A theoretical study of the build-up of the Sun's polar magnetic field by using a 3D kinematic dynamo model

25 Jan 2017 Hazra Gopal Choudhuri Arnab Rai Miesch Mark S.

We develop a three-dimensional kinematic self-sustaining model of the solar dynamo in which the poloidal field generation is from tilted bipolar sunspot pairs placed on the solar surface above regions of strong toroidal field by using the SpotMaker algorithm, and then the transport of this poloidal field to the tachocline is primarily caused by turbulent diffusion. We obtain a dipolar solution within a certain range of parameters... (read more)
