Abstract
The wavelet transform is used to analyze periodicities in the Wolf numbers, calcium plage areas, coronal intensities, net solar magnetic field intensities, fluxes of solar radiation at a wavelength of 10.7 cm, and geomagnetic planetary indexes. The periodicities with scales varying between 5 and 100 years have been detected. A correlation between the time series of temperature in Tomsk and solar activity is analyzed. No correlation is found between the initial series; however, a significant correlation is established between the periodicities in the time series of temperature and individual solar activity indexes.
