in which the complex-valued function It=I13t+iI23t where I13 and I23 are the perturbations of the inertia tensor associated with the variations in the mass distributions in the atmosphere and the oceans that may be responsible for wobble excitation. The function ht=h1t+ih2t represents changes...
We have PCWrigid≈965 year (Rambaux and Bois, 2004) for C = 0.34M R2 and the Mariner 10 values of J2 and C22 (Anderson et al., 1987). With a large fluid core with moment of inertia half of that of the total planet moment of inertia, the Chandler wobble period is half the ...
carry angular momentum and may induce a polar motion throughh(t). Processes that redistribute mass on Earth’s surface or in the interior, such as ice melting, groundwater depletion, sea-level rise and solid Earth deformation, induce a polar motion through a perturbation of the inertia tensor...
and the geoid have become available (e.g. Kaula 1966).According to Goldreich & Toomre (1969) the inertial moment of the Earth may be separated into a hydro- static part due to the equilibrium bulge under rotation and a non-hydrostatic part due the topical distribution of mass anom- alies...
