Aviation Weather Center Update Friends and Partners of Aviation Weather Jack May, Director Aviation Weather Center All Hands October 13, 2004
Rapid Fire Update on Many Fronts • Graphical Forecast for Aviation • Timeline of AWRP products • Verification of IFR accuracy. • Report Flight Plan Freezing Level for ADDS • GFA on ADDS • AWC Web Based Pireps • NWS Polygon Warnings Investigation
AWRP Products Timeline Estimates for FY2005 As of 8/9/04
AWRP Products Timeline Estimates for FY2006 As of 8/9/04
Accuracy of Short Term Forecasts • Improve Accuracy of short term forecasts, especially of C&V to avoid over forecasting VNR and over-dissemination of warnings.
GFA on ADDS • Operational ADDS • NWS Budget Item for FY05 to prepare for FY06 supplemental products. • Presently under continuing resolution. No new spending.
Latitude/Longitude points are found at the bottom of all warnings today. NWS Polygon Warnings
Polygon Advantages Polygon Eliminates Area False Alarmed
One WFO Study (2004) • Over two convective seasons, issued 46 tornado warnings that covered: • 38,280 square miles • Included 595 individual towns • Utilizing the polygon approach, the polygons covered: • 10,374 square miles • Included 169 individual towns • If the polygon approach were in place: • Would have reduced our total warning area by 22,490 square miles • Would have unnecessarily warned 426 fewer towns • That's a reduction of 72%!
Polygon Advantages • Shows specifically where the threat is • More accurately shows warning area on systems displaying warnings graphically • Reduction of risk area (Aviation as well as public) • Better graphical description capabilities • Wider local distribution via cell phones, PDAs, etc. • Increase NWS role in the confirmation part of the warning process • Private sector requirement for polygons • Better warning quality
