Using coherence theory, the partially coherent flat-topped vortex hollow beam is introduced. The analyticalequation for propagation of a partially coherent flat-topped vortex hollow beam in turbulent atmosphereis derived, using the extended Huygens-Fresnel diffraction integral formula. The influence of coherencelength, beam order N, topological charge M, and structure constant of the turbulent atmosphere on theaverage intensity of this beam propagating in turbulent atmosphere are analyzed using numerical examples.
