Abstract

Strong winds frequently occur at Chiba Marine Stadium in Chiba Prefecture. Data analysis at Chiba AMeDAS station revealed that the strong winds during the warm season were caused by the intrusion from the southwest through the Tokyo Bay associated with extratropical cyclones passing to the north of the Kanto area or cold fronts. Field observation confirmed that wind variability at Chiba AMeDAS and the Makuhari area with the stadium showed good agreement in cases of south-southwesterly winds. Three-dimensional wind field in and around a doughnut-shaped building, imitating the Marine Stadium, was simulated by wind tunnel experiments. In the stadium, wind below was in the opposite direction of the general flows above the model, and there was a boundary between the flows with larger turbulence. The height of the boundary changed depending on the roughness on the windward side of the stadium and roof height facing the general flows. The occurrence of the reverse flows with the boundary between the general flows was confirmed by observation conducted in the Marine Stadium.
