A new phenomenon, the generation and evolution of the optical vortices, in the domain of light propagation in the turbulent atmosphere, has been investigated recently. The optical vortex has potential and serious impacts on the electro-optical engineering, and it also could provide new mechanism for possible applications. Development on study of optical vortex propagation in the atmospheric turbulence was summarized.Optical properties and topological characteristics of the optical vortex were introduced from the point of view of phase singularity. The propagation dynamical characteristics of some optical vortices and their combination in a linear and a non-linear media were shown with numerically- simulated results. The generation and development of the optical vortex in the atmosphere and topological charge transmission problem in the atmosphere were discussed. And the impact of the optical vortex on the phase compensation technique for light propagation in the atmosphere was analyzed. Finally, some potential applications of the optical vortex were proposed in consideration of their propagation dynamics.
