Research Interest

The ocean is a turbulent fluid in motion at a multitude of spatial and temporal scales, ranging from circulation to the scale of ocean basins to the smallest eddies of the order of one centimeter. Because of the non-linearity of equations governing ocean movements, all scales interact with one another. However, numerical models of global ocean circulation used to predict climate change can not solve horizontal scales of less than a few tens of kilometers. Their collective effects are represented by rather crude parameterizations, which often do not take into account the dynamics of unresolved movements. The ocean is a turbulent fluid in motion at a variety of spatial and temporal scales, ranging from the global circulation to the scale of oceanic basins down to the smallest vortices of centimeter-scale. Due to the non-linearity of the equations of oceanic motions, all scales interact together. Yet, oceanic general circulation models used to predict climate change. Their collective effects are represented by rather crude parameterizations, which often take into account the dynamics of the unresolved motions. My research interests have therefore focused on observing sub-mesoscale oceanic motions, in order to better understand their dynamics and to test and improve their parameters.
