TURW03 - Modelling and analysis of turbulent transport, mixing and scaling

In this talk, I will cover some of the key geometric aspects of geophysical turbulence that underpins both our pragmatic approaches (in parameterizing and developing subgrid schemes) and our diagnostic approaches (using advected passive tracers to better understand these actions of turbulence).  I will highlight the different scales, energization, and symmetries of mesoscale (10-100km), submesoscale baroclinic (1-10km), submesoscale symmetric (10m-1km), and boundary layer instabilities and how these confer aspects to the turbulent transport by the finite amplitude consequences of these instabilities.  I will discuss some of the diagnostic challenges associated with modeling and observing these heterogeneous, nonstationary, and anisotropic phenomena.
