Abstract: 

The aim of the study is to assess the influence of solar activity on the climate system of the Earth by assessing the conjugacy of global sea-surface temperature (SST), specific atmospheric humidity, and solar activity indices. The methods of mathematical statistics are widely used in the analysis of data on SST, specific humidity of the Earth’s atmosphere and solar activity. On the basis of series of SST and specific humidity of the atmosphere pre-filtered from their high-frequency components their statistically significant conjugacy is established. Spectral analysis (periodogram-analysis, cross-spectral analysis) revealed a clear 11-year solar cycle in changes in SST and atmospheric specific humidity. The study of cyclic (quasiperiodic) effects of internal and external factors on the climate is important for understanding the role of “small” forces in modulating cyclic fluctuations in the climate system.

Key words:
