Scope 
Oceanic and atmospheric dynamics 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. It provides perspectives for the advancement of sciences in various areas such as turbulence, wind waves, internal waves, Rossby waves, tides, coastal and equatorial boundary processes, mesoscale and submesoscale eddies, meandering of jets and fronts, general circulation, and ocean-atmosphere coupled modes. It has also been and will continue to be benefited by new uses of ideas and methods from such theories as resonance, nonlinear interaction, stability analysis, spectral analysis, probability, statistics, and dynamical systems. In this session, we solicit presentations on 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.
