Assessment of wave power stability and classification with two global datasets

ABSTRACT

Global distribution of the wave climate and energy using a re-analysis dataset provides the opportunity to study spatio-temporal variation of different parameters, and offers inputs for future sustainability plans. The study assesses two global scale products ERA5 and ERA-Interim, evaluating differentiation in wave climate and energy parameters. Results compare the performance globally and analyse the rate of change for wave power and its persistence characteristics. Based on results for the spatial distribution and rate of change for wave characteristics, wave power and joint distributions are expected to increase. The study provides novel information with a wave energy development index and rate of change globally, suggesting the most appropriate areas for further assessment based on the discussed criteria.
