In this paper we consider a closed numerical model of thermal blooming of the single–mode, partially coherent radiation propagating under conditions of self–induced convection. Study of compensations for the laser beam phase distortions is carried out using optical modes of the first, second, and third orders. Efficiency of compensation is estimated by a spectral criterion characterizing angular divergence of the beam at the cell exit.
