Wednesday, September 12, 2018. 12:00PM. Atmospheric and Water Dynamics Modeling and Other NOAA Activities in the Laurentian Great Lakes. Brent Lofgren, NOAA Great Lakes Environmental Research Laboratory. Sponsored by NOAA GFDL. More information here.


The Laurentian Great Lakes—Superior, Michigan, Huron, Erie, and Ontario—contain 20% of the world’s surface fresh water. They provide shipping, domestic and industrial water, recreation, and commercial fishing for over 30 million residents of the drainage basin. The NOAA/OAR’s Great Lakes Environmental Research Laboratory provides science related to the dynamics of the lakes and regional atmosphere, hydrology of the watershed, ecosystem dynamics and environmental factors affecting native and invasive species, and develops and maintains instrumentation to monitor the lakes. Other NOAA offices also provide local weather services, satellite data analysis, habitat restoration, and National Marine Sanctuaries within the 7.5 Great Lakes states. This seminar will give an overview of these activities before moving to more specific topics. It will also include a brief summary of problems encountered in projecting lake levels under climate scenarios, in part due to lack of faith in results derived by GFDL and its peers. Some results from dynamical downscaling of GFDL CM3.0 using WRF will also be presented. Finally, Lofgren will present work that they did during their visit to GFDL in using the Finite Volume Community Ocean Model (FVCOM), driven by output from a historical time slice of GFDL CM 4.0, in terms of hurdles, technical requirements for input to FVCOM, lessons learned, and planned improvements and enhancements.
