| Outline of Final Research Achievements |
Yorimawari-wave in Toyama Bay is an anomalous wave phenomenon that has been known for a long time, and has been described in documents from the Edo period. In this study, it is elucidated from the viewpoint of wave dynamics how the swell attacking Toyama Bay becomes huge in the coastal area, and from the viewpoint of atmospheric dynamics, how the 2008 case caused the largest coastal disaster in history.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は，これまで未解明であった寄り回り波の力学過程や2008年の極端現象を説明し得るものであり新規性が極めて高く，また本解析で得られた知見から寄り回り波に対応した防波堤等の海岸構造物設計などが可能となることから，実務的な観点からも極めて重要な研究成果である位置づけられる．
