“…For example, the cold periods during approximately the AD 840s and 910s can be seen in a stalagmite series from Beijing (Tan et al, 2003) and in historical documents from eastern China (Ge et al, 2003). The warm periods during approximately the AD 1240s, 1540s and 1990s were recorded both in eastern China and in the TP (Yang et al, 2002(Yang et al, , 2009b. These agreements not only suggested the occurrence of climatic events at a continental or even semi-hemispheric scale but also reinforced the validity of our temperature reconstruction.…”

“…Such discrepancies seem to be a common problem in tree-ring-based temperature reconstructions in China, in which the agreement between observed data and estimated data became worse before the 1990s in many regions across China (Deng et al, 2013;Fan et al, , 2010Gou et al, 2007b;Lv and Zhang, 2013;Shi et al, 2010;Song et al, 2014;Yang et al, 2009bYang et al, , 2010Zhang et al, 2013;Zhu et al, 2011a).

Abstract.A 1343-year tree-ring chronology was developed from Qilian junipers in the central Qilian Mountains of the northeastern Tibetan Plateau (TP), China. The climatic implications of this chronology were investigated using simple correlation, partial correlation and response function analyses. The chronology was significantly positively correlated with temperature variables prior to and during the growing season, especially with monthly minimum temperature. Minimum temperature anomalies from January to August since AD 670 were then reconstructed based on the treering chronology. The reconstruction explained 58 % of the variance in the instrumental temperature records during the calibration period and captured the variation patterns in minimum temperature at the annual to centennial timescales over the past millennium. The most recent 50 years were the warmest period, while 1690-1880 was the coldest period since AD 670. Comparisons with other temperature series from neighbouring regions and for the Northern Hemisphere as a whole supported the validity of our reconstruction and suggested that it provided a good regional representation of temperature change in the northeastern Tibetan Plateau. The results of wavelet analysis showed the occurrence of significant quasi-periodic patterns at a number of recurring periods (2-4, 40-50, and 90-170 years), which were consistent with those associated with El Niño-Southern Oscillation (ENSO), Pacific Decadal Oscillation (PDO) and solar activity. The comparison between the reconstructed temperature and the index of tropical volcanic radiative forcing indicated that some cold events recorded by tree rings may be due to the impact of tropical volcanic eruptions.

“…This was also confirmed by a spectral analysis (Morlet mother wavelet), which detected two significant temperature increase trends (marked by rectangles in Figure 3B 2 ). The comparison with temperature proxy records collected in the southeast TP area by Yang et al (2009) adds further confirmation to our temperature reconstruction shown in Figure 3B 1 . The reconstruction performed by these authors also shows a significant warming trend after the 1950s.…”

ABSTRACT:We study the interdecadal-scale variability over the Himalayas/Tibetan Plateau (H/TP) to deepen the understanding of Earth's important ecosystem after the recent controversy about glaciers melting in the Himalayan Mountains. We present a new statistical reconstruction of annual temperature variability back to 1901 for the Pyramid Automated Weather Station of the Ev-K2-CNR Committee, located at the base of the Mount Everest. Our reconstruction using recorded weather station data compared with the Climate Research Unit temperature pattern data indicate that in recent decades the warming trend over the H/TP has been faster than during any equivalent period in the last century. Positive temperature anomalies (mostly observed after 1970) were found to be correlated with the Atlantic Multidecadal Oscillation and the Pacifical Decadal Oscillation indices, but unevenly correlated with the Northern Hemisphere (NH) land-surface temperature. Such decoupled response between H/TP and NH suggests the mechanisms of global warming are only marginally influencing the H/TP climate.

“…Annually dated tree rings are preferable climatic proxies for extending the limited modern meteorological record by analysing the relationship between tree-ring indexes and climatic factors, thereby reconstructing the climate history for centuries to millennia (Zhang et al, 2003;Yang et al, 2009;Zhu et al, 2009;Linderholm et al, 2010;Büntgen et al, 2011;Ohyama et al, 2013). Tree rings have been successfully used to investigate drought history throughout the world (Esper et al, 2007;Cook et al, 2010), including arid to semi-arid areas of China (Liang et al, 2006;Chen et al, 2011a;Fang et al, 2012;.…”

Reconstruction of the March–August PDSI since 1703 AD based on tree rings of Chinese pine (<i>Pinus tabulaeformis</i> Carr.) in the Lingkong Mountain, southeast Chinese loess Plateau

Abstract. We utilised tree-ring cores, collected from three sites at Lingkong Mountain located in the southeast part of the Chinese Loess Plateau (CLP), to develope a regional ring-width chronology. Significant positive correlations between the tree-ring index and the monthly Palmer drought severity index (PDSI) were identified, indicating that the radial growth of trees in this region was moisture-limited. The March-August mean PDSI was quantitatively reconstructed from 1703 to 2008 with an explained variance of 46.4 %. Seven dry periods during 1719-1726, 1742-1748, 1771-1778, 1807-1818, 1832-1848, 1867-1932 and 1993-2008 and six wet periods during 1727-1741, 1751-1757, 1779-1787, 1797-1805, 1853-1864 and 1934-1957 were revealed in our reconstruction. Among them, 1867Among them, -1932Among them, and 1934Among them, -1957 were identified as the longest dry and wet periods, respectively. On the centennial scale, the 19th century was recognised as the driest century. The drying tendency since 1960s was evident. However, recent drought in 1993-2008 was still within the frame of natural climate variability based on the 306 yr PDSI reconstruction. The dry and wet phases of Lingkong Mountain were in accordance with changes in the summer Asian-Pacific oscillation (I APO ) and sunspot numbers, they also showed strong similarity to other tree-ring based moisture indexes in large areas in and around the CLP, indicating the moisture variability in the CLP was almost synchronous and closely related with largescale land-ocean-atmospheric circulation and solar activity. Spatial correlation analysis suggested that this PDSI reconstruction could represent the moisture variations for most parts of the CLP, and even larger area of northern China and east Mongolia. Multi-taper spectral analysis revealed significant cycles at the inter-annual (2-7 yr), inter-decadal (37.9 yr) and centennial (102 yr) scales. Results of this study are very helpful for us to improve the knowledge of past climate change in the CLP and enable us to prevent and manage future natural disasters.
