On the possible influence of solar 11-year cycle on a climate of Southern Fennoscandia

Abstract

Abstract Three proxy records of Southern Fennoscandia climate variability were analyzed. It was found that their decadal variations correlate significantly (p=0.961-0.993) with a quasi 11-year solar cycle of Schwabe during AD 1706-1990. But two proxy records have significant decadal correlation with the index of summer North-Atlantic Oscillation (SNAO) as well. Taking into account that decadal periodicity in the SNAO index also has some correlation with the solar cycle of Schwabe, the revealed relations could be a result of influence of solar activity on the Southern Fennoscandian climate realizing by the complicated way. Possible causes of such complexity are discussed.
