As arguments in favour of the notion that very slow convection in the highly viscous mantle is confined to the upper 700 km gradually weakened over the past 20 years, so geophysicists have increased their willingness to entertain the idea that significant horizontal variations in temperature and other structural parameters occur at all levels in the lower mantle. Concomitant density variations, including those caused by distortions in the shape of the core-mantle interface, would contribute… 
Topographic Core-Mantle Coupling and Fluctuations in the Earth's Rotation
Astronomically-determined irregular fluctuations in the Earth's rotation vector on decadal time scales can be used to estimate the fluctuating torque on the lower surface of the Earth's mantle
The core-mantle boundary region
The 75 year history of the American Geophysical Union has accompanied great advances in our understanding of the physics and chemistry of the transition zone between the Earth's core and mantle. The
Topographic core-mantle coupling and polar motion on decadal time-scales
SUMMARY Associated with non-steady magnetohydrodynamic (MHD) flow in the liquid metallic core of the Earth, with typical relative speeds of a fraction of a millimetre per second, are fluctuations in
Effects of a heterogeneous mantle on the Velocity and Magnetic Fields at the Top of the Core
SUMMARY Magnetic induction due to a steady flow of the core past a bumpy, heterogeneous mantle is investigated numerically. This study emphasizes short-wavelength phenomena so that a Cartesian
Core-mantle topographic torque: a spherical harmonic approach and implications for the excitation of the Earth's rotation by core motions
Abstract The interaction of the fluid pressure over the topography of the core mantle boundary generates a torque that leads to perturbations in the Earth's rotation. A general formulation of this
Fluid flow near the surface of Earth's outer core
Maps of the fluid flow at the core surface are important for a number of reasons: foremost they may provide some insight into the workings of the geodynamo and may place useful constraints on
Electromagnetic and topographic coupling, and LOD variations
The role played by di erent core processes in the changes in the Earth's rotation is assessed and fully dynamical models of the torsional Alfvén waves inside the uid core are reviewed. These waves,
Core-mantle boundary shape: constraints inferred from the pressure torque acting between the core and the mantle
SUMMARY In the last few years, models of the flow at the top of the Earth's core and of the related pressure field have been calculated from the secular variation of the geomagnetic field, and
Geomagnetism, Earth rotation and the electrical conductivity of the lower mantle
Abstract A new approximation is derived for the electromagnetic torque acting on an electrically conducting mantle as a result of fluid flow in the core. The torque considered is that associated with
Core–Mantle Interactions
Interactions between the core and the mantle arise when heat, mass, momentum, or charge is transferred across the core–mantle boundary (CMB). Each of these interactions has consequences for the

Evidence for the presence of undulations or temperature variations, or both, at the core-mantle boundary comes from the remarkably high correlation between the pattern of long-wavelength
Westward drift, core motions and exchanges of angular momentum between core and mantle
The westward drift is one of the most well known features of the geomagnetic field. In this paper we come back to the apparent drift of the main field as seen at the Earth's surface, and show that
Interaction between the Earth's Liquid Core and Solid Mantle
HORIZONTAL stresses at the interface where the liquid core of the Earth meets the surrounding solid mantle prevent these two major regions of the Earth from moving independently of one another.
Summary. Previous studies, both geomagnetic and seismic, have been unable to show conclusively whether or not there is fluid upwelling at the core-mantle boundary. Here a new method is developed, in
On the excitation of short-term variations in the length of the day and polar motion
Variations in the distribution of mass within the atmosphere, and changes in the pattern of winds produce fluctuations in all three components of the angular momentum of the atmosphere on time-scales
On the effects of a bumpy core-mantle interface
Abstract Motivated by the high degree of correlation between the variable parts of the magnetic and gravitational potentials of the Earth discovered by Hide and Malin (using a harmonic analysis
The westward drift of the Earth's magnetic field
The westward drift of the non-dipole part of the earth’s magnetic field and of its secular variation is investigated for the period 1907-45 and the uncertainty of the results discussed. It is found
Thermal core– mantle interactions
Maps of the magnetic field at the core–mantle boundary for 1715–1980 reveal static features in the field and an absence of westward drift from much of the core–mantle boundary. The static features
Time Variations of the Earth's Magnetic Field: From Daily to Secular
Variations in time of the Earth's natural magnetic field have a frightfully wide spectrum, ranging over more than 20 orders of magnitude: They extend from well over 103 Hz, where they merge into the
Electromagnetic Core-Mantle Coupling
The time-scale of the variation in the length of the day is comparable to, or shorter than, the electromagnetic decay time, τη, of the mantle. This suggests that an electromagnetic theory for the
