For realistic stellar atmospheres the equations describing mesoturbulent line formation are solved numerically. The general dependence of theoretical line profiles and equivalent widths on the correlation length 1 and the mean square turbulent velocity a is demonstrated. Also empirical relations between the basic parameters of the micro-macroturbulence description (vmic, vmac) and the fundamental mesoturbulence parameters (1,σ) are derived.
