Dynamical System Methods for Oceanic and Atmospheric Flows (Part I of II)

Numerical simulations of atmospheric and oceanic flows are reaching a stage where quantitative comparisons with real data are possible. While this progress constitutes a striking confirmation of the validity of the basic models, like the Primitive Equations, sometimes it falls short of enhancing our understanding of the basic mechanisms at play for certain phenomena. To gain some insight it is still useful to study simpler models that target a specific mechanism expected to be important. It is in this context that dynamical systems methods can be effective. The minisymposium's aim is to provide several examples in this direction.
