Dynamo Models of the Solar Cycle: Current Trends and Future Prospects

Abstract

The magnetic cycle of the Sun, as manifested in the cyclic appearance of sunspots, significantly influences our space environment and space-based technologies by generating what is now termed as space weather. Long-term variation in the Sun's magnetic output also influences planetary atmospheres and climate through modulation of solar irradiance. Here, I summarize the current state of understanding of this magnetic cycle, highlighting important observational constraints, detailing the kinematic dynamo modeling approach and commenting on future prospects.Comment: To appear in the Bulletin of the Astronomical Society of India, Proceedings of the 1st Asia Pacific Solar Physics Meetin
