Abstract The study of global climate warming remains open the questions about predicting process patterns and the used methods. The impact of solar activityon the Earth natural processes is being studied. The revealed features of solar activity fluctuations are consequences of the physics of the phenomenon itself, as well as delays in reactions to fluctuations in various geophysical layers of the Earth. Eleven-year cycles of precipitation dynamics observed at the Yakutsk meteorological station in comparison with solar activity cycles are described. The total number of cycles, according to the weather station, for the period from 1934 to 2018 is eleven. They are compared to eight solar activity cycles. A wavelet transformation of a series of atmospheric precipitation reveals the relationship between precipitation and solar oscillations. Even and odd precipitation cycles are highlighted, in line with Hal’s law of magnetic polarity. Positive precipitation anomalies have been found to be consistent with the maximums of odd-numbered solar cycles and the minimums of even-numbered cycles, while negative anomalies are found to be consistent with the minimums of odd-numbered and maximums of even-numbered cycles. Highlighting cyclic components can be useful in studying changes in humidity due to climate perturbations. The obtained results can be used to make climate and hydrological forecasts for the central region of Yakutia.
