Outline of Final Research Achievements

This study investigated mechanisms that caused anomalous conditions of the Asian summer monsoon and tropical cyclone activity in the western North Pacific by performing numerical simulations using the Japan Meteorological Agency seasonal prediction model for summers in 2010, 2016, 2018, and 2020. The series of studies provided a comprehensive understanding of the interannual variability of the western Pacific-Indian monsoon and tropical cyclone activity through the interbasin interactions. In addition, the skillful prediction of the Asian summer monsoon and tropical cyclone activity in the western North Pacific one year ahead was demonstrated.

Academic Significance and Societal Importance of the Research Achievements

本課題の研究成果により、夏季のアジア域の季節予測可能性をもたらすアジアモンスーンの変動機構に関する知見が得られた。また、最新の季節予報モデルによる夏季アジアモンスーン及び台風活動の予測可能性の詳細な評価を得ることができた。本研究によって得られた知見は、夏季アジアモンスーンと北西太平洋域の熱帯低気圧の年々変動機構と予測可能性に関する理解を進展させ、それらの長期季節予測の現業化と精度向上に大きく貢献すると期待される。さらに、本研究で特定された、夏季アジアの気候変動に鍵となるプロセスに着目して気候予測モデルの性能評価を行うことにより、更なる気候モデルの改良に貢献すると期待される。
