Pinus sylvestris L. (Scots pine) is the main forest tree species in Burabai National Park. Trees here grow under continental climate conditions. There are no dendroclimatological studies based on Scots pine of this region. The purpose of this study was to find the relationships between tree-ring widths and climate. For this purpose, a total of 176 cores from 100 Scots pine trees were collected. After measuring tree-ring widths, standard chronology building methods were used, and three site chronologies were constructed. Correlation coefficients between tree-ring widths with temperature and precipitation were calculated. Precipitation from October of the previous year to July of current year had a positive influence on tree-ring widths and August-September precipitation have the opposite effect. Temperature in the winter had positive effect for tree-ring growth but significantly negative during summer. Effects of climate changes on tree-ring widths were observed. The variation and sensitivity of tree-ring widths increased after 1940s. An increasing trend in precipitation, temperature, and tree-ring widths were clearly observed. In conclusion, tree-rings of Scots pine in Burabai are highly sensitive to growing site conditions and are affected by climate changes.

“…Inner and northern Asia is also one of the most sensitive areas to climate change in Asia, and many treering-based climate reconstructions have been conducted in this area (Briffa et al 1995;Esper et al 2001Esper et al , 2010Pederson et al 2001;Solomina et al 2007;Agafonov and Kukarskikh 2008;Magda et al 2011;Chen et al 2013Chen et al , 2015Liu et al 2013;Gou et al 2014;Bao et al 2015). Dendroclimatological studies at the high-latitude sites of northern Asia have been focused on temperature reconstruction and provided the information about the summer temperature variations and recent global warming (Briffa et al 1995(Briffa et al , 2013Naurzbaev et al 2002;Esper et al 2010).…”

Based on the significant positive correlations between the regional tree-ring width chronology and local climate data, the total precipitation of the previous July to the current June was reconstructed since AD 1760 for the northwestern Chinese Altay. The reconstruction model accounts for 40.7 % of the actual precipitation variance during the calibration period from 1959 to 2013. Wet conditions prevailed during the periods 1764-1777, 1784-1791, 1795-1805, 1829-1835, 1838-1846, 1850-1862, 1867-1872, 1907-1916, 1926-1931, 1935-1943, 1956-1961, 1968-1973, 1984-1997, and 2002-2006. Dry episodes occurred during 1760-1763, 1778-1783, 1792-1794, 1806-1828, 1836-1837, 1847-1849, 1863-1866, 1873-1906, 1917-1925, 1932-1934, 1944-1955, 1962-1967, 1974-1983, 1998-2001, and 2007-2012. The spectral analysis of the precipitation reconstruction shows the existence of some cycles (15.3, 4.5, 3.1, 2.7, and 2.1 years). The significant correlations with the gridded precipitation dataset revealed that the precipitation reconstruction represents the precipitation variation for a large area of the northern part of inner Asia. A comparison with the precipitation reconstruction from the southern Chinese Altay shows the high level of confidence for the precipitation reconstruction for the northwestern Chinese Altay. Precipitation variation of the northwestern Chinese Altay is positively correlated with sea surface temperatures in tropical oceans, suggesting a possible linkage of the precipitation variation of the northwestern Chinese Altay to the El Niño-Southern Oscillation (ENSO) and the North Atlantic Oscillation (NAO). The synoptic climatology analysis reveals that there is the relationship between anomalous atmospheric circulation and extreme climate events in the northwestern Chinese Altay.
