Outline of Research at the Start

経験したことの無い低気圧による災害が近年増大しており,その背景には観測資料の不足や気候変動の影響がある.本研究ではこうした捉えどころのない低気圧による高潮や気象津波などの沿岸災害を総合的に取り扱い,その発生過程や特徴を高分解能の観測データや大気・海洋・波浪結合モデル等による解析から明らかにする.確率モデルや人工知能を応用した短期・長期の事前予測手法の開発に取り組む.さらに観測値の不足等から生じる予測の不確実性の幅を定量化し,タイムライン防災に必要な知見を明らかにする.また低気圧の将来変化について全球モデルの予測結果に基づく分析や応用解析を行い,沿岸災害や港湾の静穏性への影響について考察する.

Outline of Final Research Achievements

To understand the uncertainty of real-time typhoon forecasting, we analyzed the forecasts from the Japan Meteorological Agency (JMA) and identified specific characteristics of forecast errors in typhoon properties. We also developed a real-time typhoon probability model. Based on fixed-point observations around Osaka Bay, we established the relationship between the annual occurrence of micro-pressure waves and abnormal tidal levels. The meteorological model results revealed that micro-pressure waves are prominently caused by frontal passage and interactions with typhoons. To examine the impact of cyclone variations on the future climate field, we created a stochastic typhoon model considering a rise of 4°C/2°C. Additionally, we devised a simplified method to assess the risks of strong winds, storm surges, and high-velocity hazards using the output of the stochastic typhoon model. Lastly, we evaluated the future changes in bomb cyclones based on a 150-year forecast.

Academic Significance and Societal Importance of the Research Achievements

台風災害予測の不確実性は減災行動の抑制因子であり,定量化し意思決定に取り込むことでレジリエントな社会創造へとつながる.気象津波の因子である微気圧波を,高精度微気圧計により年間を通じた多点モニタリングした事例は希少で,台風と前線の干渉による微気圧波群の発生などの日本周辺における気象津波の実態解明に貢献した.将来予測の不確実性評価における統計的モデリングの重要性はIPCC AR6でも強調されており,応用範囲の広い高潮・高波の簡易高速推定法を構築したことは影響評価研究を大きく進展させた.これにより大アンサンブル資料に基づく不確実性の幅を示すなどは他に類を見ない成果を提示した.
