Description
During a solar magnetic field reversal the magnetic dipole
moment does not
vanish, but migrates between poles, in contradiction to the
predictions of mean-
field dynamo theory. We try to explain this as a consequence of
magnetic
fluctuations. We used the statistics of fluctuations to estimate
observable
signatures. Simple statistical estimates, taken with results from
mean-field
dynamo theory, suggest that a non-zero dipole moment may
persist through a
global field reversal. Fluctuations in the solar magnetic field may
play a key role
in explaining reversals of the solar dipole.
