The work of the International Polar Motion Service which aims at the study of polar motion has progressed smoothly from its beginning at 1962.0 with the collaboration of more than 50 stations in 24 countries — Algeria, Argentina, Australia, Belgium, Brazil, Canada, Chile, China, Czechoslovakia, Equador, Finland, France, Germany, Italy, Japan, Poland ...

Tectonophysics, 1972
Abstract Problems about the origin of polar motions and earth tides, and the accuracies reached in their determination, are discussed. The common references system (C.I.O.) for the measurement of the instantaneous pole of rotation is defined. Hypotheses for the origin of the Chandler wobble are critically reviewed. The importance of the seventy years

On the Damping Coefficient of the Polar Motion
Publications of the Astronomical Society of Japan, 1966Abstract The theory of the excitation and damping of the polar motion is developed for stationary excitation functions, and sufficient conditions for the excitation function are investigated. The relation between autocorrelation functions of the polar motion and the excitation function, μq(s) and μQ(s) is found to be μ q s

On the Excitation and Damping of the Polar Motion
Publications of the Astronomical Society of Japan, 1965Abstract In the present paper, the excitation and damping of the polar motion are treated as a series of stochastic process, and the damping coefficient and constants concerning to the excitation of the polar motion are determined. The damping .coefficient thus determined is 0.320 (year–1), which is very close to that obtained by WALKER ...

Polarization, conformal invariants, and Brownian motion
1998For a set \(A\) in the complex plane, let \(A_+=A\cap \{z:\text{Im} z\geq 0\}\), let \(A_-=A\cap \{z:\text{Im} z\leq 0\}\), and let \(\overline A=\{\overline z:z\in A\}\). If \(A\) is either an open set or a closed set, define the polarization of \(A\) by \(P(A)= (A\cup \overline A)\cup (A \cap \overline A)\).

The Influence of Earthquakes on the Polar Motion
1986The high accuracy of the recent polar data obtained by space technics, and the availability of the seismic moment tensors of the strong and moderate earthquakes, make it possible to investigate with an increased confidence the influence of earthquakes on the excitation of the Chandler wobble. The comparison of the observed Chandler wobble for 1977–1983,
