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

and shapes.

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.
