Geophysical flows are highly turbulent, yet embody large-scale coherent structures, such as ocean rings, jets, and large-scale circulations. Understanding how these structures appear and predicting their shape are major theoretical challenges. The statistical mechanics approach to geophysical flows is a powerful complement to more conventional theoretical and numerical methods. In the inertial limit, it allows to describe, with only a few thermodynamical parameters, the longtime behavior of the largest scales of the flow.
