N2 - In this Letter, we suggest that the transport properties and dissipation rates of a wide class of turbulent flows are determined by the random occurrence of coherent events that correspond to certain orbits which we call homoclinic excursions in the high dimensional strange attractor. Homoclinic excursions are trajectories in the non-compact phase space that are attracted to special orbits which connect saddle points in the finite region of phase space to infinity and represent coherent structures in the flow field.
