SUMMARY:Strong Field Dynamos in Rapidly Rotating Convection with no Inertia
  - David Hughes (University of Leeds)
DESCRIPTION:David Hughes (University of Leeds)
Résumé
It is generally bel
 ieved that the magnetic field generated by dynamo action in rapidly rotati
 ng bodies\, such as the Earth\, is strong ? in the sense that there are si
 gnificant differences between the hydrodynamic convective state and the co
 nvection once dynamo action sets in. That said\, obtaining strong field so
 lutions numerically has proved to be extremely difficult. Most computation
 al dynamo solutions only generate a weak field\, with the convection being
  influenced only slightly by the generated magnetic field. One of the prob
 lems seems to be that the solutions are still dominated by inertia\, where
 as in the Earth\, for example\, inertia is believed to be negligible. Thus
 \, to try to access the strong field solutions we here neglect the inertia
 l terms from the outset\, which of course has both physical and mathematic
 al consequences. However\, as we shall see\, it does allow an exploration 
 of both weak and strong field solutions and their underlying physics.
