<p>This paper explores the properties of a partially coherent modified anomalous vortex beam (PCMAVB) in maritime turbulence. The propagation formula of the PCMAVB through the considered turbulence media has been derived using the extended Huygens-Fresnel integral. Numerical examples are provided to examine how maritime turbulence strength influences the intensity distribution under various initial beam parameter conditions. The results reveal that the PCMAVB maintains its initial profile over short distances; however, with further propagation, the beam gradually loses its properties, evolving into a Gaussian beam in the far field. The rate of increase in the central peak intensity accelerates as the turbulence’s constant structure rises and the turbulence’s inner scale size diminishes, or as beam parameters such as coherence length and topological charge are reduced. Moreover, lower values of the modification parameter <i>δ</i> improve the beam’s resistance to turbulence at short distances. This suggests that the modification parameter introduces a new aspect for controlling the properties of hollow beams. The obtained results may prove useful for practical applications of PCMAVB in free-space optical communications.</p>
