Field Measurements of Winds on Atmospheric Corrosion for Important Cultural properties

Abstract

Field measurements of winds on atmospheric corrosion for two important cultural properties were carried out.
First, observations of a Buddhist statue were made. In the area where the statue is located, winds blow from the south or north most frequently. On rainy days, winds blow mostly from the north and during strong winds, winds are in most eases from the south. Due to this, it was presumed that northerly winds would cause pollutants and that southerly winds would bring salt particles from the sea to the Buddhist statue.
Second, observations were made of a shrine as another important cultural property. Metallic parts of the shrine building corrode due to damage from salt. Although an analysis which is directly related to atmospheric corrosion has yet to he carried out, it was found that strong winds blow mainly from the sea in this area. Furthermore, the wind direction characteristics caused by the topographic features along the Sea of Japan in Shimane Prefecture were investigated by carrying out analyses of winds which include data obtained at several meteorological offices.
