An 11.5 years time series of Earth rotation parameters is analysed with respect to variable periods and amplitudes of the principal frequencies. Tremendous variations are found in the period of the Chandler wobble. The bearing of these variations upon the predictability of Earth rotation parameters is estimated. Finally, the correlation between Earth rotation parameters and atmospheric angular momentum parameters is discussed.
