Abstract

Airborne chlorides is known as the deterioration external force of superstructure(an structure that is not directly contacting seawater) and is used as a boundary condition of the structure degradation prediction model so that it is necessary to estimate the correct value of airborne chlorides. However, it is difficult to quantify airborne chloride because it has various distribution and flow characteristics by surrounding weather conditions. In order to investigate the possibility of quantification of airborne chloride by using weather data, this study intends to carry out correlation analysis between the actual airborne chloride measured at actual marine environment and the weather data recorded or observed at monthly weather report, AWS(Automatic Weather Station) and anemovane. Results revealed a frequency of wind at the whole wind speed range(0<$$W(m/s){\leq_-}20$$) observed through the anemovane has the highest correlation with an average wind speed at the whole wind speed range(0<$$W(m/s){\leq_-}20$$) observed through AWS, as compared with other conditions. These results will be helpful to increase the possibility of quantifying the airborne chloride. In addition, a seasonal correlation analysis of airborne chloride and weather conditions shows the winter season has the highest correlation for them, compared to other season. Therefore, wind generated in winter has a very dominant effect on the distribution and flow of airborne chloride.
