Goals Our overall goal is to build a Global Climate Model [GCM] to study the dynamics of Saturn's troposphere and stratosphere [Spiga et al. EPSC 2014, this issue]. A GCM consists basically in an interface between an hydrodynamical core which computes numerically the solution to Navier-Stokes equations, and physical parameterizations in which the various forcings (radiative transfer, latent heat exchanges within clouds, subgrid-scale mixing) applied to the atmospheric fluid are calculated. Thus, a first step was to develop tailored physical parameterizations for the Saturn's atmosphere . We report here on part of the second step to build our Saturn GCM: testing the LMDz dynamical core  in the fast-rotating conditions of gas giants' atmospheres.
