Solar cycle activity: A preliminary prediction for cycle #24 [PDF]

open access: yesAstronomy & Astrophysics, 2003
Solar activity forecasting is an important topic for numerous scientific and technological areas, such as space op- erations, electric power transmission lines and earth environment impact. Nevertheless, the well-known difficulty is how to accurately predict, on the basis of various recorded solar activity indices, the complete evolution of future ...

A synthesis of solar cycle prediction techniques [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 1999
A number of techniques currently in use for predicting solar activity on a solar cycle timescale are tested with historical data. Some techniques, e.g., regression and curve fitting, work well as solar activity approaches maximum and provide a month‐by‐month description of future activity, while others, e.g., geomagnetic precursors, work well near ...

Prediction of Sunspot and Plage Coverage for Solar Cycle 25 [PDF]

open access: yesThe Astrophysical Journal Letters, 2021
Abstract Solar variability occurs over a broad range of spatial and temporal scales, from the Sun’s brightening over its lifetime to the fluctuations commonly associated with magnetic activity over minutes to years. The latter activity includes most prominently the 11 yr sunspot solar cycle and its modulations.

Prediction of the amplitude of solar cycle 25 using polar faculae observations

open access: yesJournal of Space Weather and Space Climate, 2021
Based on the monthly number of polar faculae, a forecast of the amplitude of solar cycle 25 (SC25) is provided, as well as a prediction of the number of solar flares.

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.
