ABSTRACT
Problems in fluid dynamics are often far from the theoretician's ideal of homogeneous, isotropic systems. In this talk I shall describe the (relatively) new method of Direct Statistical Simulation where the statistical properties of the fluid are solved for directly (utilising an expansion in equal time cumulants), taking into account both inhomogeneity and anisotropy. I shall describe the formalism and algorithms before giving examples of the utility of the method for the model geophysical and astrophysical problem of the formation of jets in barotropic turbulence. Further extensions of the work will also be discussed.
