| Popis: | The time series describing the solar activity variations in the diverse solar layers are analyzed in terms of the developed method of the flicker-noise diagnostic which allows one to extract the dynamic characteristics of the process under study. The revealed results allow us to conclude that in all studied solar processes short term variations of the observational variables (with typical time less than ~3 years) reflect the behavior of some global dynamics. The dynamic characteristics turned out to be similar for the processes which are observed at the level of the solar photosphere and gradually changes in the solar atmosphere. That is why all Sun layers can be considered as a single dynamic system. We find that the short term variations of the solar neutrino capture rate are not random but are caused by some dynamic process. The analysis of solar total irradiance time series in terms of the applied method allows us to suggest that the mentioned dynamic processes exists in the solar core. |
