Spectral characteristics of geomagnetical fields of tashkent geodynamical test ground

摘要

Materials of current watching over the variations of components of geomagnetical fields for half a century period have been analysed. The main features of aged variations were described. Spectral consistings show clearly expressed tops with the periods of 40 and 11 years: 12 months: 28 days and 24 hours. The natures of these consistings are in discussions now. The filtered rest of the outpointed components demonstrate much correlation with the seismieness of the region.
