A possibility of estimating beam perturbations due to gravitational convection and transverse air blow from the thermal blooming effect is demonstrated in this paper for optical beams of variable radii propagating along a model laboratory path. Perturbations of focused and self–focused beams occurring on the propagation path are proposed to be estimated based on the value of their mean radii, for which we have derived approximate analytical relationships.
