AbstractThe periodicity of the high-latitude solar activity has been studied using monthly-averaged polar facula counts obtained at the National Astronomical Observatory of Japan (NAOJ) and the annual number of polar faculae observed by Mount Wilson Observatory (MWO). The complex Morlet wavelet was utilized to analyze the periodicity, in the two data sets. For the NAOJ and MWO data, the most eminent period is 10.89 and 10.48 years. respectively. which is the Schwabe period of the high-latitude solar activity. All possible periods detected at the low-latitude solar activity were also detected in the two data sets, and we found no distinct periods existing just in the two data Sets of the hi-h-latitude solar activity. The periodicity of the high-latitude solar activity is inferred to be the same as that of the low-latitude solar activity.
