Chandler wobble calculation
WebFor the Earth, this Eulerian free wobble is known as the Chandler wobble in honor of S.C. Chandler who first observed it in 1891 [Chandler, 1891]. From observations of the … WebMay 18, 2015 · 1 Introduction. The free Chandler wobble has the largest amplitude of any of the oscillations in the observed polar motion. In contrast to the forced wobbles, whose periods are the same as the periods of the geophysical forcing mechanisms, the period and quality factor Q of the Chandler wobble depend on the distribution of surficial fluids and …

As long as the laser is not exactly at the equator, the axis of the light's rotation will have some overlap with the ... WebNov 24, 2024 · Chandler himself demonstrated that the wobble in fact consists of two combined motions, one with a period of 427 days, the other with a roughly annual period. This indicated that the amplitude of the wobble would become larger or smaller over a period of seven years, depending on whether the two components of the wobble were …
WebMar 1, 2009 · The calculations of the Chandler wobble period T W have been performed for a set of interior structure models of Mars with 50- and 100-km thick crust and averaged crustal density varying in the range 2700–3200 kg/m 3.The models satisfy new values for the moment of inertia and the elastic tidal Love number k 2 s.The observational data … WebChandler angular frequency is 0 = c + i 2, (3) where is the damping time. The damping time is given by = 2Q/ c with c the real Chandler angular frequency. In the absence of excitation, the free wobble is m(t) = Cei 0t, (4) with C a complex constant. The free polar motion is then pro-grade along a circular spiral at the Chandler angular frequency c,
