Dynamical model of solar granulation

We contruct a steady-state model of solar granulation with a simplified horizontal structure. As in our previous model the transfer of radiation dominates the energy balance and determines the temperature fluctuations. The turbulent drag force which we include in a simplified form balances the buoyancy created by the temperature fluctuations. Penetration of velocity and temperature fluctuations are similar to those observed.The small-scale turbulence generated by granular motions may be an important contributor to observed unresolved motions but cannot account for the total
