PS006:
Recent Advancements in Stratified Turbulent Mixing


Session ID#: 28090

Session Description:
This session will explore recent developments in understanding mixing in stratified turbulent shear flows and its role in ocean circulation. The significance of mixing to the ocean energy cycle has long been recognized. While pioneering work developed a basic understanding of turbulence generated by shear instabilities and its efficiency in overcoming stable stratification, significant advancements have been made in recent years. A new framework based on the concept of Available Potential Energy has shed light on the role of mixing in the ocean energy cycle and its efficiency in flows driven either by shear or convective overturning, both characteristic of intermittent ocean turbulence. Meanwhile, new mechanisms for the development of shear instabilities are being discovered through numerical modeling and observations. In addition, meta-analyses of increasingly resolved DNS and ocean microstructure are leading to improved mixing parameterizations for use in ocean models and interpreting observational data. The talks in this session will span theory, experiments, modeling, and observational approaches to discuss recent advancements, new techniques and outstanding questions in turbulent mixing. We encourage submissions focusing on mixing across a range of ocean scales and settings, including global, coastal and estuarine, and its influence on biogeochemical processes.
