1. Climate Science Research in Support of the Wind Power Industry Wind resource availability Seasonal prediction Impacts of climate change Environmental impacts Prepared for Visit to ISU by Florida Power and Light

2. In the Upper Midwest, Wind Resources are Influenced by: Seasonal pressure patterns Diurnal temperature stratification Buffalo Ridge Low-level jet El Niño/La Niña (?) Pacific Decadal Oscillation (?) North Atlantic Oscillation (?) Climate change (??)

3. “Given that a 1% error in wind speed estimates for a 100 MW wind generation facility can lead to losses approaching $12,000,000 over the lifetime of that plant, a better understanding of the physical and dynamic processes across the range of scales that create a particular wind climate is needed.” Draft recommendations, DOE Workshop on Research Needs for Wind Resource Characterization, 14-16 Jan 2008, Broomfield, CO
