Resource Letter TF-1: Turbulence in Fluids
This Resource Letter provides a guide to the literature on fully developed
turbulence in fluids. It is restricted to mechanically driven turbulence in an
incompressible fluid described by the Navier-Stokes equations of hydrodynamics,
and places greatest emphasis on fundamental physical questions. Journal
articles and books are cited for the following topics: The Navier-Stokes
equations, qualitative aspects of turbulence, the 1941 Kolmogorov theory,
intermittency and small scale structure, time correlations and pressure; with
brief mention of two-dimensional turbulence, passive scalars in turbulence, and
the turbulent boundary layer,Comment: 38 pages LaTeX, no figures. To appear in American Journal of Physic
Recent Developments in Understanding Two-dimensional Turbulence and the Nastrom-Gage Spectrum
Two-dimensional turbulence appears to be a more formidable problem than
three-dimensional turbulence despite the numerical advantage of working with
one less dimension. In the present paper we review recent numerical
investigations of the phenomenology of two-dimensional turbulence as well as
recent theoretical breakthroughs by various leading researchers. We also review
efforts to reconcile the observed energy spectrum of the atmosphere (the
spectrum) with the predictions of two-dimensional turbulence and
quasi-geostrophic turbulence.Comment: Invited review; accepted by J. Low Temp. Phys.; Proceedings for

Ergodicity of Two Dimensional Turbulence
We review the work of Hairer and Mattingly on ergodicity of two dimensional
Navier-Stokes dynamics and discuss some open mathematical problems in the
theory of 2d turbulence.Comment: Bourbaki lectur
