Climate models are sensitive to the rate of CO2 and heat uptake into the ocean. “Storms” in the upper ocean regulate this interaction with the atmosphere; however, global models fail to accurately capture these processes dominating the turbulent submesoscales (<1km). The developed novel high-performance computational fluid dynamics (CFD) simulations and advanced mathematical data analysis techniques now help climate models represent these unresolved scales. These simulations enabled greater understanding of the role that one such oceanic “storm” — Symmetric Instability — plays on the atmosphere–ocean communication.
Submesoscale Instability and Turbulent Mixing in Frontal Regions of the Upper Ocean
- Numerically investigated a convective inertial-like instability in strong oceanic fronts responsible for enhanced mixing of heat, CO2, and other biogeochemical tracers.
- Modelled the interactions between instabilities and turbulence in frontal regions to understand their influence on long-term dynamics, working with Professor John R. Taylor in the Atmosphere–Ocean Dynamics Group.
- Collaborations across 5 international institutions and between observational, theoretical, & computational scientists comprise the holistic SUNRISE project.
