“…When viewed alongside a temperature reconstruction for China (Yang et al, 2002;Figure 7c), it can be seen that high-flow conditions generally correspond to warm periods and low-flow conditions generally coincide with cold periods (an exception to this occurs around AD 800). This conclusion is consistent with our previous research, which concluded that dry intervals generally coincide with cold periods in the Qilian Mountains and vice versa (Qin et al, 2011;Yang et al, 2010).…”

We developed two tree ring-width chronologies (Qilian juniper, Sabina przewalskii Kom.) for the inland Heihe River Basin in arid northwest China using a large number of tree-ring samples (217 samples/92 trees) with accurate information about pith offsets based on Regional Curve Standardization (RCS) and standard dendrochronological (STD) methodologies. Two 1422-year reconstructions of annual (August-July) streamflow for the upstream region of the Heihe River are presented. The STD and RCS reconstructions account for 53.4% and 57.2% of the actual streamflow variance during the period 1958-2006, respectively. Both reconstructions display considerable low frequency (multidecadal to multicentury) fluctuations, although the RCS based reconstruction is superior to the STD based reconstruction for retention of low-frequency trends. Low-flow years in ad are detected in both reconstructions. Both the STD and the RCS reconstructions testify to the fact that the 20th century witnessed intensified pluvial conditions in the upstream region of the Heihe River in the context of the last 1500 years. The streamflow reconstructions are anticipated to be useful to water resource planning and management for the Heihe River Basin in arid northwestern China.

“…The discrepancies between the start and end years of the above-or below-average precipitation in the different archives may be partly attributed to the different seasonality of the climate signal represented by the proxies or different regional climatic conditions. Specifically, based on the tree-ring width series, the increasing trend in annual precipitation during the past 50 years was also found on the southeastern (Bräuning and Mantwill, 2004) and northeastern TP (Qin et al, 2010(Qin et al, , 2011Yang et al, 2010b), and the unprecedented pluvial condition since the mid-1980s is consistent with the results from Liu et al (2010a). This rapid growth increase can not be attributed to the age structure of the studied trees used in developing the chronology since a homogenous age distribution of young/old trees is indicated in Figure 5d.…”

Knowledge of Asian monsoon variability remains limited because of sparse instrumental data available only for short time series. Here, an updated tree-ring width record covering the period ad 1037–2009 was developed for the south-central Tibetan Plateau (TP). Correlation analysis revealed a significant relationship ( r = 0.71) between the tree-ring index and annual (previous July to current June) precipitation series for the instrumental period 1963–2008, which accounts for 50.41% of the rainfall variability. Based on a linear regression model, the longest available regional precipitation history was reconstructed. Spatial correlation between tree ring width and annual precipitation data from previous July to current June indicates that the reconstruction is representative of precipitation changes on the south-central TP. Regional wet conditions occurred during ad 1095–1161, 1376–1403, 1414–1446, 1518–1537, 1549–1572, 1702–1757, 1848–1878 and 1891–1913, while dry periods were identified during ad1189–1242, 1256–1314, 1329–1357, 1470–1491, 1573–1623, 1636–1686, 1761–1821, 1823–1847, 1879–1890 and 1931–1985. The negative correlation between our reconstructed precipitation and India monsoon rainfall series indicates the seesaw pattern over northern and southern monsoon Asia. It is suggested that solar radiation-induced sea surface temperature (SST) anomalies over the tropical Pacific influence regional rainfall patterns. The degree of this influence has been stable at the multidecadal scale during the past 1000 years.

“…As shown by Qin et al . (), a counterclockwise atmospheric circulation (South Asian monsoon and Westerlies) dominates the area around 90–110°E, 40–50°N from April to September, a pattern that occurs during wet years. This phenomenon is supported by the positive correlations between regional precipitation and South Asian monsoon related to the Indian Ocean SST.…”

“…Therefore, a warm Atlantic would lead to a higher evaporation, and higher air temperatures would enhance the disturbance of the Westerlies and increase the cyclonic activity of precipitation. As shown by Qin et al (2011), a counterclockwise atmospheric circulation (South Asian monsoon and Westerlies) dominates the area around 90-110°E, 40-50°N from April to September, a pattern that occurs during wet years. This phenomenon is supported by the positive correlations between regional precipitation and South Asian monsoon related to the Indian Ocean SST.…”

An annual (July to June) precipitation reconstruction for the period AD 1760–2010 was developed from a Picea crassifolia regional tree‐ring chronology from two sites in the northern mountainous region of the Hexi Corridor, NW China. This reconstruction explains 52.1% of the actual precipitation variance during the period 1951 to 2010. Spatial correlations with gridded land‐surface data reveal that our reconstruction contains a strong regional precipitation signal for the Hexi Corridor and for the southern margin of the Badain Jaran Desert. Significant spectral peaks were identified at 31.9, 11.1, 8.0, 7.0, 3.2, 2.6 and 2.2 years. A large‐scale comparison indicates that our reconstruction is more consistent with climate records of a Westerly‐dominated Central Asia, and that the Westerlies have a greater impact on the precipitation in this region than the Asian summer monsoon. Our reconstructed precipitation series is significantly correlated with sea‐surface temperature (SST) in the tropical Atlantic Ocean (positive), the tropical Indian Ocean (positive), the western tropical Pacific Ocean (positive), and the western North Pacific Ocean (negative). The spatial correlation patterns between our precipitation reconstruction and SSTs of the Atlantic and Pacific Oceans suggest a connection between regional precipitation variations and the high‐mid‐latitude northern atmospheric circulations (Westerlies and Asian summer monsoon).
