Possible Interactions between Some Solar Activity Indicators for the Last two Cycles
Abstract
In this study we investigated the possible linear and nonlinear interaction between some solar activity indicators which are MCMESI, Fl, SSA, SSN, F10.7 and TSI for the time period of 1996-2018. Here, we used Convergent Cross Mapping (CCM) to examine the non- linear relationship and cross-correlation analysis to examine the linear relationship between the MCMESI and all other solar activity indicators. We found that FI, SSN, F10.7 and SSA show symmetrical relationship while the only TSI data show moderate asymmetric relationship with the MCMESI. The highest nonlinear relationship with the MCMESI is obtained for F10.7 data. This relationship is a symmetrical bidirectional coupling; when the library sample size gets smaller CCM score is increasing up to about 50 then it decreasing sharply. As a result, we can get information about the future of both data sets from each other's manifold. From the cross correlation analysis we also found that the F10.7 has the strongest correlation with the MCMESI. Thus, we may argue that this relationship can be used for further dynamical modelling and prediction approaches.
