Field observations of sea-salt quantity transported landward by winter monsoon

Field observations of sea-salt quantity transported by winter monsoon have been performed on a reclaimed land facing Japan Sea. The landward transported sea-salt quantity and the deposit rate have been estimated quantitatively and the leeward profiles have been normalized by introducing representative scales. Especially, the normalization gives us a universal expression for the deposit rates by winter monsoon and Typhoon 9117. The transported sea-salt quantity decreases rapidly in the dimensionless distance less than 25 because of the settling of sea-salt particles. The representative scales introduced for the normalization depend strongly on the mean wind velocity at the height of 10m. The empirical expression for the deposit rates and the quantification of the representative scale enable us to predict the settling flux of sea-salt at an arbitrary place in the coastal area.
