Effects of Mantle Anelasticity on the Chandler Wobble
View through CrossRef
On the basis of the perturbation principles of the normal mode and Love numbers, the theoretical Q of the Chandler wobble is derived by assuming that the wobble energy is totally dissipated within the mantle and by using Zschau's mantle rheology model. The results show that mantle anelasticity is likely to be the most important dissipative source of the Chandler wobble energy, and the theoretical Chandler Q is 71. Finally, the parameter α of the absorption band model is calculated, and the applicability of the model is discussed as well.
