Tracer Diffusion and Clustering in Random Nondivergent Flows
As we have seen, clustering of the field of inertialess tracer requires that the velocity field of hydrodynamic flow was necessarily divergent. The common practice of atmospheric physics and physics of ocean consists in consideration of many problems under the assumption that the medium is incompressible, which means that the corresponding velocity field is nondivergent. Despite this assumption, clustering can occur in a number of cases, and we consider them in what follows.
