It is understood that climate change shall affect the sustainability of Oklahoma’s wind energy resources by causing an overall increase of median wind energy density across the state. However, there is a lack of consensus on why this change of sustainability would occur. Observational studies have indicated that a link exists between the speed and frequency of the low-level jet (LLJ) and the magnitude of energy generation from wind turbines in various locations. This provides a precedent to determine whether climate change’s impacts on the LLJ can explain previously projected changes of Oklahoma’s wind energy resources. The proposed method is to apply projections of wind speed change from several General Circulation Models (GCMs) to Oklahoma Mesonet observations, consequently creating high resolution datasets for analysis of the response of wind energy resources in the Oklahoma Panhandle to the effects of climate change on the LLJ (as indicated by the GCMs). These analyses have conducted on diurnal, seasonal, and spatial scales. This shall allow for the future effects of the LLJ on several sustainability indicators - median wind energy density, ramp events, and cut-in/cut-out events - to be verified. Consequently, conclusions can be made about why climate change will affect Oklahoma’s wind energy resources.
