Binary Content Simulation of solar magnetic field transport and accumulation of polar magnetic fields during a solar cycle

Abstract/Description: "In this research, a model of the dynamics of solar magnetic fields was developed. The solar magnetic fields are generated at a low-latitude zone by their upwelling from solar interior. Then they are transported by the solar meridional flow to high latitudes, which leads to a strong accumulation of magnetic fields in the polar regions near the minima of solar activity. The mechanisms of appearance and transport of magnetic field at the solar surface are studied well enough to provide mathematical description that allows to construct a model. However, the model cannot provide acceptable output without distinctive mechanisms of disappearance of the magnetic fields from the solar surface. Therefore, to construct the accurate simulation of solar cycle, three mechanisms of vanishing of magnetic fields were tested: magnetic field decay, vertical (radial) flow, and vertical (radial) diffusion. It was found that for reasonable parameters this model described the man features of solar magnetic field dynamics: the meridional poleward motion of magnetic fields, their accumulation on the polar region near the minima of solar activity, and the reversal of the solar magnetic field. The complete solar cycle was simulated, tested, and presented; the results were compared with solar data"--page v.
