论文摘要
太阳显示出各种各样的时间变化，从几秒钟到几十年甚至几个世纪，将短期和长期分为两类。据信太阳发电机机制是造成太阳发生的这些全球变化的原因。因此，已经提出了许多发电机模型来解释太阳的观察到的行为。该论文主要集中于研究太阳的\ lt \变化，并为太阳能动力模型提供了各种输入。有了对该主题的重新兴趣，已经开发了几种自动技术，用于广泛的数据分析，以应用于长期数据集并在本文中介绍。这种方法提供了更好的一致性并消除了人类的主观性，这是过去的一种正常实践。在这里观察到的Q的半阴茎与Umbra面积比的变化将在黑子模拟中提供约束。此外，小小的和大点的行为没有任何差异并不支持全球和局部发电机的想法。在磁化图中观察到的两类BMR进一步验证了这种行为。 NSSL的重要性在太阳发电机模型的背景下不是很好地研究，但是值得等待，以了解其对理解太阳能发电机的重要性。最后，需要使用更全面的数据集（包括更强的周期）进一步验证此处介绍的倾斜淬火指示。
The Sun shows a wide range of temporal variations, from a few seconds to decades and even centuries, broadly classified into two classes short-term and Long-term. The solar dynamo mechanism is believed to be responsible for these global changes happening in the Sun. Hence, many dynamo models have been proposed to explain the observed behaviour of the Sun. This thesis is primarily focused on studying the \lt\ variation of the Sun and provides various inputs to the solar dynamo models. With a renewed interest in the subject, several automatic techniques have been developed for extensive data analysis as applied to long-term datasets and presented in this thesis. This approach provides better consistency and eliminates human subjectivity, which has been a normal practice in the past. The variation of penumbra to umbra area ratio, q, observed here, will provide constraints in sunspot simulations. In addition, the absence of any difference in the behaviour of small and big spots does not support the idea of the global and local dynamo. Two classes of BMRs observed in the magnetograms further verify this behaviour. The importance of the NSSL is not studied so well in the context of solar dynamo models, but it will be worth waiting to see its significance for understanding solar dynamo. Finally, the indication of tilt quenching presented here needs to be further verified using the more comprehensive data set, including stronger cycles.
