The relationship between airborne salt and velocity and direction of wind in Niigata

Eiji IWASAKI, Masatugu NAGAI

Weathering steel is known as a type of steel that is affected by Airborne Salt Amount. In the previous studies, the relationship between the amount of airborne salt and velocity of wind has demonstrated at position of 1 kilometer from the seashore. But, it is necessary to survey the relationship between airborne salt amount and velocity of wind at position of 20 kilometers from the seashore because measurement of airborne salt is required to weathering steel using in Niigata prefecture.
In this study, I carried out following procedures. First, I looked up the relationship between airborne salt amount and velocity and direction of wind. Secondly, I calculated the contributing rate of airborne salt amount in every direction of wind. As the results, I predicted an airborne salt amount in next year.
