Description:
From the various presently discussed coupling mechanisms of core and mantle the topographic coupling along the core-mantle boundary (CMB) is considered in detail. A new estimation of this coupling is given which is based on exact asymptotic analysis of corresponding hydrodynamical equations. It is shown that for the model without dissipation, topographic coupling between the core and mantle is probably much larger than previously estimated. Effects of vortical flow dissipation are considered. © 1993, Society of Geomagnetism and Earth, Planetary and Space Sciences. All rights reserved.
