| Outline of Final Research Achievements |
Among the atmosphere-ocean interactions remaining uncertainties in the prediction of extreme weather events, momentum and turbulent flux are observed, and we developed physical models based on field observation. The new physical models were embedded in a coupled atmosphere-ocean-wave model, and their effects were verified. In addition, to predict coastal disasters caused by explosive extratropical cyclones, new prediction models for storm surge and high waves were developed. New models were capable of fast and accurate prediction. Their models were used to evaluate the climate change impact of the extratropical cyclone and the coastal disasters.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の学術的な意義は研究で実施した現地観測，そしてその結果得た新しい物理モデルは約20年来発展していなかった大気海洋相互作用の分野において大きな進展が得られたことにある．その相互作用の効果は台風や爆弾低気圧の予測精度に影響を及ぼすため，日々の気象予報にも貢献する成果と言える．また爆弾低気圧の気候変動影響評価は主に北日本域における防災・減災計画に直結する重要な知見である．これらの成果は本研究が大きな社会的な意義を持つと言える．
