  1. Weather Support for Weapons of Mass Destruction (WMD)

  2. Because you need to expect the unexpected!!!

  3. Meteorological support for real-time and • forecasted variables (e.g., wind, precipitation, • temperature, etc.) • 2) Meteorological support for CAMEO/ALOHA and • access to output from a national dispersion model • HYSPLIT (Hybrid Single-Particle Lagrangian • Integrated Trajectory) 3) Support from the Scientific Support Coordinator (Great Lakes and Western Rivers) 4) Support from NOAA-Seattle 5) NOAA Weather Radio – all hazards capability

  4. Meteorological support for real-time and forecast weather elements Surface observations (wind, temperature, visibility, etc)

  5. Wind profile from the Doppler radar

  6. Thermodynamic atmospheric profile radiosonde (balloon)

  7. Forecast model Fields In this case – surface pressure and precip

  8. Satellite

  9. Radar – precipitation timing and intensity

  10. Forecasted 12 hour Winds at 1 km and 2 km

  11. And of course, there’s always that tried and true method of forecasting!!!!!!!

  12. A little about concentration or exposure The NWS can help with at least two important variables critical for concentrations/exposure (Wind & Stability)

  13. Relationship between wind and concentration Wind is inversely proportional to the concentration! -the stronger the wind, the lower the concentration -the weaker the wind, the higher the concentration

  14. Stability – the downwind plume from an event will be extremely dependent on the structure of the temperature profile in the vertical (the stability) Stable atmosphere stays very confined In the vertical Unstable atmosphere over stable stays confined above surface, but expands aloft

  15. Unstable atmosphere spreads vertically with time and distance Very unstable atmosphere spreads very widely over the vertical Stable atmosphere over unstable Starts with little vertical Extent, but with mixing Expands greatly

  16. 2) Support for CAMEO and access to HYSPLIT CAMEO/ALOHA – designed to estimate local impacts and weather conditions do not vary(normally run by local emergency management) -basically near ground -time scale of one hour after event -distance of 10 km downstream HYSPLIT – designed to estimate long-range transport and dispersion and uses operational weather models as input(normally run by NWS, NOAA) - elevated/ejected releases & large scale diffusion -time scale = several hours to several days -distance = significant distances downstream

  17. CAMEO (Input)

  18. CAMEO (Output)

  19. HYSPLIT Trajectory output

  20. HYSPLIT Concentration output for 2 hours ending at 2000 UTC

  21. HYSPLIT Concentration output for 2 hours ending at 2200 UTC

  22. HYSPLIT Concentration output for 2 hours ending at 0000 UTC

  23. HYSPLIT output loop of concentration over an 6 hr period based on model data from 20 Feb 2007 Release/event point = Southwest of Columbus

  24. HYSPLIT output loop of deposition over an 6 hr period based on model data from 20 Feb 2007 Release/event point = Southwest of Columbus

  25. NOAA In Your Neighborhood Work together on events X X = Scientific Coordinator Weather Forecast Office (122) River Forecast Center (13) NCEP Center (9) Center Weather Service Units (22) NESDIS CoastWatch Nodes (9) NOS HazMat Office NOS Coastal Services Center NESDIS Nat. Climatic Data Center CoastWatch Nodes

  26. Scientific Support Coordinator (Great Lake and Western Rivers) is located in Cleveland and the NOAA – Seattle (NOS HAZMAT office) generally work together if there is an “event”. -EPA usually gets involved with small chemical spills (events) and NOAA with the large ones. -NOAA will also be brought in on spills/releases on the larger rivers and can support plume dispersion through CAMEO/ALOHA . -Coast Guard for barge or ship releases. NOAA’s involvement in any particular event generally depends on if the EPA, Coast Guard, or EMA calls them. NOAA/NOS 24 hour operations # = 206-526-4911

  27. NOAA-NOS Website (response.restoration.noaa.gov)

  28. NOAA ALL Hazards Weather Radio www.weather.gov/nwr Broadcasts are found in the public service band at these seven broadcast frequencies (MHz):

  29. All Hazards NOAA Weather Radio in Ohio

  30. At times, the WSR88D Doppler Weather Radar can also aid in The monitoring and tracking of non-meteorological events. Marsh Fire in Mentor (Lake County) 28 April 2003

  31. Space Shuttle debris plume – 01 Feb 2003

  32. TWA Flight 800 debris field

  33. Plume from large tire fire in Washington County, PA

  34. The END….hey, remember, be careful out there!
