Spectral analysis of the global-scale kinetic energy decomposed into spherical harmonics of spatial order n for our Jupiter-DYNAMICO simulations. The top left plot shows the dry simulation, and the top right, bottom left, and top left shows the 1 SA, 3 SA, and 5 SA moist simulations, respectively. Details on the computations of this diagnostic are reported in Cabanes et al. (2020b). The axisymmet-ric component (i.e., the contribution of zonally averaged zonal jets) is represented in blue, and the nonaxisymmetric component (i.e., the contribution of the eddies) is represented in red. The distribution of the kinetic energy between the axisymmetric (the jets) and nonaxisym-metric (the eddies) parts of the flow can be computed through the decomposition of the horizontal wind fields over the spherical harmonics. The expected regimes for the axisymmetric component (blue) and the eddy component (red) are provided as dashed lines in the figure.
