Local Climatological Study on Layout of Group of Storehouses in Tsushima Island, Japan

Abstract

The objective of this study is to verify the relationship between the layout of group of storehouses and the winter microclimate of the settlement in Tsushima Island, Japan. Climatic conditions were observed in Waniura settlement in winter of 2019. In the northern part of Waniura settlement, there is the largest group of storehouses in Tsushima Island, consisting of more than 150 storehouses. When adaptation to the windy environment was considered as a priority for the location of the group of storehouses, the southern part of the settlement and the east-west valley were found to be the most suitable sites, as they are upwind in winter and the wind velocity is not so strong. The reason why the group of storehouses was formed in the northern part of the settlement despite the area of strong wind was not only because it was upwind, but also because it was located halfway between the residential area and the cultivated land. It was found that the wind reducing effect appeared in the center of the group of storehouses and in the drying place called “Be-Doko” located on the south of the group of storehouses.
