  1. Climatological Research Collaborations Between NWS Tallahassee and the Florida State University Tim Barry and Irv Watson National Weather Service Tallahassee, Florida

  2. Florida as well as other Gulf Coast Locations Unique Summertime Sea Breeze Patterns of convection depend on moisture and low-level flow Use of Lightning, Radar, and Precipitation Climatologies in GFE

  3. Flashes per km2 per regime day Lightning distributions over the Florida peninsula Todd P. Lericos (SCEP), Henry E. Fuelberg, and A. I. Watson Weather & Forecasting, 2002. All Flows Combined 10 years of Lightning Data Lightning Flash Density May through September during 1989-1998 850 mb Mean Height Field .02 0.2 0.5 0.8 1.2 1.5 1.8 2.1 2.4 >2.4

  4. 24-hr loop All Flows/ All Regimes

  5. Incorporating Mesoscale Lightning Climatologies in the NWS IFPS/GFE Forecast Routine along the Gulf Coast Jessica R. Stroupe (SCEP), Henry E. Fuelberg, Andrew I. Watson Michael C. Koziara, and Stephen K. Rinard 14 years of Lightning Data

  6. 24-hr loop All Flows/ All Regimes

  7. Patterns of convection depend on moisture and low-level flow

  8. Calm Wind Regime Hourly Animation

  9. Use of Lightning Climatologies in GFE Grid Manager Spatial Editor Figure 6. By means of a procedure in the Edit Actions Dialog Box, lightning data are converted into a QPF forecast.

  10. Radar Climatologies High resolution historical database of gage/radar precipitation for the state of Florida and southern Georgia Participants: The Florida Department of Environmental Protection (FDEP); Prof. Henry Fuelberg (FSU Department of Meteorology); WFO Tallahassee, Southeast River Forecast Center (SERFC),  NWS Hydrology Laboratory; and U.S. Geological Survey - FL. Currently 4 years of WSR-88D data for SE U.S. Greg Quina and Bryan Mroczka

  11. April-September Jacksonville Mobile, AL Miami, FL Winter Composites are also completed!

  12. Precipitation Climatologies COMET Partners Project To develop 3-, 6-, 12-, and 24-hr Precipitation Frequencies Using Hourly Precipitation Data (HPD) For all NWS Southern Region For approximately 30 years Matthew Sitkowski (NHC SCEP) Undergraduate Assistant Dr. Henry E. Fuelberg Florida State University

  13. 24-hr January 0700-0900 UTC

  14. 12-hr – 0100-1200 UTC January 0700-0900 UTC

  15. 12-hr – 1300-2400 UTC January 0700-0900 UTC

  16. 6-hr – 1900-2400 UTC July 1900-2100 UTC

  17. 3-hr - July July 1900-2100 UTC

  18. Coastal Waters Temperatures • Air temperatures over water – new weather element • Forecasters were not familiar with this • Training had to be done to introduce forecasters • Start with climatologies Data readily available from NDBC Data goes back many years at some buoys

  19. Coastal Waters Temperatures Buoy 42039

  20. Ongoing Studies • The Tallahassee Area Minimum Temperature Study Understand temperature variability across Tallahassee Will collect data through this Spring Will include a Winter Frontal Passage Study • Fog Study Fog Climatology for KTLH completed by Mark Jarvis (WFO Louisville) Current work includes assessment of UPS Fog Study Road weather study includes instrumented communication towers along I-10. One tower (Quincy) has a visibility sensor

  21. Other Collaborations • NWS Class taught each Spring Semester 21 students in class • Student Career Experience Program (SCEP) Work-Study Program 3 SCEPs currently working in WFO • Internship Class – One student per semester • Volunteer Program – Two volunteers

  22. New Studies with Florida State University • COAPS – Relationship between CG lightning across the U.S. during El Nino, La Nina, and Neutral Phases using 15 years of NLDN data • The development of forecast confidence measures using NCEP ensembles and their real-time implementation within NWS graphical forecasts – COMET Cooperative Proposal by Dr. Robert Hart
