  3. Eastern Region Breakdown

  4. Central Weather Service Units

  5. Eastern Region Breakdown • 23 Weather Forecast Offices • 4 Central Weather Service Units • 133 TAFs four times daily • 11 Airports are 30 hour TAFs • Site Specific Amendment Criteria at • BWI, CLT, DCI, EKN, and IAD

  6. Eastern Region Breakdown • Airport Weather Warnings issued at 7 locations • ALY, BOS, BUF, CAE, ILM, MYR, PVD • Criteria varies from airport to airport: • Surface wind gusts >40 knots • Onset of freezing rain • Cloud to ground lightning within 5 miles of the airport • Thunderstorms with >½ inch hail • Onset of heavy snow

  7. Regional Aviation Duties • Liaison between NWS Headquarters and Weather Forecast Offices • Liaison between NWS Headquarters and Central Weather Service Units • Review feedback between WFOs and Aviation community • Collaborate with FAA, other NWS Regional Headquarters, and Aviation Weather Center • Formulate Policy • Quality Control • Coordinate Sub-Regional Aviation Workshops • Facilitate establishment of new TAFs and Airport Weather Warnings • Improve Aviation Verification Numbers

  8. CWSU Improvements • AWIPS Remote Display (ARD) • AvnFPS TAF monitoring program • Chat software • Web recording software • Conference calls with WFOs • Work TAFs

  9. Collaboration = Consistency • Daily conference calls between CWSU New York, WFOs New York City and Philadelphia. • Preliminary TAFs generated and collaborated for Dulles and Boston between CWSUs and WFOs. • CWSU New York and Atlanta daily conference calls with Delta Meteorologists

  10. CWSU ZDC – WFO Sterling

  11. Verification • NWS Goals FY 2009 • Probability of Detection (POD) 0.64 • False Alarm Rate (FAR) 0.36 • Eastern Region FY 2008 • POD 0.65 • FAR 0.33

  12. Albany Aviation On Demand • Near teal time feedback

  13. Albany Aviation Verification • Creates historical database • Six hour verification • Conduct research on specific events • Daily backup

  14. Verification

  15. Future New York City 2040?

  16. Ceiling Grids Click Here Experimental Digital Services

  17. Digital Aviation Forecasts

  18. Experimental Digital Services Visibility Grids

  19. Weather Impacted Traffic Index(WITI) • CCFP • TAF • Metars • Near real time verification of aviation forecast and impacts

  20. NAS Weather Index (WITI) vs.Combined WITI-FAand Delta (“forecast goodness”) 30-day period ending 11/12/2008 NWX = 100 is a “normally-impacted ” day Positive delta = Over-forecast of traffic impact Negative delta = Under-forecast of traffic impact Delta > +/-50 may indicate a forecast “issue” November 12, 2008 21

  21. OEP Airports Analysis Under-forecast at BOS (actual ceilings, 600-700 Ft, lower than forecast ceilings, 1300-1500 Ft) – however, no impact on operations due to low traffic demand on a Sunday
