  1. Delta Air Lines Meteorology

  2. Department Information • Begin in 1960 • 12 Meteorologist • 2-3 Meteorologist on-shift • every hour, every day • 1 Surface Forecaster • 1-2 Upper Air Forecaster • Weather data comes in from WSI and the NWS Delta Meteorology

  3. Primary Customers • Flight Control and OCC • Flight Operations • In-Flight • Stations • De-Icing Operators Delta Meteorology

  4. Upper Air Hazards Delta Meteorology

  5. Upper Air Turbulence Chart Delta Meteorology

  6. Upper Air Turbulence Chart Delta Meteorology

  7. Metro Alert Example SE1 031908-041500 ******* SOUTH CENTRAL REGION ****** OVR MS-GA-SC-NC..FM SJI-MCN-CAE-RDU.. 100NM WIDE LINE OF LGT-MDT TURBC AT FL340-390/TROP MOVG SE 10KTS. Delta Meteorology

  8. Current Text Distribution Meteorologist types forecast Main Frame Dispatcher Queue Flight’s Metro Briefing Message Flights Affected Delta Meteorology

  9. Upper Air Meteorologists Monitors: PIREPS – for icing and turbulence Volcano Activity Suggest: Smoothest Flight Levels Delta Meteorology

  10. Flight Planning Message Example ** NORTH ATLANTIC EBND FLT PLANNING MSG - 14 NOV 08 ** / 1. COLD TEMPS..ERN TRACKS-EUROPE (FL370-390)..SEE MAP / 2. RTES/FLS.. COASTAL NEW ENGLAND: SUGG AOB FL320..NBFL LOWER. OVR SERN CANADA: SUGG FL340-360..NBFL HIGHER. TRACKS/SRN RANDOMS (32-20W): SUGG FL310-340..NBFL HIGHER. OVR WRN EUR: MIN COST..NBFL HIGHER. SCANDINAVIA/ERN EUROPE/WRN RUSSIA: SUGG 270-340..NBFL HIGHER. / 3. ETPS.. YYT/YQX/YJT/YYR..USEABLE. KEF/TER..USEABLE. DUB/GLA..USEABLE. TRD/OSL..USEABLE. LIS..USEABLE. Delta Meteorology

  11. Surface Desk • Normal Operations: • 3 Shift Change Briefings with Stations • Dispatcher Briefings • Planning for the week/weekend • TAFs • Irregular Operations (IROPS): • Tropical Activity • Major Snowstorm Delta Meteorology

  12. TAF Cities LGA, JFK, EWR BOS SLC CVG PHL DELTA TAF CITIES DCA, IAD, BWI LAX ATL MCO Delta Meteorology

  13. DCA Runway 04/22: 4911 feet Runway 15/33: 5204 feet Runway 01/19: 6869 feet Our aircraft fleet generally prefers 5500ft. Leaves operation on Runway 01/19 Strong winds from the west or east cause crosswind issues. Delta Meteorology

  14. DCA Delta Meteorology

  15. Delta TAF Example • TERMINAL FORECAST • ATL DL 231405 AMD 02 VALID 231405-240400 UTC • FM231400 09010KT 2SM -RA FG OVC003 TEMPO 1SM -RA FG • FM232000 17010KT 2SM -RA FG OVC008 • FM232200 29010KT 5SM -RA OVC010 • FM240000 31012KT 7SM OVC015 • DISCUSSION – LOW CIGS WILL IMPROVE AFTER FRONT MOVES THRU AND WINDS BECOME FROM THE WEST. • Extra fuel and alternates are needed when clouds are below 1000ft or visibility is below 2SM or thunderstorms are forecast.

  16. Deicing Chart Delta Meteorology

  17. Deicing Chart Delta Meteorology

  18. Hurricane Chart Delta Meteorology

  19. Deicing Chart Delta Meteorology

  20. Long Range Planning Forecast – Day 1- 5 Delta Meteorology

  21. Delta Meteorology Provides: • Flight Planning System uses GFS Wind forecast. • Back-up source is UKMO. • Also Supply: • Radar • Satellite • Lightning • Charts • Text Data (METARS, TAFS, SIGMETS, etc) Delta Meteorology

  27. My weather radar became inop. Can I continue to my destination? Will that broken line of thunderstorms become solid? What does that unusual code in the TAF/METAR mean? What is the best alternate? What do you think about the SIGMET? Delta Meteorology
