Scope 
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.
