Abstract

Synchronous measurements of a scattering value at change of wind speed on an open sea surface show that with to wind speed growth there is an increase in salt aerosol concentration. At the same time, in coastal conditions the opposite effect is observed, at increase (decrease) of wind speed there is decrease (increase) in aerosol extinction in the sea and coastal atmosphere surface layer. It means that change of the scattering value can be described (ignoring effects of the second order at high wind speeds) by a source modulated in the changing wind speed. In the article as such source it is offered to use the parameter fetch. It is shown, that at small fetch (coastal conditions) at increase in wind speed there is a decrease of aerosol extinction α(λ) in all spectral wavelength band, and at big fetch (open water) with growth of wind speed occurs increase α(λ) on all wavelength.
