Theoretical Modelling of Submesoscale Fronts, Waves and Instabilities
Session ID#: 256150
Session Description:
The term 'submesoscale' refers to processes occurring on scales where the effects of rotation and stratification are significant, but not dominant. In the ocean, this typically corresponds to spatial scales of 100m - 10km and timescales of 0.1 - 10 days. Submesoscale flows are complicated, and include a wide range of fronts, eddies, waves and instabilities. These features interact through nonlinear processes, and are believed to enable the downscale transfer of energy from the 'balanced' mesoscale flow to turbulent dissipation. Understanding this energy pathway is an important step to understanding the global ocean energy budget.
Typically, submesoscale processes are not well resolved by large scale climate models due to resolution constraints. As such, a theoretical understanding of these flows is required to build parametrisations representing the feedback of submesoscale dynamics on the large scale flow.
This session will focus on the theoretical modelling of submesoscale flows via reduced models and idealised numerical simulations. We particularly encourage early-career researchers to participate in this session.
