Query: Effects of cyclic fluctuations in meridional circulation using a low
  order dynamo model   We develop and subsequently explore the solution space of a simple flux
transport dynamo model that incorporates a time dependent large scale
meridional circulation. Based on recent observations we prescribed an
analytical form for the amplitude of this circulation and study its impact in
the evolution of the magnetic field. We find that cyclic variations in the
amplitude and frequency of the meridional flow affect the strength of the solar
cycle. Variations in the amplitude of the fluctuations influence the shape of
the solar cycle but are only relevant to the cycle's strength variations when
they occur at a frequency different from or out of phase of the solar cycle's.
