Analyses of Lunar Laser ranges Shaw a displacement in direction of the Moon's pole of rotation which indicates that strong dissipation is acting on the rotation.
Non-steady differential rotation is one of the main characteristics of the buoyancy-driven flow within the Earth's liquid metallic outer core that generates the main geomagnetic field by magnetohydrodynamic (MHD) dynamo action. Concomitant fluctuations in angular momentum transfer both within the core and between the core and the overlying 'solid' mantle are investigated by assuming that average departures from `isorotation' on coaxial cylindrical surfaces are negligibly small.

The impact of the 1997-1998 ENSO event is presented in context of Earth-atmosphere angular momentum exchange utilizing length of day (LOD), Southern Oscillation Index (SOI) and atmospheric angular momentum (AAM) data from 1970 to 1998; comparisons are made with previous events.
The oceans have a major impact on global geophysical processes of the Earth.
Both surface and internal mass redistribution causes geocenter variations. The global surface mass redistribution can be measured or modeled and is considered as the primary contributor to the geocenter variations on seasonal time scale.

The geocenter variations reflect the global scale mass redistribution and the interaction between the solid Earth and the mass load.
