Abstract
Atmospheric environment and related thermal comfort on beaches in summer are significant factors for coastal space design to provide desirable amenity environments. Through a micrometeorological field observation conducted in summer on Makuhari Beach facing Tokyo Bay, we found that;(1) an internal boundary layer of see breeze was clearly formed on the beach, (2) the beach surface with dry sand has appreciable effects of heating and drying on the surrounding air body, and (3) three physical comfort indices DI, SET* and HS calculated with the observed data show that the sandy beach and its surroundings provide a highly contrasted spatial structure in thermal comfort.
