Outline of Research at the Start

2019年台風19号や2016年台風10号などの台風を要因とした大雨災害のリスクを大量アンサンブル気候予測データを用い統計的かつ力学的に流域スケールで分析する。 台風がもたらす降雨量はその経路に大きく依存することから、数十年間の観測実績のみからの大雨リスクの把握は困難だと考えられる。また、勢力の強い台風の増加が将来は予測されているが、どれほど降雨量を増加させるかは明らかではない。本研究では、数千年分の高解像度気候予測データを活用し台風の経路を網羅的に考慮し、気候変動を踏まえた治水対策の検討において重要となる日本全国での各支川流域における台風を起因とする大雨リスクとその将来変化を明らかにする。

Outline of Final Research Achievements

The characteristics of heavy rainfall caused by tropical cyclones were examined based on the relationship between tropical cyclone tracks and rainfall intensity. Ensemble climate data, consisting of several thousand years of data in total, was used to clarify the relationship between the location of tropical cyclones and rainfall intensity in the basin. As a result, a dangerous area was identified where the typhoon would be located over the river basins in Japan. In addition, the rainfall amounts when the typhoon path is shifted from east to west were determined from ensemble climate data by focusing on Typhoon Hagibis (2019). Furthermore, a classification method for spatiotemporal rainfall patterns was developed. The relationship between the classified heavy rainfall patterns and typhoon paths was clarified. These results are expected to contribute significantly to the study of future flood control measures using ensemble climate data.

Academic Significance and Societal Importance of the Research Achievements

台風による大雨は甚大な被害をもたらす上、気候変動による雨量の増大も危惧されることから台風による大雨の特徴の理解は重要な過大である。本研究では台風の位置と流域スケールの降雨強度の関係を5km解像度のアンサンブル気候データの台風経路と大雨の情報を用いることにより明らかにした。また、アンサンブル気候データを活用した過去の台風がもたらし得た降雨量やその温暖化応答の推定手法を初めて提案した。さらに、本研究では災害のパターンや規模に直結する降雨の時空間的なパターンの分類手法を提案することで、台風経路別の災害シナリオを検討可能とするなど、新しい治水対策の検討につながる成果が得られた。
