A magneto-hydrodynamic model of boundary layers at the Core -Mantle Boundary (CMB) is derived and used to compute the viscous and electromagnet ic torques generated by the Earth’s nutation forcing. The predicted electromagnetic t orque alone cannot account for the dissipation estimated from the observations of the free cor nutation. The presence of a viscous boundary layer in the electromagnetic skin layer a t the CMB, with its additional dissipative torques, may explain the geodetic data. An… CONTINUE READING
