Time dependent dynamical systems and geophysical flows
... A general physical lesson from our analysis is that focused Lagrangian predictions for a geophysical flow can be feasible even if global Eulerian (i.e., velocity based) predictions are unrealistic. We need to ...

Particle clustering and subclustering as a proxy for mixing in geophysical flows
... Abstract. The Eulerian point of view is the traditional theo- retical and numerical tool to describe fluid mechanics. Some modern computational fluid dynamics codes allow for the efficient simulation of particles, in ...
