Distribution of α and velocity time series for various values of α. a The PDF of α for Θ = 3τη; the right tail of the PDF is accurately fitted by a log-normal distribution (dotted line). b–d Examples of velocity components u(t) for trajectories with fixed values of α(t0) (the corresponding bins are highlighted in panel a, and colors correspond to the ones in Figs. 3 and 4). Oscillations of the Lagrangian velocity components increase with α
