Core Eigenmodes and their Impact on the Earth’s Rotation [PDF]
Surveys in Geophysics, 2021 AbstractChanges in the Earth’s rotation are deeply connected to fluid dynamical processes in the outer core. This connection can be explored by studying the associated Earth eigenmodes with periods ranging from nearly diurnal to multi-decadal. It is essential to understand how the rotational and fluid core eigenmodes mutually interact, as well as their

Earth's Rotation and Solar Activity [PDF]
Geophysical Journal International, 1989 Summary The 11-yr signal in the variation of length of day has been successfully identified and significantly linked to solar activity. A physical mechanism involving meteorological and oceanic variation is proposed.

Commission 19: ROTATION OF THE EARTH [PDF]
Proceedings of the International Astronomical Union, 2008 The IAU Commission 19 meeting during the XXVII IAU General Assembly in Rio de Janeiro was held on Wednesday 5 August 2009, sessions 3 (14:00–15:30) and 4 (16:00–17:30). It was attended by about 40 participants. The meeting was split into three sessions.

The climate of a retrograde rotating earth [PDF]
Earth System Dynamics, 2018 Abstract. To enhance the understanding of our Earth system numerical experiments are performed contrasting a retrograde and prograde rotating Earth using the Max Planck Institute Earth System Model. The experiments show that the sense of rotation has relatively little impact on the globally and zonally averaged energy budgets, but leads to large shifts

The Rotation of the Earth [PDF]
Monthly Notices of the Royal Astronomical Society, 1926 The three fundamental units in physics, which form the basis of the c.g.s. system, are the centimetre, the unit of length; the gram, the unit of mass; and the second, the unit of time. Material standards of length and mass are provided by the International Prototype Metre and Kilogram, preserved at the International Bureau of Weights and Measures at ...

On the Annual Earth’s Rotation [PDF]
International Astronomical Union Colloquium, 1980 AbstractA number of works have presented evidence that the seasonal terms of the Earth’s rotation are variables from year to year. In this paper, introducing a parameter associated to a mean seasonal kinetic energy we show evidence of about 4 year and 7 yr periodicity. This result is briefly discussed.

Dynamics of rotation of super-Earths [PDF]
Celestial Mechanics and Dynamical Astronomy, 2013 We numerically investigate the dynamics of rotation of several close-in terrestrial exoplanet candidates. In our model, the rotation of the planet is disturbed by the torque of the central star due to the asymmetric equilibrium figure of the planet. We model the shape of the planet by a Jeans spheroid.

Mountain building and earth rotation [PDF]
Geophysical Journal International, 1994 SUMMARY Whereas the present-day true polar wander and the secular non-tidal acceleration of the Earth have usually been attributed to postglacial rebound, it has recently been suggested that non-glacially induced vertical tectonic movements taking place under non-isostatic conditions can also be effective in changing the Earth's rotation. We present
