Passos, D. and Lopes, I. (2012), "Effects of cyclic fluctuations in meridional circulation using a
low-order dynamo model", MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 422, 2: 1709-1713.
Abstract: 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.
