Scaling exponents ζ_v^MDPL2(q) derived from the second (large-scale) regime of the velocity field. The concave dependence of ζ(q) on q demonstrates clear departures from monofractal scaling and confirms the presence of statistical intermittency. The dashed curve shows the best-fit UM model, obtained with parameters α ≈ 2 (log-normal multiplicative cascade), C₁ ≈ 0.03, and H ≈ 0.11, indicating weak but non-zero intermittency.
