| Zusammenfassung |
| We analyse phase lags between the 11-year variations of three records: the
semi-annual oscillation of the length of day (LOD), the solar activity (SA)
and the cosmic ray intensity (CRI). The analysis was done for solar cycles
20–23. Observed relationships between LOD, CRI and SA are discussed
separately for even and odd solar cycles. Phase lags were calculated using
different methods (comparison of maximal points of cycles, maximal
correlation coefficient, line of synchronization of cross-recurrence plots).
We have found different phase lags between SA and CRI for even and odd solar
cycles, confirming previous studies. The evolution of phase lags between SA
and LOD as well as between CRI and LOD shows a positive trend with additional
variations of phase lag values. For solar cycle 20, phase lags between SA and
CRI, between SA and LOD, and between CRI and LOD were found to be negative.
Overall, our study suggests that, if anything, the length of day could be
influenced by solar irradiance rather than by cosmic rays. |
