Operational Use of Polarimetric Tornadic Debris Signatures
This presentation will include examples of debris signatures from the NWS Atlanta, Birmingham, Huntsville and Nashville county warning areas. These events range from short-lived to long-track tornadoes, and provide a spectrum of information on how the debris signatures were used in operational forecasting. Topics covered are use of the debris signatures for real-time and post-event operations, the importance of separating low signal-to-noise and non-uniform beam filling artifacts from the debris signatures, and a discussion of differences in appearance of the signature in analysis software. A case where debris signature criteria were met, but no damage was observed, will also be shown. Final thoughts and lessons learned will be highlighted for future use of the signature in operations.
