| Abstract: | Summary. The Chandler wobble Q w, as obtained from the astronomical data cannot be equated with the Q m of the source of damping, as an examination of Chandler wobble energetics reveals. We find that if dissipation occurs in the mantle then Q w≃ 9 Q m, implying that either the mantle Q is frequency dependent or the wobble Q is much larger than 100. If the dissipation is in the oceans then Q w≃ 20 Q o, and the pole tide must be far from equilibrium. |
