DESCRIPTION:The eleven year solar activity&nbsp\;cycle is a remarkable exa
 mple of regular behaviour emerging from an extremely turbulent system. The
  origin of this behaviour is a dynamo that involves the complicated intera
 ction of rotation\, turbulence and magnetic field.&nbsp\;An outstanding pr
 oblem of astrophysics and mathematical physics &nbsp\;is how to describe t
 he statistics of systematic behaviour&nbsp\;emerging from the underlying c
 haos\, given that simulation of astrophysical objects is simply impossible
 . Here I shall introduce these fascinating dynamo phenomena and describe m
 odern methods for tackling these interactions over vast ranges of spatial 
 and temporal scales.
