Abstract
Lagrangian methods have been used to describe turbulent diffusion since G.I. Taylor's classic work and are now well established at a practical level in applications in the atmosphere. Nevertheless there remain fundamental issues associated with the development of Lagrangian models for turbulent transport and diffusion and in our recent work we have attempted to address some of these issues using direct numerical simulations. Although this is a powerful approach, it necessarily involves consideration of finite Reynolds number effects that are generally ignored in the atmosphere. Here we give a brief overview of some of this recent work underpinning Lagrangian modelling of turbulent dispersion in the atmosphere.
