This paper presents intensity evolution of finite energy Airy Hermite Gaussian(FEAHG) beam and its scintillation performance under strong atmospheric conditions. Atmosphere is modeled utilizing split step propagation. Our results reveals that, beam evolves into elliptic shape during propagation. Point like scintillation reduction is obtained for all setting of FEAHG beam. For selected apertures less scintillation index is provided by FEAHG beam. We think that our results are used in free space optical communication systems.
