In this presentation we explore tracer advection in the context of weakly compressible flows arising in anelastic fluids.
To do this we exploit the hybrid discontinuous Galerkin (HDG) method via the GeoPart and LEoPart libraries in conjunction with the 
FEniCS project.
We present some esoteric findings and aesthetic images.
