In this work, we theoretically proposed a model of vortex beams transmitting in a merged atmospheric turbulence and aerosol medium, which based on the extended Huygens-Fresnel diffraction principle. Fourier transform (FT) method augmented with subharmonics and correlation function method were used to produce turbulence phase screens and aerosol phase screens, respectively. Simulation results show that the phase distortion caused by aerosol scattering significantly affects the OAM spectrum of vortex beams. The stability of vortex beams falls with the rises of topological charge (TC) number in merged medium.
