Standard prediction of solar cycles

Geomagnetism and Aeronomy, 2008
To make a long-term prediction of the solar cycle in a standard way (GOST 25645.302-83), it is necessary to know the instant of the activity minimum onset, the determination of which is difficult during the decline stage of the previous cycle. The dependence of the long-term prediction error on the time of shift (t) relative to the solar activity ...

Prediction of Solar Cycle Maximum Using Solar Cycle Lengths

Solar Physics, 2008
If the rise time RT, fall time FT, and total time TT (i.e., RT+FT) of a solar cycle are compared against the maximum amplitude Rz(max ) for the following cycle, then only the association between TT and Rz(max ) is inferred to be well anticorrelated, inferring that the larger (smaller) the value of Rz(max ) for the following cycle, the shorter (longer ...

Solar cycle characteristics and their application in the prediction of cycle 25

Journal of Atmospheric and Solar-Terrestrial Physics, 2018
Abstract The Solar Influences Data Analysis Center (SIDC) issued a new version (version 2) of the sunspot number data in July 2015. The 13-month smoothed monthly sunspot number from the new version is used for the first time to research the relations among the feature parameters of solar cycles under the bimodal distribution for the modern era cycles

A Prediction for the 24th Solar Cycle

Central European astrophysical bulletin, 2008
The aim of the present analysis is to forecast the strength of the next solar maximum of the 24th cycle. We correlate the relative sunspot numbers in the epochs of solar activity minima and maxima. Using this method, the estimated relative sunspot number (also called the Wolf number) of the next solar maximum is in the range 67 - 81, i.e., about 40 ...

The Prediction of Maximum Amplitudes of Solar Cycles and the Maximum Amplitude of Solar Cycle 24

Chinese Journal of Astronomy and Astrophysics, 2002
We present a brief review of predictions of solar cycle maximum ampli- tude with a lead time of 2 years or more. It is pointed out that a precise prediction of the maximum amplitude with such a lead-time is still an open question despite progress made since the 1960s.

Can the Solar Cycle Amplitude Be Predicted Using the Preceding Solar Cycle Length?

Solar Physics, 2008
In this work, the evolution of the relationship between Solar Cycle Length of solar cycle n (SCLn) and Solar Cycle Amplitude of the solar cycle n+1 (SCAn+1) is studied by using the RZ and RG sunspot numbers. We conclude that this relationship is only strongly significant in a statistical sense during the first half of the historical record of RZ ...

A prediction for the solar cycle 24

2009
Applying and combining different methods, the strength and epochs for the next 24th solar cycle are predicted. The combined method consists of the three parts: (i) the calculation of the asymmetry of the ascending and descending solar cycle phases, (ii) the correlation of the relative sunspot numbers in and around solar activity minima with the ...
