Juniper tree-ring data from the Kuramin Mountains (Republic of Tajikistan), reveals changing summer drought signals in western Central Asia

We present a regional tree-ring chronology from moisture-sensitive Juniperus seravschanica from the Kuramin Mountains (Tajikistan) in western Central Asia, which is used to reveal past summer drought variability from CE 1650 to 2015. The chronology accounts for 40.5% of the variance of the June–July self-calibrating Palmer Drought Severity Index (scPDSI) during the instrumental period (1901 to 2012).本研究基于中亚西部塔吉克斯坦库拉明山脉地区对水分敏感的赛拉夫申圆柏（Juniperus seravschanica），构建了区域树轮年表，该年表可用于揭示公元1650年至2015年的历史夏季干旱变化特征。在1901年至2012年的器测时段内，该年表能够解释6-7月自校准帕默尔干旱强度指数（self-calibrating Palmer Drought Severity Index, scPDSI）40.5%的方差变异。
