An analysis is made of the velocity field determined from spectral absorption line profiles as well as inhomogeneous element sizes obtained from stochastic theory. The results of three-dimensional simulations of convective motions in the photospheres of the Sun and Procyon are presented. It is concluded that penetrative convection covers a considerable fraction of the Procyon photosphere.
