The influence of climatic factors on the tree-ring of Pinus koraiensis was studied in the middle Sikhote-Alin Mountains, the Russian Far East. Ring-width residual chronologies were developed for two ecologically different sites. Both precipitation and air temperature affected the radial growth significantly. March–April mean temperature, May–August mean temperature (1678–2009) and March-July precipitation (1717–2009) have been reconstructed from Korean pine tree rings. These represent the first spring-summer mean temperature and total precipitation spring-summer reconstructions for this region (42.00–54.00°N and 132.00–138.00°E). As a result, the March-July precipitations from both chronologies were combined together into one regional chronology from (1717-2009). We found the high significant relationships between March-April air temperature and the Arctic Oscillation Index in the negative phase (the period from 1940 to 1980, R2 = 0.75) and between precipitation amount in March-July with the same Index (R2 = 0.67).
