    Abstract To explore the history of the changes in monsoon precipitation and their driving mechanisms in the context of global warming, climatology studies using tree-ring stable oxygen isotopes (δ 18 O) were carried out in Shanxi Province, China. Based on a tree-ring δ 18 O series from Pinus tabulaeformis Carr . on Heng Mountain, a 230-year June–July precipitation sequence from 1784 to 2013 AD was reconstructed that explained 45% of the total variance (44% after adjusting the degrees of freedom). The reconstructed sequence captured the characteristics of the variations in precipitation. Periods of drought occurred mainly in 1820–1840 AD, 1855–1865 AD, 1895–1910 AD, 1925–1930 AD, and 1970–1995 AD, and wet periods occurred mainly in 1880–1895 AD, 1910–1925 AD, and 1935–1960 AD. The dry and wet years in the precipitation reconstruction corresponded well to the years in which disaster events were documented in historical records. A spatial correlation analysis with Climatic Research Unit (CRU)-gridded precipitation data indicated that the reconstructed precipitation provided good regional representation and reflected large-scale June–July precipitation changes in northern China. In addition, the reconstructed precipitation sequence was also significantly correlated with the dry and wet index (DWI) and other tree-ring dry/wet reconstructions from the surrounding areas. The correlation between the reconstructed precipitation and the Asian monsoon index showed that the precipitation can indicate the intensity of the Asian summer monsoon. Moreover, a significant negative correlation was found between the El Niño–Southern Oscillation (ENSO) and the reconstructed precipitation. At the decadal scale, the negative phase of the Pacific Decadal Oscillation (PDO) and the positive phase of the Atlantic Multidecadal Oscillation (AMO) may co-promote summer precipitation in the study area.

    Abstract The inter-annual stable carbon isotope ratio (δ 13 C) of three tree-ring cores of P. euphratica ( Populus euphratica Oliv.) was determined from Ejina Oasis in Northwest China. A robust and representative δ 13 C chronology is generated from the three δ 13 C series using an arithmetic mean method. After eliminating the influence of the δ 13 C from elevated atmospheric carbon dioxide (CO 2 ) concentration, we obtained a carbon isotopic discrimination (Δ 13 C) chronology. According to the significant correlation between the tree-ring Δ 13 C and instrumental data, we reconstructed the mean maximum temperature anomalies from previous December to current September (T DS ) for the period 1901–2011. The reconstruction explained 43.6% of the variance over the calibration period. Three high-temperature periods (1929–1965, 1972–1974, and 1992–2006) and three low-temperature periods (1906–1926, 1966–1968, and 1975–1991) were found in the reconstructed series. Comparisons between the reconstructed T DS and the observed mean temperature from previous December to current September in Anxi meteorological station and the temperature index in north-central China demonstrated the reconstructed T DS has the advantage of reliability and stability. The significant spatial correlation declared that the reconstruction has a broad spatial representation and can represent the temperature variation characteristics in a wide geographical area. In addition, we found that the area of Ejina Oasis is smaller (larger) when the mean maximum temperature is higher (lower), which may be due to a conjunction effect of natural and anthropogenic activities. Significant periodicities and correlations suggested that the T DS variations in Ejina Oasis were regulated by solar radiation and atmospheric circulations at the interannual and interdecadal time scales.

