New Determination of the “Decade” Fluctuations in the Rotation of the Earth 1860–1978
Observations of the Earth–s rotation have shown irregular variations of rate which have characteristic times of decades. These have been attributed to transfer of angular momentum between core and mantle by some mechanism such as inertial coupling, viscous stress, electromagnetic coupling or stresses produced by topographic features on the core mantle boundary.
