台風時における海岸での海塩粒子濃度分布について

Abstract

Estimation of the distribution of sea-salt number concentration near the coast was carried out.As to the production rate, and the number concentration of sea-salt particles on the sea surface, new expressions by lida at als. (1992) , by way of a non-dimensional pa‐rameter including the wind stress and the spectral peak frecuency of wind waves, was applied. The vertical distribution of sea-salt particles was influenced by the distances where wind flew on the sea surface and sea-salt particles were produced.The variation of the estimated vertical distribution of number concentration of sea-salt particles with the typhoon 9119 can explain well with the distribution of salt damaged with passage of the areas as seen in the conditions of the orange trees at Nakajima Islands in the Seto Island Sea and electric supply facilities in Chugoku district.
