Despite the ecological importance of forest tree species, our study was motivated by scarce data on dendrochronology studies limited to the northwestern part of Tajikistan due to lack of access to such a part of the country which is difficult to access. Current studies on Junipers in the northwestern part of Tajikistan identified that tree ring-based climate reconstruction is possible.Cores of Juniperus Turkestanica from Taboshar area, Sogd province were developed into 176-year tree-ring width chronology. In the current study a summer (June-September) minimum temperature reconstruction spanning AD 1840-2016 was developed, which can explain 30.0% of the instrumental variableness for the period of 1940 . Five warmest (1856 -1866 , 1869 -1871 , 1907 -1916 , 1923 -1935 , 1988 and four coldest time periods (1840-1855, 1872-1906, 1917-1922, 1940-1984) were identified. The developed reconstruction coincides with cold and warm periods with prior investigations from tree-rings in China, Mongolia, Kyrgyzstan, Kazakhstan and Tajikistan. Spatial correlation analysis with the gridded minimum temperature data shows that the temperature reconstruction covers geographical representation over High Asia. Significant correlation was found between temperature reconstruction with summer SST, which suggests strong linkages of regional temperature variability with IndianOcean climate system. The obtained spectral peaks from the spectral analysis of the summer temperature reconstruction were significantly at 84.7-year (90%), 2.9-year (99%), 2.6-year (99%), 2.5-year (99%), 2.4-year (99%) and 2.2-year (99%).

“…The mean PDSI value from 1721 to 1723 was −4.39, which is much lower than the mean PDSI value of this reconstruction. This drought was also recorded by a joint investigation based on drought/flood index and tree-ring records in 1720-1722 at Luya Mountain (Yi et al, 2012), which is approximately 700 km north of studied area. The above analysis demonstrated the ability of this PDSI reconstruction to reproduce the drought history in the Lingkong Mountain area, even northern China.…”

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.

“…Significant axes were combined positively for precipitation, and negatively for temperature. As the temperature reconstruction showed considerably lower skill than that for precipitation [48] we only retained the summer precipitation time series in the database. Two proxy datasets were considered regionally consistent and comparable, if they both stem from the South-West-Summer-Monsoon (SWSM) domain, west of 100…”

Warmer and wetter or warmer and dryer? Observed versus simulated covariability of Holocene temperature and rainfall in Asia

Temperatures in Asia, and globally, are very likely to increase with greenhouse gas emissions, but future projections of rainfall are far more uncertain. Here we investigate the linkage between temperature and precipitation in Asia on interannual to multicentennial timescales using instrumental data, late Holocene paleoclimate proxy data and climate model simulations. We find that in the instrumental and proxy data, the relationship between temperature and precipitation is timescale-dependent. While on annual to decadal timescales, negative correlations dominate and thus cool summers tend to be rainy summers, on longer timescales precipitation and temperature are positively correlated; cool centuries tend to be dryer centuries in monsoonal Asia. In contrast, the analyzed CMIP5/PMIP3 climate model simulations show a negative correlation between precipitation and temperature on all timescales. Although many uncertainties exist in the interpretation of the proxy data, there is consistency between them and the instrumental evidence. This, and the persistence of the result across independent proxy datasets, suggests that the climate model simulations might be considerably biased, overestimating the short-term negative associations between regional rainfall and temperature and lacking long-term positive relationships between them.
