| Outline of Final Research Achievements |
This study was constructed by the following research elements; (1) development of an ocean current/tidal energy device and wave amplification device that can be operated under various wave and current conditions, (2) analysis of the meteorological and ocean disaster risks in a future climate, (3) understanding of the mechanisms of the air-sea heat exchange that is necessary for the accurate estimation of the ocean climate in future and (4) basic study to propose an evaluation index for evaluating the sustainability of a marine energy project. This study provided basic information to plan a sustainable marine energy project in a future climate.

| Academic Significance and Societal Importance of the Research Achievements |
地球温暖化に伴う気候変動により，今後大気側では低気圧が強大化，海側ではそれに付随して極端な高波等の海象条件が頻発化していくことがほぼ確実と言われているが，海洋エネルギー事業の今後数十年に渡る持続可能な計画を行うためには海象条件の将来変化を正しく推定しなければならない．本研究は大気海洋間相互作用の物理過程を正当に評価し未経験の将来の気象海象の高精度推定に貢献し，現在主流の経験的バルクモデルに代わる新たな大気海洋モデルの構築を経て，より現実的かつ持続可能な海洋エネルギー事業計画，評価へと繋げようとするところに学術的，社会的意義がある．
