PS002:
Facing the challenges in interpreting high resolution satellite observations due to the co-existence of internal gravity waves and balanced motions in the world oceans


Session ID#: 28106

Session Description:
Near-inertial waves and internal tides are the dominant modes of high-frequency internal variability in the ocean, and they scatter into a broad-band inertia-gravity wave spectrum. These high-frequency waves are also known to interact with low-frequency motions associated with “balanced” turbulence (including geostrophic mesoscale eddies and sub-mesoscale fronts and vortices with finite Rossby number). Theoretical and numerical studies of the last decade have demonstrated the importance of these interactions for wave dispersion and energy transfer in the 1km-100km scale range, as well as their effects on the spatial variability of mixing and the route to dissipation. Recent studies have further highlighted the potential impacts of these wave-turbulence interactions on not only high-resolution in-situ observations but also high-resolution satellite observations. This concerns SAR images and also observations from future altimetry missions such as the SWOT mission. These impacts point to new scientific challenges for the interpretation of these high-resolution observations in terms of distinguishing waves from balanced currents and deciphering their interactions. The purpose of this session is to review what we know about these interactions, to identify the questions that still need to be addressed, and to consider how to meet these new challenges.
