気候変動および気候変化に影響を及ぼす大気海洋相互作用の解明
(English)
Understanding of ocean-atmosphere interaction affecting climate variability and change
Overview of your research
(Japanese)
大気と海洋は海面において熱・水・運動量を交換することによって気候の形成に重要な役割を果たしています。このような大気海洋相互作用は、数十年以上の長期的な時間スケールを持つ気候変動や気候変化と関わっていること考えられていますが、そのメカニズムや地域性など不明な点が多く残されています。私の研究では、歴史的な船舶観測データの解析と気候モデルシミュレーションによって、気候変動・変化に影響を及ぼす大気海洋相互作用のメカニズムを解明していきたいと思っています。
(English)
Exchanges of heat, water, and momentum between the ocean and atmosphere play an important role in the climate formation. Such an ocean-atmosphere interaction is believed to cause climate variability and change on multi-decadal time scales. However, its mechanisms and regional characteristics remain unclear. My research objective is to figure out the mechanism of ocean-atmosphere interaction affecting climate variability and change by analysing historical ship records and climate model simulations.
