Spatial and temporal variability of nearshore wave energy resources along Spain: methodology and results

A global framework, than can be applied worldwide, has been developed to determine waver energy resources at shallow water with high spatial and long temporal resolution in order to analyze the seasonality, interannual variability (correlation of wave power with climate-related indices, such as the North Atlantic Oscillation) and spatial long-term trends along the Spanish coast. The proposed methodology combines instrumental and numerical databases, wave numerical models (dynamical downscaling) and sophisticated mathematical tools (statistical downscaling), which includes a selection algorithm and an interpolation technique to reconstructed time series. The validation of the results in deep water and coastal buoys locations confirm the ability of the methodology developed.
