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

The Origin of Helicity in Solar Active Regions
We present calculations of helicity based on our solar dynamo model and show
that the results are consistent with observational data.Comment: To appear in the Proceedings of IAU Symposium 22
The role of magnetic buoyancy in a Babcock-Leighton type solar dynamo
We study the effects of incorporating magnetic buoyancy in a model of the solar dynamo-which draws inspiration from the Babcock-Leighton idea of surface processes generating the poloidal field. We present our main results here
