Mixing and transport in correspondence of a meandering jet are investigated. The large-scale flow held is a kinematically assigned streamfunction. Two basic mixing mechanisms are considered separately and in combination: deterministic chaotic advection induced by a time dependence of the flow, and turbulent diffusion described by means of a stochastic model for particle motion.

Abstract
Mixing and transport in correspondence of a meandering jet are investigated. The large-scale flow held is a kinematically assigned streamfunction. Two basic mixing mechanisms are considered separately and in combination: deterministic chaotic advection induced by a time dependence of the flow, and turbulent diffusion described by means of a stochastic model for particle motion.File in questo prodotto:
