Time evolution of the mSI (runs: [mSI^*, mSI_τs,5e−2, mSI_τs,2e−1]) are shown with a dotted lines and PSI (runs: [PSI^*, PSI_τs,5e−2, PSI_τs,2e−1]) are shown with solid lines for different peak Stokes numbers τ_s,max. The colour indicates maximum Stokes Number with τ_s = 0.05 in blue, τ_s = 0.1 in orange, and τ_s = 0.2 in green. The top plot shows the amplitude of the largest mode in the shearing box (A sinusoid with wavenumber K_x,z = 30), and the dashed lines and dash-dotted lines show the analytical results calculated with psitools for the corresponding α. The bottom plot shows the normalised mean density at the 99^th percentile for every snapshot.
