Leveraging Total Lightning and Convective Initiation Data for Impact-Based Decision Support Services

This presentation explores the integration of Total Lightning and Convective Initiation (CI) data in decision support services at WFO Huntsville, AL. With an over 11-year collaboration with SPoRT and a focus on severe weather detection, WFO Huntsville has effectively leveraged unique datasets to improve on-site Impact-Based Decision Support Services (IDSS). Key events, such as the outdoor arts festival Panoply and the Rock the South concert, highlight the application of these data systems in ensuring safety during severe weather.

  1. Leveraging Total Lightning and Convective Initiation Data for Impact-Based Decision Support Services Brian Carcione WFO Huntsville, AL

  2. Background – Total Lightning • WFO HUN has a long history (~11 yrs) with SPoRT and Total Lightning from North Alabama Lightning Mapping Array • Convective Initiation from UAHuntsville off and on for ~8 years • Traditionally used for severe weather detection Courtesy Dr. Steve Goodman Huntsville

  3. Background – Decision Support • HUN has a long history here too, but it has ramped up markedly in the last 2-3 years • 27 April 2011 event, recovery, anniversaries • Work with EMA for protection of life & property

  4. On-Site IDSS with Unique Data • AWIPS importance has changed due to IDSS • SPoRT & UAH have been great about presenting their data in a (mostly) easily-accessible, web-friendly format GOES-R CI – SPoRT Web Page NALMA – Google Earth Browser Plugin

  5. Panoply • Outdoor arts festival in downtown Huntsville, AL, late April • Draws ~300,000 people over 2 ½ days • Strong weather sensitivity • History of bad weather • One day shut down for tornadoes in 2010; completely shut down in 2011 (4/27 effects)

  6. Panoply 2013 • First night – scattered showers/storms threatened • NALMA data leveraged at WFO and on-site to determine threats • Organizers accelerated closing fireworks show, but last few fireworks still coincided with lightning

  7. Panoply 2013 • New challenges Saturday (tornado watch, scattered storms) but no direct impacts aside from rain • Extended anvils created a “long flash” risk in the evening • DSS met. at WFO conveyed to on-site staff

  8. AWIPS II LMA Source Density 2328 UTC 27 April Panoply Site (Downtown Huntsville) 10 5 20 Single flash perspective from “XLMA” software

  9. Rock the South Concert • Outdoor concert in Cullman, AL • Originally designed to support victims of April 27 outbreak; now set in June (active convective season) • ~40,000 attendees over 2 days • Heightened sensitivity after Indiana State Fair

  10. Rock the South Concert • CI permitted anticipation • Important to realize CI goals (35 dBZ, NOT CGs) • Looked for any total lightning signals, not just the jump • Fortunately, activity was very isolated

  11. The Next Step? • AWIPS II “Thin Client” could be a game-changer for DSS • HUN testing on a “low-grade” level inside the WFO • GOES-R CI easily available (Grib2), Total Lightning not quite yet • Hasn’t been a top priority yet due to prolonged OT&E, but will increase in importance with increased IDSS

  12. Questions? • Brian.Carcione@noaa.gov • Web Sites: • NALMA Google Earth Plugin (also for DCLMA) • http://weather.msfc.nasa.gov/sport/lma/nalmaSourceDensity.html • GOES-R CI: • UAH: http://nsstc.uah.edu/SATCAST/ • SPoRT: http://weather.msfc.nasa.gov/cgi-bin/sportPublishData.pl?dataset=goesrcieast
