论文摘要
我们从对太阳能超级晶格的分形维度的分析中列出了发现,这是在太阳能周期的CA II K线中采用光学黑细胞观数据的纬度,超晶体细胞大小和太阳旋转的函数。 23。我们发现,分形尺寸倾向于从赤道的约1.37降低到两个半球的纬度20度,这表明太阳旋转速率具有增加超晶边界不规则性的作用。考虑到超晶细胞大小与分形维直接相关,我们得出结论,观察到的机制是太阳旋转会影响细胞流出强度,从而影响细胞大小,而细胞大小以及超晶格分形尺寸的纬度依赖性是其后果。
We present findings from an analysis of the fractal dimension of solar supergranulation as a function of latitude, supergranular cell size and solar rotation, employing spectroheliographic data in the Ca II K line of solar cycle no. 23. We find that the fractal dimension tends to decrease from about 1.37 at the equator to about 1 at 20 degree latitude in either hemisphere, suggesting that solar rotation rate has the effect of augmenting the irregularity of supergranular boundaries. Considering that supergranular cell size is directly correlated with fractal dimension, we conclude that the mechanism behind our observation is that solar rotation influences the cell outflow strength, and thereby cell size, with the latitude dependence of the supergranular fractal dimension being a consequence thereof.
