Seasoned storm trackers provide critical field data that can't be gleaned from high-powered Doppler radar, veteran meteorologists say.
Some of them were on instrumented vehicles that included mobile Doppler Radar that also contributed to the excellent warnings issued for that tornado.
Anthony Pallot said the Doppler radar, near the German lookout tower at La Moye, could detect the intensity, location and how rain was moving.
The fires (some awesome video here) created a plume of smoke that stretched for 30 miles, just skirting downtown Houston and visible on doppler radar.
Doppler radar allowed forecasters to see more than just precipitation.
Other sites show up-to-the-nanosecond forecasts and Doppler radar satellite images.
Knowing that the atmosphere could produce a strong tornado, they immediately issued the tornado warning as soon as the Doppler radar started to show low-level rotation within the storm.
In the late 1980s we deployed the new Doppler radar, the WSD-88, which can actually track the movement of air within a storm (and therefore pinpoint a tornado vortex).
While tools such as Doppler Radar detect winds within severe storms that could indicate a tornado may be imminent, many of these rotating storms do not go on to produce tornadoes.
The deployment of the Doppler radar system in the early 1990s by the National Oceanic and Atmospheric Administration extended tornado warning lead times from five minutes to their now-annual average of 12 to 14 minutes.
The program, known as "Biometrics-at-a-distance, " would essentially combine two pre-existing Pentagon projects: the Radar Scope, a device that can see through walls, and 2009's LifeReader, a system that uses Doppler radar to detect heartbeats.
Doppler weather radar was part of a wider modernization of forecast offices nationwide lasting nearly a decade.
After the deployment of Doppler weather radar, lead times for tornadoes were nearly doubled, from less than five minutes to around 10 to 13 minutes.
In the early 1990s, Doppler Weather Radar, or as it was more commonly known, Next Generation Weather Radar, was deployed at local National Weather Service forecast offices nationwide.
Although tornado forecasting has remarkably improved over the last two decades with advanced forecasting techniques, weather satellites, numerical forecast models and Doppler weather radar, there is much about tornado forecasting that still remains a mystery.
The car can park itself, it will automatically detect and avoid other vehicles thanks to radar and doppler sensors.
