Turbulent compressible convection with rotation

Abstract

We examine the effect of rotation on turbulent compressible penetrating convection, motivated by the dynamics of the solar interior. We find that rotation can influence large-scale coherent structures in the turbulent flow whilst leaving the small-scales isotropic. The dynamics in this case are very different from more laminar situations where all scales are rotationally- influenced. This may hint as to why full models of the global solar differential rotation are difficult. © 2007 International Astronomical Union.
