A Dynamo-Based Prediction of Solar Cycle 25

The solar activity cycle varies in amplitude. last Solar Cycle 24 is the weakest past century. Sun’s dominates Earth’s space environment. frequency and intensity of follow cycle. Hence there are practical needs to know amplitude upcoming 25. Dynamo-based predictions not only provide forecasts, but also offer an effective way evaluate our understanding In this article we apply method first successful dynamo-based prediction developed for predict 25, so that can verify whether previous success repeatable. shows 25 would be about 10% stronger than with 126 (international sunspot number Version 2.0). result suggests will beginning a Maunder-like grand minimum as suggested by some publications. behavior four five years confirm captures key mechanism variability, which polar field around model.
