A stochastic model for turbulent vertical transport
Scott Wunsch, Sandia National Laboratories, Livermore, CA; and A. R. Kerstein
The One-Dimensional Turbulence (ODT) model is a single-column simulation in which vertical turbulent transport is modeled by an unsteady, stochastic advective process, rather than the customary representation by a diffusive process. Unlike conventional single-column models, ODT resolves small-scale, unsteady motions and transport processes in the atmospheric boundary layer. ODT has been validated against laboratory data for a number of different convective, stably-stratified, sheared, and reacting flow configurations. This presentation will provide a concise summary of the ODT approach along with applications to convection and the cloud-top entrainment instability.
