Earth's rotation variations: a wavelet analysis
Description: Historical to up-to-date data of the minute variations in the solid Earth's rotation are subjected to a comprehensive time-frequency wavelet analysis. The length-of-day for the period 1962-2012 confirms the presence of a prominent, robust 6-year periodicity and reveals an anomalously strong 18.6-year tidal oscillation as well as a ~13-year quasi-periodic signal.