    Abstract A comprehensive understanding of the spatial characteristics of warming trends and temperature variability is important given global warming. Paleoclimate reconstruction has played an important role in evaluating warming and extreme climactic events in recent decades. Using the ring width of Pinus tabulaeformis , we reconstructed the ground surface temperature changes at Mengshan Mountain, in the central part of eastern China (EC), from 1667 to 2019. There were 3 extremely low-temperature years, 42 low-temperature years, 256 normal years, 37 high-temperature years and 15 extremely high-temperature years over the past 353 years. High and extremely high temperatures mainly occurred in the first half of the 19th century, the end of the 20th century and the beginning of the 21st century; low and extremely low temperatures occurred in almost all periods except for the last 50 years. By combining the past temperature reconstructions from the Great Xing’an Mountains in northern EC and Taiwan in southern EC, we also found that after the start of the Anthropocene, there were strong positive correlations among the temperatures of the northern, central and southern parts of EC. However, before the Anthropocene, these correlations were weak, and there was even a significant negative correlation during some periods. Additionally, the temperature in EC exhibited different change patterns before and during the Anthropocene. Before the Anthropocene, the temperature in southern EC showed an upward trend; in central EC, the temperature first rose and then began to decline in the 1820s; there was no obvious trend in the temperature changes in northern EC. The spatial consistency of temperature changes during the Anthropocene might be related to the fact that greenhouse gases emitted by human activities diffuse evenly withatmospheric circulation and absorb longwave radiation to directly heat the atmosphere.

    Abstract Under the background of global climate change, arid to semi-humid areas are more vulnerable to extreme climate, such as floods and droughts. To better predict and cope with future climate change, more local and regional long-term high-resolution climate reconstructions, hydroclimate in particular, are required. Based on a 174-year regional tree-ring-width chronology, we reconstructed the February–June Standardized Precipitation Evapotranspiration Index (SPEI26) history in the Lüliang Mountains, North China (NC). Reconstructed SPEI26 is expected to reflect the dry-wet variation from spring to early summer (STES) of NC with an explained variance of 43.8% for the instrumental record (1951–2007 CE). The reconstruction reveals three comparatively dry (1857–1878, 1919–1929 and 1995–2001 CE) and four comparatively wet (1883–1895, 1934–1944, 1952–1961 and 1980–1984 CE) periods during 1834–2007 CE. Although a drying trend is seen since the 1950s, an advent of wetting since the end of the 1990s is expected. As the driest period in the reconstruction, 1919–1929 CE records the widespread catastrophic 1920s drought in northern China. In addition to the local hydroclimatic signal, the reconstruction also reflects hydroclimatic variation over a large portion of northern China, which is evidented by the comparison with other hydroclimatic records and regional dry-wet index. Strength of the Indian summer monsoon and the East Asian summer monsoon in the previous year play vital roles in the STES dry-wet variations. Moreover, Atlantic Multi-decadal Oscillation index influencs the hydroclimate in NC by influencing the Asian summer monsoon system.

    Abstract Vegetation coverage is very important in terrestrial ecosystems and climate systems. However, the observational record of the normalized difference vegetation index (NDVI), which started in the 1980s when satellites became widely used, is too short to investigate the history of variation in vegetation coverage beyond the modern observation period. Here, we present a 189 y vegetation coverage series based on a total of 349 Mongolian pine ( Pinus sylvestris var. mongolica Litv) cores from seven locations from the central–western Da Hinggan Mountains (CW–DHM), northeastern China. We found a significant relationship between tree-ring width and the regional cumulative normalized difference vegetation index (CNDVI). The correlation between the ring-width chronology and the regional June–July CNDVI ( CNDVI JJ ) was significant, with r = 0.68 ( n = 32, p < 0.001) and an explained variance of 45.8% (44.0% after the adjustment for the loss of the degree of freedom). On this basis, we designed a transfer function to reconstruct the CNDVI JJ for the CW–DHM region from 1825 to 2013 CE (Common Era). During the last 189 years, there were 28 years with high CNDVI JJ values, and another 28 years with low values. We also observed CNDVI JJ fluctuations at the inter-annual and decadal time scales, including eight low value periods and nine high value periods. Based on our analysis, the variation in CNDVI is associated with climatic factors, such as temperature, precipitation and the Palmer Drought Severity Index (PDSI), which combines both temperature and precipitation. From 1950 to 2002 CE, the CNDVI showed a noticeable decreasing trend in the CW–DHM region, whereas after 2003 CE, the CNDVI exhibited an apparent increase, which has also been observed in southern Central Siberia, eastern Mongolia and northeastern and eastern China, indicating that the CNDVI change in the CW–DHM is related to climate change in the local region and in some parts of Asia.

