We consider the formation of large scale structures (zonal jets and
vortices), in planetary atmospheres. We will prove that modern
statistical mechanics approaches predict the outcome of the very complex
dynamics of geostrophic turbulence and predict jet and vortex structures
Based on the equilibrium statistical mechanics of the quasi-geostrophic
dynamics, we will discuss a model of the Great Red Spot of Jupiter, and
of other Jovian vortices. We will discuss the non-equilibrium
statistical mechanics of Jupiter jets.
Large deviation theory is the basic mathematical tool on which those
results are built. We will discuss the relations between large deviation
and fluid mechanics at a basic level.
