In order to study the influence of wind directions on the flow field structures of deck, numerical simulation method was used to solve the air flow field on the upper deck of the ship. Streamline pattern and vorticity distribution of the flow field with different wind directions were analyzed. The vortices in the flow field were classified, and the causes, evolutions and mutual effects of different vortices were elaborated. Results show that the front part of the flow field, with wind from 0° direction, is influenced by the bow separation vortex, and the superstructure shedding vortex influence a small area of rear deck behind the superstructures. The flow field, with wind from starboard 15° direction, is mainly influenced by the right upwash vortex and the superstructure shedding vortex. The flow field, with wind from larboard 15° direction, is mainly influenced by the left upwash vortex.
