论文摘要
在太阳能活动中的长期南北不对称的观察要求赤道对称(四极极)模式存在于太阳能磁场中,这与显性抗对称(偶性)模式一致。本文提出将黑子区域视为地下环形磁通量的代理,以从黑子数据中推断太阳能发电机的四极模式。北半球和南半球的环形伪升华(PF)被定义为签名的黑子区域,并根据黑尔的黑子极性规则规定了向其规定的加号或负标志。所谓的PFS的统计相关分析和小波分析显示,相对于主要的22次偶极模式的幅度相比,相对于显性22-年度振幅的幅度约为16年,幅度约为16年,幅度约为0.17。
Observations of long-term north-south asymmetry in solar activity demand the equator-symmetric (quadrupolar) mode be present in the solar magnetic field in line with the dominant antisymmetric (dipolar) mode. This paper proposes treating the sunspot area as a proxy for subsurface toroidal magnetic flux to infer the quadrupolar mode of the solar dynamo from sunspot data. Toroidal pseudo-fluxes (PF) in the northern and southern hemispheres are defined as a signed sunspot area with plus or minus sign prescribed to them in accord with the Hale's sunspot polarity rules. Statistical correlation analysis and wavelet analysis of so-defined PFs reveal quadrupolar oscillations with a period of about 16 yr and amplitude of about 0.17 relative to the amplitude of the dominant 22-yr dipolar mode.
