Abstract

The regularities of variations of the aerosol disperse composition in tropical and equatorial zones of Atlantic are analyzed on the basis of the spectral data on the aerosol optical thickness (AOT) of the atmosphere measured during the 35-th cruise of the research vessel “Academician Mstislav Keldysh”. The characteristic peculiarities are studied of the aerosol disperse composition at different distances from the continent, as well as at intrusion of air masses (AM) enriched with aerosols of continental origin to the region of observations. The estimates show that the distribution of coarse aerosol particles (r>1.0 μm) near continent inside an AM enriched with the dust component is essentially inhomogeneous. Quite fast transition from the disturbed values AOT to weakly disturbed (~ 5-8 hours) is evidence of the compact manner of their distribution inside the AM. As moving from the continent, the aerosol particle distribution gains more homogeneous smooth structure. The enhanced level of the content of large particles in the tropical trade wind zone remains in the atmosphere in the episodes when there are no extreme disturbances of AOT. This “background” from emissions from the continent is almost one order of magnitude greater than the background content of large particles in mid-latitudes.
