    "abstract": "The special problem of transport in 2-dimensional divergence-free stochastic\nvelocity fields is studied by developing a statistical approach, the nested\nsubensemble method. The nonlinear process of trapping determined by such fields\ngenerates trajectory structures whose statistical characteristics are\ndetermined. These structures strongly influence the transport.",
