This session on geophysical fluid dynamics is concerned with nonlinear wave processes of whatever scales, wave-related instabilities and wave-turbulence interactions.
The areas of interest include nonlinear dynamics of surface water waves with and without wind, internal waves, wave-turbulence interactions, solitons, wave generation by currents in ocean and atmosphere, nonlinear stages of flow instabilities, critical layers, wave-induced pattern formation, including morphodynamic, etc. Biological phenomena related to underlying fluid dynamics are also within the scope of the session. The aims of the session are to discuss the mathematical models on which the description of a variety of nonlinear geophysical phenomena can be based, investigate specific physical mechanisms of these phenomena, and discuss their observations. Theoretical, numerical, experimental and observational.
