Development of reducing technique of snow accumulation around the wake area of the central building at Syowa Station, Antarctica was researched, In the field survey, the relation between the mass of snow drift and the snow transport rate was linear. The results of the cold wind tunnel test were compared with the field survey at Syowa Station. The snow accumulation concentrated in the narrow space between the warehouse building and the sewage disposal plant building. The generation place of snow drift is predictable by the wind tunnel test used L.D.V. and the computational fluid dynamics. The method of adding some building parts on the original form to control wind flow with snow particles is not so effective. It is important that the space between buildings is expanded sufficiently to pass through blowing snow and snow particles in wind flow are transported in the lee of buildings.
