Improvements and Applications of Kinematic Models of the Solar Magnetic Cycle
The best tools we have for understanding the origin of solar magnetic
variability are kinematic dynamo models. During the last decade, this
type of models has seen a continuous evolution and has become
increasingly successful at reproducing solar cycle characteristics.
However, the ingredients that are part of these models remain poorly
constrained which allows one to obtain solar-like solutions by ``tuning"
the input parameters, leading to controversy regarding which parameter
set is more appropriate.
In this presentation we will visit each of those ingredients and the
work we have done to constrain their free parameters. Additionally, and
using the improved model as a starting point, we will explore the causes
that led to the unusually quiet minimum of cycle 23 and discuss results
which suggest that there is a problem with the current solar cycle
