Classical statistics averaged over 30 realisations for (a) power spectrum, (b) vorticity increments (for lags of 1, 4, and 32 pixels), (c) the energy transfer function, ℱ_u, and (d) the enstrophy transfer function, ℱ_w. Green is for the initial conditions (of the syntheses), red for the MuScaTS syntheses (basic run), and blue for the simulations at time t = 2. Shaded areas give the one-sigma error around the mean over the 30 independent realisations (i.e. mean plus or minus standard deviation divided by $\sqrt{30}$).
