We study the development of convective structures in the solar photosphere on the basis of the photospheric convection models obtained using data from VTT by the solving of the inverse nonequilibrium radiative transfer problem. Temporal changes of the variations of vertical velocity and temperature within granular cells are analyzed. Features of the appearance and the disappearance of granules according to their size, the formation of “trees” of fragmenting granules are investigated.

Photosphere convection, granular cells, fragmentation.
