Flow patterns on the solar surface can provide insight into the dynamics of the solar convection zone and photosphere. Since basic properties of the solar fluid can be very difficult to observe directly, simulations of solar convection are necessary to explore the interplay between the solar fluid and surface features. We investigate flow dynamics on the surface of a convective fluid and discuss the relationship of the flow patterns to observable characteristics.
Passive floaters advected by the surface velocity field rapidly collect in the downflow lanes.
We identify this larger, longer-lived pattern with mesogranular flows. The relationship between the mesogranules and the surface distribution of magnetic features is discussed.
