28. Sunspot moats versus supergranules

Contributed by Michal Švanda. Posted on September 24, 2014

Flow system in an average supergranule is compared to the moat flow around axisymmetric sunspots. Both phenomena are very similar, only the outflow in the moat is distorted due to the proper motion of the sunspot with respect to the local frame of rest and moat is a purely downflow region.
