Center for Coastal Physical Oceanography

2011 Spring Seminar Series


Robert E. Tuleya
Center for Coastal Physical Oceanography, Old Dominion University

Monday, March 21, 2011
3:30 PM
Room 3200, Innovation Research Park Building I


HWRF, the next generation Hurricane Weather and Forecasting system, was developed in the WRF (weather research and forecasting) community modeling standards and was implemented operationally by the National Weather Service (NWS) in 2007. This coupled (atmosphere and ocean) system was meant to replace the GFDL hurricane modeling system, which has been utilized since 1995. This talk will describe the development of the system and how it fits into the current forecast guidance utilized by the NWS and the National Hurricane Center. The physical components of the model as well as the pre- and post-processing procedures will be described. The skill of the model in predicting track and intensity and other parameters will be described and compared with other operational guidance tools.


Robert (Bob) Tuleya retired in 2002 from NOAA's Geophysical Fluid Dynamics Laboratory (GFDL) after 31 years of federal service. While at GFDL, he worked in various positions in the Hurricane Dynamics Group, initially as a Research Associate and eventually became Group Head. He is presently working as a NOAA visiting scientist at CCPO in developing and upgrading the next generation Hurricane Weather and Research Forecast system (HWRF), which was implemented in 2007. He continues to study the effect of global climate change on hurricane intensity and frequency with his colleagues at GFDL. He has served on various committees, including the American Meteorological Society (AMS) Committee on Hurricans and Tropical Meteorology and the USWRP research committee on Hurricane Landfall. He is currently on the regional model and diagnostics committees of HFIP (the Hurriane Forecast Improvement Program).
