Outline of Final Research Achievements |
We estimated wave energy resources around Japan using in-situ wave data, wave and atmospheric reanalyses data, and numerical wave model. In the assessments of wave energy resources, we estimated the uncertainty of wave energy due to the difference in near-surface wind forcing. We also investigated the changes in the Pacific wave climate since the mid-1990s. We found that changes in the Pacific wave cliamte are attributable to recently strengthened trade winds and La Nina-like conditions in the tropical Pacific. Furthermore, we investigated the impact of assimilating satellite data into atmospheric reanalyses on trends in ocean surface winds and waves. We found that the satellite data assimilation impacts the long-term trend of wave energy significantly.
