Climate reconstructions provide important insight into past climate variability and help us to understand the large-scale climate drivers and impact of climate change. However, our knowledge about long-term year-to-year climate variability is still limited due to the lack of high-resolution reconstructions. Here, we present the first precipitation reconstructions based on tree rings from Pinus koraiensis (Korean pine) from three sites placed along a latitudinal (330 km) gradient in the Sikhote-Alin' mountains in the Russian Far East. The tree-ring width chronologies were built using standard tree-ring procedures. We reconstructed the April–June precipitation for the southern Sikhote-Alin' (SSA), March–June precipitation for the central Sikhote-Alin' (CSA) and March–July precipitation for the northwestern Sikhote-Alin' (NSA) over the years 1602 to 2013, 1804 to 2009 and 1858 to 2013, respectively. We found that an important limiting factor for Korean pine growth was precipitation within the period when the air current coming from the continent during the cold period is replaced with the impact of the wet ocean air current. We identified that common wet years for SSA, CSA and NSA occurred in 1805, 1853, 1877, 1903, 1906, 1927, 1983 and 2009 and common dry years occurred in 1821, 1869, 1919, 1949 and 2003. Our reconstructions have 3-, 15- and 60-year periods, which suggests the influence of the El Niño–Southern Oscillation and Pacific Decadal Oscillation on the region's climate and relevant processes. Despite the impact of various global processes, the main contribution to precipitation formation in the study area is still made by the Pacific Ocean, which determines their amount and periodicity.

Sikhote-Alin'山脉基于树轮的春季降水重建

气候重建为过去的气候变化提供了重要的见识，并帮助我们了解了大规模的气候驱动因素和气候变化的影响。但是，由于缺乏高分辨率的重建，我们对长期逐年气候变化的了解仍然有限。在这里，我们提出了基于红松树年轮的首次降水重建（朝鲜松）来自俄罗斯远东地区Sikhote-Alin'山中沿纬度（330公里）坡度分布的三个地点。使用标准的树年轮程序建立树年轮宽度年表。多年来，我们重建了锡克特-阿林南部（SSA）的4月至6月降水，锡克特-阿林中部（CSA）的3月至6月降水以及锡克特-阿林西北部（NSA）的3月至7月降水。 1602至2013、1804至2009和1858至2013。我们发现，对于朝鲜松生长的一个重要限制因素是在寒冷时期来自大陆的气流被湿海气流的影响所取代的时期内的降水。我们确定SSA，CSA和NSA的常见潮湿年份发生在1805、1853、1877、1903、1906、1927，1983年和2009年以及常见的干旱年份分别发生在1821年，1869年，1919年，1949年和2003年。我们的重建期分别为3年，15年和60年，这表明厄尔尼诺现象-南方涛动和太平洋年代际涛动对海平面的影响。地区的气候和相关过程。尽管受到各种全球过程的影响，但太平洋仍然是研究区域降水形成的主要因素，这决定了它们的数量和周期性。