    Abstract The historical May-October mean temperature since 1831 was reconstructed based on tree-ring width of Qinghai spruce (Picea crassifolia Kom.) collected on Mt. Dongda, North of the Hexi Corridor in Northwest China. The regression model explained 46.6% of the variance of the instrumentally observed temperature. The cold periods in the reconstruction were 1831-1889, 1894-1901, 1908-1934 and 1950-1952, and the warm periods were 1890-1893, 1902-1907, 1935-1949 and 1953-2011. During the instrumental period (1951-2011), an obvious warming trend appeared in the last twenty years. The reconstruction displayed similar patterns to a temperature reconstruction from the east-central Tibetan Plateau at the inter-decadal timescale, indicating that the temperature reconstruction in this study was a reliable proxy for Northwest China. It was also found that the reconstruction series had good consistency with the Northern Hemisphere temperature at a decadal timescale. Multi-taper method spectral analysis detected some low- and high-frequency cycles (2.3-2.4-year, 2.8-year, 3.4-3.6-year, 5.0-year, 9.9-year and 27.0-year). Combining these cycles, the relationship of the low-frequency change with the Pacific Decadal Oscillation (PDO), North Atlantic Oscillation (NAO) and Southern Oscillation (SO) suggested that the reconstructed temperature variations may be related to large-scale atmospheric-oceanic variations. Major volcanic eruptions were partly reflected in the reconstructed temperatures after high-pass filtering; these events promoted anomalous cooling in this region. The results of this study not only provide new information for assessing the long-term temperature changes in the Hexi Corridor of Northwest China, but also further demonstrate the effects of large-scale atmospheric-oceanic circulation on climate change in Northwest China.

    Abstract In order to further understand the past climate variation especially the history of drought and flood events in the East Asian summer monsoon (EASM) marginal area, precipitation from previous August to current July for the period of 1805–2014 AD was reconstructed from a ring-width chronology of Pinus tabulaeformis in Zhaogaoguan (ZGG), a site located in the EASM marginal area in northern China. The transfer function can explain 46.4% (adjusted to 45.4% for the loss of degrees of freedom) of the variance of the observed precipitation during the calibration period (1958–2014 AD). The reconstructed precipitation series revealed that the inter-annual variability was very prominent; 1843 and 1844 AD were the two wettest years, while 1931 and 1999 AD were the two driest years. We noticed that the droughts in 1900, 1906, 1931, 1955 and 1999 AD in the reconstruction series corresponded to the severe floods in the Yangtze River watershed in southern China during those same years. This phenomenon confirmed the typical climate pattern of northern droughts and southern floods in China. Moreover, the reconstructed precipitation series in ZGG showed synchronous variation patterns with the other tree-ring-based hydrological reconstructions in the marginal area of EASM on both inter-annual and inter-decadal scales, indicating the common precipitation variation characteristics of the EASM marginal area.

    Abstract Sunshine is as essential as temperature and precipitation for tree growth, but sunshine duration reconstructions based on tree rings have not yet been conducted in China. In this study, we presented a 497-year sunshine duration reconstruction for the southeastern Tibetan Plateau using a width chronology of Abies forrestii from the central Hengduan Mountains. The reconstruction accounted for 53.5% of the variance in the observed sunshine during the period of 1961–2013 based on a stable and reliable linear regression. This reconstructed sunshine duration contained six sunny periods (1630–1656, 1665–1697, 1731–1781, 1793–1836, 1862–1895 and 1910–1992) and seven cloudy periods (1522–1629, 1657–1664, 1698–1730, 1782–1792, 1837–1861, 1896–1909 and 1993–2008) at a low-frequency scale. There was an increasing trend from the 16th century to the late 18th and early 19th centuries and a decreasing trend from the mid-19th to the early 21st centuries. Sunshine displayed inverse patterns to the local Palmer drought severity index on a multidecadal scale, indicating that this region likely experienced droughts under more sunshine conditions. The decrease in sunshine particularly in recent decades was mainly due to increasing atmospheric anthropogenic aerosols. In terms of the interannual variations in sunshine, weak sunshine years matched well with years of major volcanic eruptions. The significant cycles of the 2- to 7-year, 20.0-year and 35.2-year durations as well as the 60.2-year and 78.7-year durations related to the El-Niño Southern Oscillation, the Pacific Decadal Oscillation and the Atlantic Multidecadal Oscillation suggested that the variation in sunshine duration in the southeastern Tibetan Plateau was possibly affected by large-scale ocean-atmosphere circulations.

