Abstract: A relationship between the distribution of aerosols and the tropical circulation under the different tropical circulation conditions during the TOGA experiment form 1985—1987 were studied. The concentration of aerosols has a value 10 μg/m3 or less in the tropical convergence zone due to the rain washout, and its distribution is independent on wind velocity. But, the concentration value under the rainless region in one order of magnitude larger than that under the rainfall zone. The distribution of the aerosols is inhomogeneous in the hurricane circulation. The lower value (100μg/m3) in the dry zone.
