The observed scale of granulation is derived as a consequence of a physical model. At scales smaller than granulation, horizontal radiative transport reduces temperature fluctuations and the resultant buoyancy forces in the surface layers. At scales only slightly larger than granulation, the dynamical pressure required to drive horizontal motions changes the opacity sufficiently to reduce the apparent contrast. This raises the possibility that the dark center of an exploding granule may actually be hot below the surface. The maximum possible horizontal extent of a surface-driven convective flow is estimated as 4.5 times granular scale.
