Fig. 3

A rendering of a solar dynamo simulation from Muñoz-Jaramillo et al. (2009) shows the distribution of magnetic fields within the Sun’s convection zone at a phase near solar minimum. The left meridional cut depicts the poloidal component (in purple color) and the right meridional cut depicts the toroidal component (red and blue colors indicate opposite polarities). The central yellow region corresponds to the base of the convection zone. On the right, a bar plot denotes the number of sunspots on the solar surface (with yellow lines depicting different values). Since this snapshot corresponds to a solar minimum, there are no sunspots on the surface. The full movie of the simulation can be found at https://svs.gsfc.nasa.gov/3521.
