Tracer particles are emitted in bunches from localized sources smaller than the Kolmogorov scale. We report the first quantitative evidence, supported by an unprecedented statistics, of the deviations of relative dispersion from Richardson\u2019s picture. Deviations are due to extreme events of pairs separating much faster than average, and of pairs remaining close for long time. The two classes of events are the fingerprints of complete different physics, the former dominated by inertial subrange and large-scale fluctuations, and the latter by dissipation subrange. A comparison of the relative separation in surrogate white-in-time velocity field, with correct viscous-, inertial-, and integral-scale properties, allows us to assess the importance of temporal correlations along tracer trajectories.<\/p>\n<\/div>\n<\/div><!-- kcite active, but no citations found -->\n<\/div> <!-- kcite-section 463 -->","protected":false},"excerpt":{"rendered":"<p>Extreme Events in the Dispersions of Two Neighboring Particles Under the Influence of Fluid Turbulence Phys.
