Abstract

We compare our results about the variation of the vertical and horizontal velocity with height in the Solar photosphere with the theoretical granulation model by Nelson. The comparison shows, (i) that the mixing length derived by Nelson corresponds to the height of the overshoot-layers derived by Nesis, and (ii) that the large spatial structures with large horizontal velocities dominate the continuum layers.
