Tornado debris signature - Wikipedia
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.
Severe Weather Radar Terms And What They Mean | Weather.com
Mar 20, 2024 · R adar displays several visual cues to meteorologists when tracking severe weather and tornadoes. "Debris ball," "hook echo" and "bow echo" are just some of the terms you might have heard...
NWS Doppler Radar Dual Pol - Tornado Debris - National Weather Service
This is dual pol's depiction of a "debris ball" at the location of the tornado, i.e., various debris caught within and rotating around the tornado, and lifted up into the parent thunderstorm. This CC signature would be less evident for weaker tornadoes and for storms distant from the radar.
Understanding advanced tornadic radar signatures
Mar 28, 2017 · Seeing a "debris ball" on radar from a tornado if fairly easy, but there are more subtle signs on radar that can tell meteorologists if there is a tornado.

What is a tornado debris signature, or ‘TDS’? How is it used to …
Nov 8, 2018 · National Weather Service damage survey reports show damage consistent with an EF-1 Tornado in Jackson County. How are tornado debris signatures (TDS) used to detect tornadoes?
Dual-Pol Applications - National Weather Service
Tornadic Debris Detection Thanks to our new capability to be able to detect radar echoes with greatly-varying particle size and shape, we will now at times be able to confirm the presence of a tornado when enough debris are lofted into the air to be detected by the radar.
The Online Tornado FAQ (by Roger Edwards, SPC) - NOAA/NWS …
What is the tornado (or tornadic) debris signature? Capabilities retrofitted to our national Doppler radar network since 2010 allow warning forecasters to detect debris plumes lofted into the air by some (not all!) tornadoes. Background: Radar beams now transmit with both horizontal and vertical waves. This is called "dual polarization".
Tornado Debris Project - University of Oklahoma
What is the purpose of the Tornado Debris Project? The Tornado Debris Project, administered through the School of Meteorology at the University of Oklahoma, aims to study debris transported long distances by tornadic thunderstorms.
Tornado: Definition, Facts, Formation, Damage
Dec 9, 2024 · A tornado is a violently rotating column of air that extends from a thunderstorm to the ground. Tornadoes form through an interaction of atmospheric conditions. Tornado damage results from winds and flying debris. Tornado intensity is measured on a scale. Tornadoes carve a path across the landscape.
