“…It is well known that the Sun has variable activity, and the study of solar activity variation and its effect on the Earth on a scale of 1–100 years is one of the main tasks of solar and solar‐terrestrial physics (e.g., Bhargawa & Singh, 2021; Christensen‐Dalsgaard, 2021; De Jager, 2005; Gopalswamy et al., 2020; Hathaway, 2015; Sasikumar Raja et al., 2019; Schwander et al., 2017; Schwenn, 2006; Usoskin, 2017). In the literature, in addition to the well‐studied solar cycles of Schwabe (11 years) and Hale (22 years), the possibility of the Sun approaching the minimum of the Gleissberg (about 90 years) cycle, the so‐called grand minimum, is widely discussed (Dreschhoff et al., 2015; Feynman & Ruzmaikin, 2011; Nagovitsyn et al., 2021; Svalgaard et al., 2005; Zolotova & Ponyavin, 2014).…”
