本セッションでは、海洋および大気中に見られる具体的な現象の中から一般原理を抽出・体系化することによって数理モデルを構築し、それを再び具体的な現象の解釈・予測・パラメータ化につなげるという海洋力学・大気力学の意義を再確認する。このような円環的な思考を通じて、乱流・波動・渦・平均流・ジェット/フロントシステム・境界過程・大循環・大気海洋結合・それぞれの相互作用など、広い分野についての研究発展の見通しが与えられるとともに、共鳴・非線形相互作用・安定性解析・スペクトル解析・確率統計・力学系など種々の理論の利用方法が開拓されることを期待する。観測データや再解析プロダクトの診断手法(機械学習も含む)の開発、生態系モデルや気候・環境問題を含む学際的な研究、力学的に未解明だが興味深いデータの紹介なども歓迎し、新しい発想を生み出す原動力としたい。

This session re-examines the essential role of oceanic and atmospheric dynamics, which aims at abstracting general principles from observed phenomena and constructing a system of mathematical models, thereby leading to the understanding, prediction, and parameterization of those phenomena. This circular approach provides perspectives for advancing research across various areas such as turbulence, waves, eddies, mean flows, jet-front systems, boundary processes, general circulations, ocean-atmosphere coupling, and their mutual interactions. Furthermore, we anticipate the novel application of various theoretical tools such as resonance, nonlinear interaction, stability analysis, spectral analysis, probability, statistics, and dynamical systems. We solicit presentations across observational, experimental, numerical, and theoretical studies of oceanic and atmospheric dynamics and on exploratory use of new ideas and methods, including machine learning. We also welcome presentations on interdisciplinary studies in fields such as ecosystems, climate, and environment, and intriguing but dynamically unexplained data. We aim for this collective effort to be a driving force for new scientific concepts and breakthroughs.
