One-Layer Turbulent Geophysical Flows
Statistical bounds controlling the total fluctuations in mean and variance about a basic steady 6 state solution are developed for the truncated barotropic flows over topography. Statistical ensemble predic7 tion is an important topic in weather and climate research. Here the evolution of an ensemble of trajectories 8 is considered in the statistical instability analysis and is compared and con...
متن کاملSubgrid modelling for geophysical flows.
Recently developed closure-based and stochastic model approaches to subgrid-scale modelling of eddy interactions are reviewed. It is shown how statistical dynamical closure models can be used to self-consistently calculate the eddy damping and stochastic backscatter parameters, required in large eddy simulations (LESs), from higher resolution simulations. A closely related direct stochastic mod...
متن کاملPlasticity and geophysical flows: A review
The objective of this review is to examine how the concept of plasticity is used in geophysical fluid dynamics. Rapid mass movements such s snow avalanches or debris flows involve slurries of solid particles (ice, boulder, clay, etc.) within an interstitial fluid (air, water). The bulk ehavior of these materials has often been modeled as plastic materials, i.e., a plastic material yields and st...
متن کاملUncovering Transport Barriers in Geophysical Flows
Allshouse, Michael (University of Texas, Austin) Accounting for windage in the identification and classification of FTLE ridges Understanding the transport of contaminants on the surface of the ocean is aided by identifying regions of large Lagrangian deformation. Given that the FTLE field measures the local deformation, its ridges represent the locally maximum repelling structures in the flow....
متن کاملLattice-Boltzmann Method for Geophysical Plastic Flows
We explore possible applications of the Lattice-Boltzmann Method for the simulation of geophysical flows. This fluid solver, while successful in other fields, is still rarely used for geotechnical applications. We show how the standard method can be modified to represent freesurface realization of mudflows, debris flows, and in general any plastic flow, through the implementation of a Bingham c...
