论文摘要
众所周知，太阳活动的南北不对称性中存在〜12年和〜51年的周期性。但是，这些起源以及众所周知的南北不对称性相对较短的周期性尚不清楚。在这里，我们分析了1874 - 2017年期间格林威治光旋光结果（GPR）和脱骨光镜数据（GPR）和脱骨光镜数据（DPD）的合并数据，以及巨型行星轨道位置的数据（Ecliptic Longitudes）在10天间间隔的10天间隔内在1600-20999999999年期间。我们的分析表明，太阳活动的南北不对称性〜12年和〜51年的周期性是北部和南部山脉中〜11年和〜51年活性周期的优势差异的表现。在1874年至2017年期间，发现巨型行星的莫尔特小波功率光谱和巨型行星轨道位置的平均绝对差异是相似的。特别是，有一个暗示，在巨大行星的轨道位置的平均绝对差异中，太阳群面积的南北不对称区域的约12年和〜51年的周期性发生在大约相同的时间。因此，我们建议，巨型行星的某些特定构型可能会影响太阳活动的南北不对称的〜12年和〜50年的周期性。
The existence of ~12-year and ~51-year periodicities in the north-south asymmetry of solar activity is well known. However, the origin of these as well as the well-known relatively short periodicities in the north-south asymmetry is not yet clear. Here we have analyzed the combined daily data of sunspot groups reported in Greenwich Photoheliographic Results (GPR) and Debrecen Photoheligraphic Data (DPD) during the period 1874-2017 and the data of the orbital positions (ecliptic longitudes) of the giant planets in ten-day intervals during the period 1600-2099. Our analysis suggests that ~12-year and ~51-year periodicities in the north-south asymmetry of solar activity are the manifestations of the differences in the strengths of ~11-year and ~51-year periodicities of activity in the northern- and southern-hemispheres. During the period 1874-2017 the Morlet wavelet power spectra of the north-south asymmetry of sunspot-group area and the mean absolute difference of the orbital positions of the giant planets are found to be similar. Particularly, there is a suggestion that the ~12-year and ~51-year periodicities in the north-south asymmetry of sunspot-group area occurred during approximately the same times as the corresponding periodicities in the mean absolute difference of the orbital positions of the giant planets. Therefore, we suggest that there could be influence of some specific configurations of the giant planets in the origin of the ~12-year and ~50-year periodicities of the north-south asymmetry of solar activity.
