Outline of Annual Research Achievements

2022年、シンガポールとナイジェリアのラゴスという2つの熱帯都市で、対流性降雨のメカニズムを調べる研究を行いました。降雨イベントに対する都市の影響を調べるため、過去数十年の降雨パターンを分析しました。その後、さまざまな土地利用シナリオによる数値シミュレーションを行い、極端な降雨イベントに対する都市の感度を調査しました。その結果、大都市圏ではヒートアイランド現象が生じ、大気の低層安定性が低下するため、都市部での収束が進み、周辺地域から都市部へ水蒸気が引き込まれることがわかりました。また、海に近いラゴスやシンガポールの場合、都市のヒートアイランド効果によって風が引き寄せられ、都市上空の海風の収束が促されるため、対象イベント時に異常降雨が強化される可能性があります。研究成果は、 Geophysical Research Letter、Journal of Geophysical Research: Atmosphere(AGU-アメリカ地球物理学連合)、Journal of Applied Meteorology and Climatology(AMS-アメリカ気象学会)などの著名な国際誌に掲載されました、また、アメリカ地球物理学連合(米国、オンライン)、アジア・大洋州地球科学学会(AOGS)(シンガポール、オンライン)、CORDEX SEAワークショップ(タイ、対面式)など複数の国際会議やワークショップで発表されました。
