Variations of the Seasonal Inequalities and Irregular Fluctuations of UT2-TAI


Dragutin Djurović




UT2-TAI data, given every 5 days, for the period 1967.0-1978.0 will be treated here with the purpose of investigating to what extent the two components of the seasonal inequalities of the Earth's rotation (annual and semiannual) are subject to changes as well as to determine the epochs and amplitudes of the largest irregular fluctuations of the system of Universal Time UT2.
