WebThe magnetostrophic approximation is an alternative approach that neglects viscous effects altogether ( E=0) in the interior of the core. A consequence of this is Taylor's constraint [Taylor, J.B., 1963. The magnetohydrodynamics of a rotating fluid and the Earth's dynamo problem. Proc. R. Soc. London, Ser. A 274, 274-283]. WebAug 15, 2008 · It is well known that in the magnetostrophic limit, the geostrophic component of the flow must adjust to ensure Taylor's constraint [Taylor, 1964]. A modification of the non-geostrophic flow similar to the one envisioned here could in principle rapidly alter the zonal shear on which the instability itself relies.
