Our KS results are consistent with the physical picture that particle trajectories are more/less autocorrelated if they are smoother/rougher as a result of encountering less/more straining stagnation points, thus leading to enhanced/reduced turbulent diffusion.4 pages, 3 figures, submitted to PRLChaotic DynamicsA new Eulerian-Lagrangian length-scale in turbulent flowstext
