The role of boundary layers in the global ocean circulation

Colloquium presented by Laure Saint-Raymond (École normale supérieure, Paris)

Understanding the mechanisms that govern ocean circulation is a challenge for geophysicists, but also for mathematicians who must develop new analytical tools for these complex models (which involve in particular very numerous time and space scales). A particularly important mechanism for broad-scale planetary circulation is the boundary layer phenomenon which explains part of the energy exchanges. We will show here through a very simplified model that it allows us to explain in particular the intensification of the western edge currents. We will then evoke the mathematical difficulties linked to the consideration of geometry. Note: the presentation will be in English with transparencies in French.
