欧洲赤松（Pinus sylvestris L.）由于其在欧洲大陆大部分地区的共同分布，在欧洲树木气候学研究中被广泛使用的树种。几乎所有的研究都发现径向生长与夏季温度密切相关，这一结果反映了树木在高海拔/高纬度环境中生长的生态生理极限。由于对这些地点的关注，欧洲基于树木年轮代理的温度重建存在地理和季节偏差。为了克服温带低地树木年轮数据的有限性，我们提出了一个北方波兰年轮宽度年表，该年表是从生活和历史上的苏格兰松材料开发的，具有强烈的共同生长信号，可以追溯到公元1200年。对气候-生长关系的调查发现，在树木年轮形成期间，年与年之间的年轮宽度变化与生长季节之前的冷季温度（11月至4月）的相关性比夏季温度更强。根据这种关系，有可能重建过去810年的冷季温度条件。空间场与网格化仪器记录的相关性表明，重建提供了相关的冷季温度信息的陆地地区接壤的北大西洋和波罗的海，低地和高地的西欧和中欧，以及东部和中部的俄罗斯内陆。尽管试图找到与北大西洋涛动的固定关系的尝试失败，但与几个冷季温度重建的比较证实了我们重建的北方波兰和更广泛地区的温度序列之间的长期联系。
Scots pine (Pinus sylvestris L.) is a widely used tree species in European dendroclimatology studies due to its common distribution across much of the continent. Almost all studies find radial growth strongly related to summer temperature, a result reflecting site selection at high elevation/latitude environments where trees grow at their ecophysiological limits. Due to the amount of attention spent on these sites there is a geographical and seasonal bias in temperature reconstructions based upon tree‐ring proxies in Europe. To overcome the limited availability of tree‐ring data in temperate lowlands, we present a northern Poland ring‐width chronology developed from living and historic Scots pine material with a strong common growth signal going back to AD 1200. Investigations into climate‐growth relationships found year‐to‐year ring‐width variability to be more strongly correlated to cold season temperature (November to April) prior to the growing season than summer temperatures during tree‐ring formation. Based on this relationship it was possible to reconstruct cold season temperature conditions for the last 810 years. Spatial field correlations with gridded instrumental records indicated that the reconstruction provides relevant cold season temperature information across the land regions bordering the North Atlantic Ocean and Baltic Sea, lowlands and uplands of western and central Europe, and the eastern and central interior of Russia. Despite an unsuccessful attempt to find a stationary relationship with the North Atlantic Oscillation, comparisons with several cold season temperature reconstructions confirmed the long‐term connection between our reconstructed temperature series for northern Poland and the wider area.
