Influence of Solar Activity on Earth's Climate

Here we reconsider some astrophysical, geophysical and meteorological indicators about the possible influence of solar activity on space and terrestrial weather. We used wavelet transforms to perform spectral analysis of several solar activity and geophysical data in order to detect their common oscillations, and to study the temporal stability and statistical significance of such oscillations. Besides, we also calculated the cross-correlation functions between the solar activity and geophysical time series. The obtained results indicate that solar activity may have a significant influence on weather on Earth by perturbing the global atmospheric circulations and geomagnetic field, as well as by affecting Earth’s albedo and cloud formation.Several possible physical mechanisms which explain that influence is also suggested.
