  The inherent stochastic and nonlinear nature of the solar dynamo makes the
strength of the solar cycles vary in a wide range, making it difficult to
predict the strength of an upcoming solar cycle. Recently, our work has shown
that by using the observed correlation of the polar field rise rate with the
peak of polar field at cycle minimum and amplitude of following cycle, an early
prediction can be made. In a follow-up study, we perform SFT simulations to
explore the robustness of this correlation against variation of meridional flow
speed, and against stochastic fluctuations of BMR tilt properties that give
rise to anti-Joy and anti-Hale type anomalous BMRs. The results suggest that
the observed correlation is a robust feature of the solar cycle and can be
utilized for a reliable prediction of peak strength of a cycle at least 2 to 3
years earlier than the minimum.
