The Solar Cycle

open access: yesLiving Reviews in Solar Physics, 2015
The solar cycle is reviewed. The 11-year cycle of solar activity is characterized by the rise and fall in the numbers and surface area of sunspots. A number of other solar activity indicators also vary in association with the sunspots including; the 10.7

An Updated Solar Cycle 25 Prediction With AFT: The Modern Minimum

open access: yesGeophysical Research Letters, 2018
Over the last decade there has been mounting evidence that the strength of the Sun's polar magnetic fields during a solar cycle minimum is the best predictor of the amplitude of the next solar cycle.

The Solar Cycle

open access: yesLiving Reviews in Solar Physics, 2010
The Solar Cycle is reviewed. The 11-year cycle of solar activity is characterized by the rise and fall in the numbers and surface area of sunspots. We examine a number of other solar activity indicators including the 10.7 cm radio flux, the total solar ...

Geomagnetic activity recurrences for predicting the amplitude and shape of solar cycle n. 25

open access: yesJournal of Space Weather and Space Climate, 2021
Predicting solar activity is one of the most challenging topics among the various Space Weather and Space Climate issues. In the last decades, the constant enhancement of Space Climate data improved the comprehension of the related physical phenomena and

Solar Cycle 25 Prediction Using N-BEATS

open access: yesThe Astrophysical Journal, 2023
Solar activities lead to Sun variation with an 11 yr periodicity. The periodic variation affects space weather and heliophysics research. So it is important to accurately predict solar cycle variations. In this paper, we predicted the ongoing Solar Cycle

A critical evaluation of decadal solar cycle imprints in the MiKlip historical ensemble simulations [PDF]

open access: yesWeather and Climate Dynamics, 2023
Studies concerning solar–terrestrial connections over the last decades claim to have found evidence that the quasi-decadal solar cycle can have an influence on the dynamics in the middle atmosphere in the Northern Hemisphere (NH) during the winter season.

Complex Network Study of Solar Magnetograms

open access: yesEntropy, 2022
In this paper, we study solar magnetic activity by means of a complex network approach. A complex network was built based on information on the space and time evolution of sunspots provided by image recognition algorithms on solar magnetograms taken ...