    Abstract A tree-ring-width chronology was developed from Pinus tabulaeformis aged up to 333 years from central Inner Mongolia, China. The chronology was significantly correlated with the local Palmer Drought Severity Index (PDSI). We therefore reconstructed the first PDSI reconstruction from March to June based on the local tree ring data from 1680 to 2012 AD. The reconstruction explained 40.7 % of the variance (39.7 % after adjusted the degrees of freedom) of the actual PDSI during the calibration period (1951–2012 AD). The reconstructed PDSI series captured the severe drought event of the late 1920s, which occurred extensively in northern China. Running variance analyses indicated that the variability of drought increased sharply after 1960, indicating more drought years, which may imply anthropogenic related global warming effects in the region. In the entire reconstruction, there were five dry periods: 1730–1814 AD, 1849–1869 AD, 1886–1942 AD (including severe drought in late 1920s), 1963–1978 AD and 2004–2007 AD; and five wet periods: 1685–1729 AD, 1815–1848 AD, 1870–1885 AD, 1943–1962 AD and 1979–2003 AD. Conditions turned dry after 2003 AD, and the PDSI from March to June (PDSI₃₆) captured many interannual extreme drought events since then, such as 2005–2008 AD. The reconstruction is comparable to other tree-ring-width-based PDSI series from the neighboring regions, indicating that our reconstruction has good regional representativeness. Significant relationships were found between our PDSI reconstruction and the solar radiation cycle and the sun spot cycle, North Atlantic Oscillation, the El Niño-Southern Oscillation, as well as the Pacific Decadal Oscillation. Power spectral analyses detected 147.0-, 128.2-, 46.5-, 6.5-, 6.3-, 2.6-, 2.2- and 2.0-year quasi-cycles in the reconstructed series.

    Abstract KEY MESSAGE: This paper provides the first interannual variability of PDSI series in Central Inner Mongolia, China. A Pinus tabulaeformis tree-ring-width chronology in Baotou, China, was developed. Based on the chronology, we reconstructed the local interannual variability of the Palmer Drought Severity Index (PDSI) from the previous September to current July (PDSIₚ₉–₇) for the past 278 years. The reconstruction explained 41.3% of the variance (40.3% after adjusting the degrees of freedom) of the actual interannual variability of the PDSI during the calibration period (1951–2012 AD). The spectral analyses revealed 3.5-, 2.6-, 2.3-, 2.1- and 2-year quasi-cycles at a 95% confidence level and 7.9-, 7.1- and 5.2-year quasi-cycles at a 90% confidence level. The PDSI reconstruction series was consistent with several reconstructed climatic series based on the tree-ring chronology in neighboring regions. The PDSIₚ₉–₇ exhibits excellent regional representativeness, which indicates the consistency of the drought variation of the central part of the monsoon margin area in north China, whereas PDSIₚ₉–₇ can represent the drought history of the central part of the north monsoon margin area. In addition, significant relationships were found between the PDSIₚ₉–₇ series and the Arctic Oscillation, North Atlantic Oscillation, El Niño-Southern Oscillation and Pacific Decadal Oscillation series, which indicates that the PDSI variation in the study area was influenced by a combination of these factors.
