蝶形图中成对翅膀的相移
The Phase Shifts of the Paired Wings of Butterfly Diagrams
摘要：
利用1874年5月至2008年11月英国皇家格林尼治天文台/美国空军/NOAA观测的太阳黑子群和1919年3月至1989年12月的Carte Synoptique太阳暗条，研究了太阳黑子和暗条活动蝴蝶图中成对翅膀的相对相移.太阳黑子群（或暗条）的垂直迁移在南北半球是不同步的，在一个周期内，它们的蝶形图的成对翅膀之间存在相对相移，使得成对翅膀在太阳赤道上的空间不对称。由此推断，在一个周期内，半球太阳活动强度在蝶形图的成对翅膀内的演化方式应该是相似的，使得成对翅膀恰好且仅保持南北半球太阳活动强度之间的相位关系，而蝶形图的成对翅膀之间的相对相移应该会带来半球太阳活动强度几乎相同的相对相移。
英文摘要：
Sunspot groups observed by Royal Greenwich Observatory/US Air Force/NOAA from May 1874 to November 2008 and the Carte Synoptique solar filaments from March 1919 to December 1989 are used to investigate the relative phase shift of the paired wings of butterfly diagrams of sunspot and filament activities. Latitudinal migration of sunspot groups (or filaments) does asynchronously occur in the northern and southern hemispheres, and there is a relative phase shift between the paired wings of their butterfly diagrams in a cycle, making the paired wings spatially asymmetrical on the solar equator. It is inferred that hemispherical solar activity strength should evolve in a similar way within the paired wings of a butterfly diagram in a cycle, making the paired wings just and only keep the phase relationship between the northern and southern hemispherical solar activity strengths, but a relative phase shift between the paired wings of a butterfly diagram should bring about an almost same relative phase shift of hemispheric solar activity strength.
