INFLUENCE OF THE SOLAR-ACTIVITY ON FLUCTU ATIONS OF THE ATMOSPHERE ANGULAR-MOMENTUM, LENGTH OF THE DAY, AND COORDINATES OF THE EARTHS POLE

Investigations of the solar activity influence on fluctuations of the atmosphere angular momentum (AAM) and the length of the day (LOD) are continued using a wider statistical material (1976.0 - 1989.3) to whic h the data on variations of the Earth's pole coordinates (X, Y) are ad ded, The power spectra are computed via the fast Fourier transform tec hnique for seven time series: the Wolf numbers (W), solar radio emissi on flux at the wavelength 10.7 cm (R), geomagnetic index K(p), as well as AAM, LOD, X, and Y in the range from 20 days to approximately 7 ye ars. The periodicities found earlier are confirmed and new evidence of the solar activity influence on the considered geophysical phenomena is obtained.
