  Information - NP6.01 Transport, Diffusion and Mixing in Geophysical flows

Event Information
The structure of a fluid flow and of the fields of contaminants, chemicals, temperature, moisture and other scalars or particles that it may carry can have a determining effect on various physical properties such as mixing, dissipation, flux and transfer of various quantities. The session will address the theory, observations and measurements in geophysical and environmental flows and turbulence: these include fractal and multifractal measures, wavelet analysis, structure functions, Lyapunov exponents and multi-particle statistics. The relations of these measurements to the kinematics and dynamics of mixing, flux and transfer will be discussed involving geometrical observations and physical relations used to develop predictive schemes in geophysical and environmental flows involving turbulence.
This Session will be devoted to mixing and transport of tracers (passive, chemically or biologically active, or dynamically active) in geophysical flows (in atmosphere, ocean, or Earth's interior). The aim is to bring together contributions from theoreticians and experimentalists involved in geophysical model development and data analysis, as well as from researchers in dynamical systems theory, stochastic modelling, and related fields, to stimulate cross-fertilization.
