Dr. César Sauvage

Postdoctoral Investigator
Physical Oceanography Department



Research Interests

I'm interested in air-sea interactions and processes and how it is related to climate. Through coupled ocean-atmosphere-wave modeling my focus have been over regional scales and/or the forecast of extreme events.

In the framework of the ATOMIC/EUREC4A project the aim of my postdoctoral research is to improve our understanding of the role of ocean mesoscale eddies and fronts in the surface fluxes of momentum, heat, and freshwater in the northwest tropical Atlantic. I am in particular investigating how the eddy-mediated air-sea fluxes relate to ocean boundary layer mixing, low-level clouds, and regional climate.
