Statistical properties of scale-dependent fluctuations of velocity (left column), magnetic field (middle column), and number density (right column) in different ISM phases. The fluctuations are computed as the square root of the second-order structure function for each quantity, shown separately for the WNM (T  >  5000 K), UNM (200 K <T <  5000 K), CNM (T  <  200 K), and total ISM (including all phases). Dashed and dashed–dotted reference lines indicate slopes of 1/3 and 1/2, corresponding to Kolmogorov and Burgers turbulence scaling, respectively. The shaded areas represent the standard deviation over the realizations. The numerical dissipation scale r_dis is around 0.5 pc.
