چکیده انگلیسی
Time evolution of growing season temperatures in the Northern Hemisphere was analyzed using both wavelet and Fourier approaches. A century-scale (60-140 year) cyclicity was found in the summer temperature reconstruction from the Taymir peninsula (â¼72° N, â¼105° E) and other high-latitude (60-70° N) regions during the time interval AD 1576-1970. This periodicity is significant and consists of two oscillation modes, 60-70 year and 120-140 year variations. In the summer temperatures from the Yamal peninsula (â¼70° N, â¼67° E) only a shorter-term (60-70 year) variation is present. A comparison of the secular variation in the Northern Hemisphere temperature proxies with the corresponding variations in sunspot numbers and the fluxes of cosmogenic 10Be in Greenland ice shows that a probable cause of this variability is the modulation of temperature by the century-scale solar cycle of Gleissberg. This is consistent with the results obtained previously for Northern Fennoscandia (67°-70° N, 19°-33° E). Thus, evidence for a connection between century-long variations in solar activity and climate was obtained for the entire boreal zone of the Northern Hemisphere.
