WebMar 11, 2024 · Recent studies have indicated a correlation between Earth’s free core nutation (FCN) and geomagnetic jerks (GMJs). However, some uncertainties still need … WebMar 11, 2024 · There is still some remaining uncertainty [< 1 milliarcsecond (mas)] in the celestial pole motion in which the dominant signal is Earth’s free core nutation (FCN). Some nutation residuals and geophysical excitations also exist (Vondrák and Ron 2009 ).

WebFeb 7, 2015 · This oddball terms, along with the torque-free nutation, are collectively called polar motion. The motion is fairly smooth if one ignores nutation and polar motion, and the effects are all small. Precession, while very slow, can be quite large in magnitude. The rotational angular velocity vector that is used in determining the axial tilt ... WebThe Chandler wobble or free Eulerian nutation of the spin axis of the Earth in a body-fixed frame of reference was first discovered by Chandler (1891). A detailed theory of the Chandler wobble from a ‘normal-mode’ perspective was first presented by Dahlen and Smith (1975) and has been more fully developed since by Wahr (1982, 1983) whose ...
WebThe simulation of a free nutation process is presented by modeling it with a damping process and energy losses in the oscillation of a not so well-balanced spinning top. Vibration analysis often takes into account the energy losses by means of a single factor called the damping factor. The nutation model of the spinning top consists of a not so ...
