Multi-scale turbulent mixing of the ocean surface boundary layer

Session ID#: 254483

Session Description:
The turbulent ocean surface boundary layer (OSBL) communicates heat, mass, and momentum between the atmosphere and ocean interior, hosts the majority of oceanic primary productivity, and plays a key role in the evolution of the earth system spanning from diurnal to centennial time scales. The boundary layer turbulence driven by surface winds, waves, and cooling (1cm-100m) co-exists with a complicated lateral flow and density field associated with submesoscale (500m-10km) and mesoscale (~100km) processes, such as eddies and fronts. Understanding how processes on these scales and their interactions drive upper ocean turbulence continues to be critical for understanding the earth system.

This session aims to bring together observational, numerical, data-driven, and theoretical investigations across this vast range of scales, giving the community an opportunity to discuss and understand the complexity of mechanisms through which these scales are connected and how the pathways between them are realized. We are particularly interested in studies that conceptualize these multi-scale turbulent regimes within a broader framework, including the advancement of parameterizations to emulate these processes, the development of novel observational or analytical tools to quantify them, and the assessment of their impacts on the wider ocean and Earth systems at regional and global scales.
