Abstract

Using a light scattering technique, we find that large density fluctuations in an air jet are clustered in time. A phase-space embedding allows us to propose a simple (S-shaped) manifold underlying the phase-space structure. In this context the temporal complexity naturally arises as stochastic fluctuations are added to the deterministic part of the model.
