Granulation and supergranulation as a diagnostic test of solar structure
Abstract
Current knowledge of solar structure is applied to the evaluation of theoretical models of convective energy transport in stellar or solar regions with superadiabatic temperature gradients. Techniques are developed to test the accuracy of mixing-length models and their nonlocal extensions on the basis of observational data on supergranulation and granulation in the outer layers of the sun. Supergranulation is found to play only a minor role in energy transport. It is predicted that the smaller upper-layer temperature gradients of nonlocal theories can strongly influence granule flux modulation.
