Presentation Transcript

  1. Local Modeling at NOAA/NWS Marquette Incorporating TAMDAR Data 11 April 2005 GLFE Meeting Tom Hultquist Science & Operations Officer NOAA’s National Weather Service, Marquette, MI thomas.hultquist@noaa.gov 906-475-5782 x766

  2. Model Configuration • Local Analysis & Prediction System (LAPS version 0-24-3) used for hourly data assimilation/analyses • LAPS cycles each hour with the WRF-ARW (version 2.0.3.1), providing WRF with its initial conditions and using the WRF forecast as its (LAPS) first guess • LAPS is ingesting a combination of MADIS and AWIPS data comprising all “basic” data (METAR, maritime, mesonet, RAOBs, profiler, satellite imager, aircraft w/TAMDAR, etc…) • LAPS is not currently running in diabatic “hot start” mode due to technical problems, but a solution to this problem is being sought

  3. Model Configuration • LAPS utilizing 22 vertical levels with 15km grid spacing • WRF-ARW utilizing 31 vertical levels with identical grid spacing (15 km) and domain • Model top at 50 mb • Kain-Fritsch (new) cumulus scheme • Lin et al. 5 class microphysics scheme • RRTM longwave radiation scheme • Goddard shortwave radiation scheme • Noah land surface model • YSU PBL scheme

  4. Model Domain & Topography

  5. Access to Model Output • Model output is available via the web • Internally (within NWS), the output is available at: • http://wseta.mqt.noaa.gov/SOO/wrf_html/wrf.php • The output is available to anyone at: • http://www.crh.noaa.gov/mqt/data/wrf_html/wrf.php • Display of static images and loops (one hour temporal resolution) is available • Basic diagnostic fields are available as well as a few aviation parameters • Soundings are available for a number of locations in Wisconsin and Upper Michigan (if you would like a sounding generated for another site, contact thomas.hultquist@noaa.gov)

  6. Access to Model Output (web-based interface)

  7. Quick Forecast Comparison 9-hour LAPS/WRF-ARW Forecast Valid for KGRB at 12 UTC 12 April 2005 KGRB RAOB Valid at 12 UTC 12 April 2005

  8. Archive Efforts • A 14 day running archive is maintained for raw data files and web-based model output • Data is permanently archived for “cases of interest” • Thus far, two cases have been archived (a lake effect snow event and a heavy rain event) • Forecasters (and other SOOs) are encouraged to contact thomas.hultquist@noaa.gov with interesting cases so that they can be permanently archived for later study • Model simulations with/without TAMDAR data will be conducted on archived “cases of interest” • Information on the project and results from a few case studies will likely be presented at the U.S./Canada Great Lakes Operational Meteorology Workshop scheduled to take place in Grand Rapids, Michigan, September 14-16, 2005.

  9. Questions • Questions, comments, and/or suggestions regarding this effort should be directed to: • Tom Hultquist, Science & Operations Officer NOAA’s National Weather Service 112 Airpark Drive Negaunee, MI 49866 (906) 475-5782 x766 thomas.hultquist@noaa.gov
