Keywords: wake vortex, atmosphere, aircraft configuration

Four-vortex systems shed by landing aircraft may decay quicker than the classical two-vortex wake. In this study we use the Large-Eddy Simulation technique to assess the impact of atmospheric turbulence on the decay characteristics of these vortex systems.
