The thermal self-action of partially coherent beams in a moving medium is described based on the radiation transfer equation. The solution of this equation in the ray approximation permits reducing the problem of the self-action to the solution of a system of ordinary differential equations. Differences in the self-action of coherent and partially coherent beams are discussed. Calculations of the coherence radius over the beam cross section are presented. It is shown on the basis of this approach that in the geometric-optics approximation the coherence factor is invariant along any geometric ray.
