doesn't mean an actual tornado is on the ground. It does ...
The term "bow echo" was introduced by Fujita in 1978 to describe a radar pattern that has a "distinct shape, like that of a bow or crescent." Fujita found that his bow echoes were often associated with severe surface wind swaths caused by downbursts. He also conjectured that bow echoes...
