Based on the extended Huygens-Fresnel principle, the propagation of the elegant vortex Hermite-Gaussian (vHG) beam through the atmospheric turbulence is analyzed numerically. The intensity of the vortex beam will changes from the hollow distribution to the Gauss distribution with the increase of the turbulent atmosphere or transmission distance. The topological charge, beam size and wavelength all are associated with that process. The result obtained is similar with the propagation of the Laguerre-Gaussian beam in turbulent atmosphere. Finally, the beam spreading of the elegant vHG beam traveling through the atmospheric turbulence is considered. The influence of the beam parameters (topological charge, beam waist radius and wavelength), transmission distance and atmospheric turbulence on the beam spreading of the elegant vHG beam is explored in detail. The results have great potential applied values for the free space communication.
