PO14G:
Oceanic Energy Pathways: From the Global Circulation to the Submesoscale III Posters


Session ID#: 11459

Session Description:
Ocean circulation involves strong nonlinear coupling between processes and structures over a wide range of scales. This session focuses on dynamics related to scale interactions, ranging from global down to the sub-mesoscale. Such interactions play a primary role in determining budgets of momentum, heat, carbon, and other biogeochemical tracers in the ocean, which regulate Earth’s climate.  A promising approach to better understand dynamics at various scales, as well as their interactions, is to consider their energetics. Yet, significant uncertainties remain in our understanding of the oceanic energy pathways, from the global circulation to loss of balance at the sub-mesoscale. Understanding energy transfer across scales is fundamental not only for developing a more complete description of ocean dynamics, but also for the formulation of parameterizations in ocean climate models. In this session we invite discussions of theoretical, observational and modeling studies addressing the above issues pertaining to energy transfer across scales. Specific processes of interest include, but are not limited to, mesoscale and sub-mesoscale instabilities, eddy-mean flow interaction, interactions of the mesoscale with topography, and the transfer of energy between the balanced flow and internal waves.
