A Critical Comment on “Can Solar Cycle 25 Be a New Dalton Minimum?”

چکیده

Abstract The sunspot number is the most used solar-activity index to study behavior of solar activity. In this work, we reproduce methodology Coban, Raheem, and Cavus ( Solar Phys . 296 , 156, 2021) using a long short-term memory model with daily data from American Association Variable Star Observers (AAVSO) predict maximum amplitude Cycle 25. We have also that same values official (Version 2) Sunspot Index Long-term Observations (SILSO). objective work analyze if predictions obtained agree observed available for current Thus, conclude are not reproducing well 25 in its rising phase. Moreover, contrary previous prediction, no minor peak occurred February 2022, it seems unlikely combination level 24 constitutes new Dalton-type Minimum, such as (2021) proposed.

Interactive comment on “How can we understand the solar cycle signal on the Earth’s surface?” by

This paper studies the 11-year solar cycle signal in Earth’s surface using historical datasets and the surface evidence is further supported by the zonal mean vertical profile using ERA-Interim and previously archived model simulations. The authors present many surface and zonal mean quantities that are composited between high and low solar years. Although majority of the results presented here...

Lost sunspot cycle in the beginning of Dalton minimum: New evidence and consequences

[1] We have recently suggested that one solar cycle was lost in the beginning of the Dalton minimum during 1790s [Usoskin et al., 2001]. Earlier, this cycle has been combined with the preceding activity to form the exceptionally long solar cycle 4 in 1784-1799 with an irregular phase evolution. Here we show that historical data of auroral occurrence provide independent evidence for the existenc...

Deciphering Solar Magnetic Activity: Spotting Solar Cycle 25

We present observational signatures of solar cycle 25 onset. Those signatures are visibly following a migratory path from high to low latitudes. They had starting points that are asymmetrically offset in each hemisphere at times that are 21–22 years after the corresponding, same polarity, activity bands of solar cycle 23 started their migration. Those bands define the so-called “extended solar ...
