Multidecadal fluctuations in Earth’s length of day are shown to be driven by gravitational torque and resisted by electromagnetic and topographic forces, improving our understanding of the material properties and dynamics of Earth’s deep interior.
Torque and changes in the LOD
An axial torque z acting on the mantle causes a change in its rotation rate (m) according to
$${C}_{{\rm{m}}}\frac{{\rm{d}}\Delta {\varOmega }_{{\rm{m}}}}{{\rm{d}}t}=… [+20273 chars]
