Fine scale turbulence: theory, models and observations

Turbulence and mixing in stratified geophysical flows provides a critical physical control on the vertical transport of heat, momentum, and tracers. The need for better parameterisation of turbulent processes, particularity in oceanographic and atmospheric models remains strongly recognised. Recent work has made huge advancements in our understanding through the use of DNS and LES modelling and new observational techniques such as the microstructure glider and ADCP processing techniques allow for a greater range of spatial and temporal scales to be explored in stratified turbulence. 

In this session we invite abstracts from all aspects of turbulence research; from surface and bottom boundary processes, from air-sea interactions to pycnocline dynamics. We aim to bring together researchers from a theoretical, modelling and observational background to discuss hurdles and approaches to turbulence parameterisations, including the dependencies of flow parameters on turbulence, the identification of forcing mechanisms on turbulent production and the collapse of turbulence statistics via appropriate nondimensionalisation.
