SUMMARY:Reflections on the Geodynamo - Peter Davidson\, Department of Engi
 neering\, University of Cambridge
DTSTART:20211126T160000Z

CONTACT:Prof. Jerome Neufeld
DESCRIPTION:Numerical simulations of the geodynamo are\, perhaps\, finally
  beginning to approach a dynamically relevant regime. It seems timely\, th
 erefore\, to compare the results of those simulations with the various con
 ceptual cartoons of the geodynamo that have been developed over the decade
 s. One such cartoon is presented here\, based in part on helical wave disp
 ersion within the Earth's core. This cartoon is far from the standard mode
 l\, but nevertheless seems consistent with the evidence of the numerical s
 imulations. Of course\, understanding the numerical simulations is not at 
 all the same as understanding the geodynamo\, but perhaps it is a start.
