Does a low solar cycle minimum hint at a weak upcoming cycle?

Zhan-Le Du, Hua-Ning Wang

Abstract

Abstract The maximum amplitude (Rm ) of a solar cycle, in the term of mean sunspot numbers, is well-known to be positively correlated with the preceding minimum (Rmin ). So far as the long term trend is concerned, a low level of Rmin tends to be followed by a weak Rm , and vice versa. We found that the evidence is insufficient to infer a very weak Cycle 24 from the very low Rmin in the preceding cycle. This is concluded by analyzing the correlation in the temporal variations of parameters for two successive cycles.
