Abstract: The length of day series during the period of 1962.0 - 2000.0, the atmospheric angular momentum and the Southern Oscillation Index are adopted to analyze the relationships among the ENSO events that have occurred since 1960, the changes in the length of day and the atmospheric angular momentum. Attention is particularly given to the different effects of the 1982-1983 and 1997-1998 ENSO events on the variations of Earth rotation. The synthetic excitation effects of multi-scale atmospheric oscillations on the anomalous variations of the interannual rates of Earth rotation are revealed by means of the time-frequency spectrum of the wavelet transform.
