Abstract

In this paper the impact of the Solar magnetic field on ⁷Be activity concentration in aerosols was investigated. The changes in the ⁷Be activity in aerosols in the period from the second part of 22nd to the second part of 24th Solar cycle were mathematically processed using the Fourier analysis and the 22 years period was pointed out. It corresponds to the most intense period of the Solar polar field strength for the same observed period. The Pearson's linear coefficient between the average annual value of ⁷Be activity in aerosols and the Solar polar field strength was 0.58.

Keywords: (7)Be activity; Fourier analysis; Solar magnetic field.
