摘要
Seven proxies of summer temperature in Northern Fennoscandia, sea surface temperature in the North Atlantic and solar activity were analyzed over AD 1567-1986. A stable and significant positive correlation between summer temperatures in Northern Fennoscandia and sea surface temperature in the North Atlantic is shown to exist during the entire time interval. In addition, a significant correlation between solar activity and (a) summer temperature in Northern Fennoscandia as well as (b) surface temperature in the North Atlantic was found during AD 1715-1986. Throughout 1567-1715 correlation is less significant and has an opposite sign. Thus we show that the variation of sea surface temperature in the North Atlantic could be a physical agent, which transferred solar influence on Northern Fennoscandian temperature at least during AD 1715-1986.
