A Mt. Everest ice core spanning 1860–2000 AD and analyzed at high resolution for black carbon (BC) using a Single Particle Soot Photometer (SP2) demonstrates strong seasonality, with peak concentrations during the winter-spring, low summer monsoon season. BC from 1975–2000 relative to 1860–1975 have increased approximately threefold, indicating that anthropogenic sources is being transported elevation regions of Himalaya. The timing increase in consistent emission inventory data South Asia...
Abstract. A continuous measurement for black carbon (hereafter "BC") in a 40 m shallow ice core retrieved from the East Rongbuk Glacier "ERG") northeast saddle of Mt. Qomolangma (Everest) provided first historical record BC deposition during past ~50 yrs high Himalyas. Apparent increasing trend (smooth average) concentrations was revealed since mid-1990s. Seasonal variability indicated higher monsoon seasons than those non-monsoon seasons. Backward air trajectory analysis by HYSPLIT model...
Abstract Stakes at 2 km intervals were installed in January 1997 and remeasured February 1998, 1999, 2005 during the 2007/08 austral summer along a 1248 traverse route from Zhongshan station to Dome A, East Antarctica. Based on topographical parameters, meteorological features records of ∼650 stakes six stake arrays, is divided into five zones. We find that snow accumulation rate decreases with increasing altitude as one progresses inland, except zone 800–1128 coast, where average annual...
Abstract Near-surface wind speed observations from 30 manned meteorological stations and 26 automatic weather over the Antarctic Ice Sheet are used to examine robustness of climatology in six recent global reanalysis products: Modern-Era Retrospective Analysis for Research Applications, version 2 (MERRA-2), Japan Meteorological Agency 55-Year Reanalysis (JRA-55), Climate Forecast System (CFSR), National Centers Environmental Prediction–U.S. Department Energy (DOE) (NCEP2), European Centre...
Abstract Annual-layer thickness data, spanning AD 1534–2001, from an ice core East Rongbuk Col on Qomolangma (Mount Everest, Himalaya) yield age–depth profile that deviates systematically a constant accumulation-rate analytical model. The clearly shows the mean accumulation rate has changed every 50–100 years. A numerical model was developed to determine magnitude of these multi-decadal-scale rates. used obtain time series annual accumulation. decreased ∼0.8 m equivalent in 1500s ∼0.3...
A highly resolved Mt. Everest ice core reveals a decrease in marine and increase continental air masses related to relatively high summer surface pressure over Mongolia, reduction northward incursions of the South Asian monsoon since ∼1400 AD. Previously published proxy records from lower sites south Himalayas indicate strengthening this time. These regional differences are consistent with south–north seesaw convective activity region, reflect southward shift mean position trough The change...
Abstract. In the Asian monsoon region, variations in stable isotopic composition of speleothems have often been attributed to "amount effect". However, an increasing number studies suggest that effect" local precipitation is insignificant or even non-existent. To explore this issue further, we examined variability daily (δ18O) from September 2011 November 2014 Nanjing, eastern China. We found intra-seasonal δ18O during summer were not significantly correlated with rainfall amount but could...
Abstract Local moisture recycling plays an essential role in maintaining active hydrological cycle of the Tibetan Plateau (TP). Previous studies were largely limited to seasonal time scale due short and sparse observations, especially for northwestern TP. In this study, we used a two‐component mixing model estimate local over past decades from deuterium excess records two ice cores (i.e., Chongce Zangser Kangri) The results show that on average almost half precipitation TP is provided by...
Abstract The reasons for the Holocene temperature conundrum, known as inconsistency between reconstructed cooling and inferred warming simulations during Holocene, remain unclear. Temperature reconstructions from Tibetan Plateau (TP) provide important insights understanding conundrum due to enhanced sensitivity climate at high altitudes. Given significant positive correlation air δ 18 O in precipitation over northern TP, stable isotopic records of ice cores recovered this area are widely...
The edge of a monsoon region is usually highly sensitive to climate change. Pakistan, which located on the northern Indian monsoon, vulnerable heavy rainfall and has witnessed several debilitating floods exacerbated by global warming in recent years. However, mechanisms for frequent Pakistan are yet not fully understood. Here, we show that Middle East undergoing an increase land heating during spring, responsible 46% intensified over northwestern India 1979-2022. This springtime causes...
High‐resolution major and trace elements (Sr, Cs, Ba, La, Ce, Pr, Nd, Sm, Eu, Tb, Dy, Ho, Er, Tm, Yb, Lu, Bi, U, Tl, Al, S, Ca, Ti, V, Cr, Mn, Fe, Co) quantified in a Mount Everest ice core (6518 m above sea level) spanning the period 1650–2002 AD provides first Asian record of element concentrations from pre‐industrial era, continuous high‐resolution which natural baseline subsequent changes due to anthropogenic activities can be examined. Modern most remain within range; however, Cs their...
As, Mo, Sn, and Sb have been determined by inductively coupled plasma sector field mass spectrometry (ICP-SFMS) in 143 depth intervals of high-altitude ice cores from Mt. Everest, covering an 800-year time period 1205 to 2002 AD. The results clearly demonstrate the long-term historical record atmospheric transport deposition that has prevailed at high altitudes central Himalayas. Natural contributions, mainly mineral dust, dominated cycles some extent during 700 years prior 20th century....
Abstract. Several ice cores have been recovered from the Dasuopu (DSP) Glacier and East Rongbuk (ER) in central Himalayas since 1990s. Although distance between DSP ER core drilling sites is only ~ 125 km, stable isotopic record (δ18O or δD) of interpreted previous studies as a temperature proxy, while precipitation proxy. Thus, climatological significance records these Himalayan remains subject debate. Based on analysis regional patterns over region, we find that remarkable discrepancy...
Abstract. An accurate chronology is the essential first step for a sound understanding of ice core records. However, dating cores drilled from high-elevation glaciers challenging and often problematic, leading to great uncertainties. The Guliya core, bedrock (308.6 m in length) along western Kunlun Mountains on north-western Tibetan Plateau (TP) widely used as benchmark palaeoclimate research, believed reach >500 ka (thousand years) at its bottom. Meanwhile other (i.e. Dasuopu East...
Abstract Long‐term continuous monitoring of water vapor isotopes has great potential to improve our understanding mechanisms that control stable isotope variations in hydrological processes, which is essential for accurate interpretation isotopic proxy records. Here we presented a 6‐year daily data set atmospheric ( δ 18 O v , D and d ‐excess ) precipitation p at Nanjing Eastern China, an area under the influence East Asian Monsoon. Based on variations, divided year into three seasons, is,...
Abstract. In the East Asian monsoon region, winter extreme precipitation events occasionally occur and bring great social economic losses. From December 2018 to February 2019, southeastern China experienced a record-breaking number of events. this study, we analyzed variation in water vapor isotopes their controlling factors during Nanjing, China. The results show that variations are closely linked change moisture sources. Using d-excess-weighted trajectory model, identified following five...
