The average person and weather enthusiast can follow along on social media with reports in real-time as volatile weather unfolds -- and terms like "radar-confirmed tornado" are often thrown out by ...
Classic-style hook echo of the F5 1999 Bridge Creek-Moore tornado.. A hook echo is a pendant or hook-shaped weather radar signature as part of some supercell thunderstorms.It is found in the lower portions of a storm as air and precipitation flow into a mesocyclone, resulting in a curved feature of reflectivity.
A Doppler on Wheels radar loop of a hook echo and associated mesocyclone in Goshen County, Wyoming on June 5, 2009.Strong mesocyclones show up as adjacent areas of yellow and blue (on other radars, bright red and bright green), and usually indicate an imminent or occurring tornado.
A tornadic debris signature (TDS), often colloquially referred to as a debris ball, [1] is an area of high reflectivity on weather radar caused by debris lofting into the air, usually associated with a tornado. [1] [2] A TDS may also be indicated by dual-polarization radar products, designated as a polarimetric tornado debris signature (PTDS).
A tornado watch means weather conditions could spawn tornadoes within the watch area. People should stay aware of weather conditions and be prepared to act if watchers spot a tornado.

Strong mesocyclone on a thunderstorm near Tuscaloosa, Alabama, that was analyzed as fitting the characteristics of a TVS.It was associated with a tornado.. A tornadic vortex signature, abbreviated TVS, is a Pulse-Doppler radar weather radar detected rotation algorithm that indicates the likely presence of a strong mesocyclone that is in some stage of tornadogenesis. [1]
The tornado alert was finally eliminated outright because it was made largely obsolete by the advent of Doppler weather radar, which can detect rotational funnel cloud formations earlier than is typically possible by trained spotters and members of the public. With fewer false-positives, radar also helped reduce public confusion over storm ...
