Still image from supergranular evolution movie. Top row: simulated cork density (run #5) and observed line-of-sight magnetic field for the average supergranular outflow, as shown in Figs. 10 and 9. Bottom row: maximum and minimum cork density and magnetic field strength as in Fig. 11. In addition, the highest absolute value at the current time is marked with the black circle. The full temporal evolution for both, the inflow and the outflow, can be found in the two movies attached to this figure.
