Impact of Anomalous Active Regions on the Large Scale Magnetic Fields of the Solar Cycle

Emergence of anomalous bipolar magnetic regions (combinations of anti-hale and anti-joy regions) on the solar surface can influence cycle to cycle variability and irregularities. We perform a comprehensive analysis of the dipole moment and polar field build up due to the appearance of anomalous active regions on the solar surface using a solar surface flux transport model. Our aim is to study the differences and the similarities between these anomalous regions and their effect in global solar cycle dynamics. Although these regions appear in small numbers, if they carry significant flux, they are found to significantly impact the polar field strength and thereby, the amplitude of future cycles.
