Fig. 9

Sketch of the magnetic and velocity field configuration in a light bridge granule. The solar surface is indicated by the thick green line. The upflowing material in the nearly field-free cell interior is depicted by the blue parts of the curved arrows. The downflowing material (red lines) is able to drag down magnetic field lines (black and purple), creating a region where additional heating might occur (yellow crinkled line). The background colors in the cell interior indicate the LOS velocities (upflows: blue, downflows: red/yellow).
