Abstract The Third Pole (TP) is experiencing rapid warming and currently in its warmest period the past 2,000 years. This paper reviews latest development multidisciplinary TP research associated with this warming. facilitates intense broad glacier melt over most of TP, although some glaciers northwest are advancing. By heating atmosphere reducing snow/ice albedo, aerosols also contribute to melting. Glacier accompanied by lake expansion intensification water cycle TP. Precipitation has...
Abstract Hydrologic cycle intensification is an expected manifestation of a warming climate. Although positive trends in several global average quantities have been reported, no previous studies documented broad across elements the Arctic freshwater (FWC). In this study, authors examine character and quantitative significance changes annual precipitation, evapotranspiration, river discharge terrestrial pan-Arctic over past decades from observations suite coupled general circulation models...
Changes in active layer thickness (ALT) over northern high‐latitude permafrost regions have important impacts on the surface energy balance, hydrologic cycle, carbon exchange between atmosphere and land surface, plant growth, ecosystems as a whole. This study examines 20th century variations of ALT for Ob, Yenisey, Lena River basins. is estimated from historical soil temperature measurements 17 stations (1956–1990, basin only), an annual thawing index based both air data (1901–2002)...
The hydrological regimes for the major river basins in Tibetan Plateau (TP), including source regions of Yellow (UYE), Yangtze (UYA), Mekong (UM), Salween (US), Brahmaputra (UB), and Indus (UI) rivers, were investigated through a land surface model regression analyses between climate variables runoff data. A hydrologic modeling framework was established across TP to link Variable Infiltration Capacity (VIC) hydrology with degree‐day glacier‐melt scheme (VIC‐glacier model) at 1/12° × 1/12°....
Abstract Increased attention directed at the permafrost region has been prompted by resource development and climate change. This review surveys advances in hydrology since 2000. Data shortage data quality remain serious concerns. Yet, there much progress understanding fundamental hydrologic processes operating a wide range of environments, from steep mountainous catchments, to Precambrian Shield with moderate relief, low‐gradient terrain plains, plateaus wetlands. Much recent research...
ABSTRACT The European Centre for Medium‐range Weather Forecasts ( ECMWF ) reanalysis ERA ‐40, ‐Interim, University of Washington UW data, APHRODITE's Water Resources APHRODITE ), and Tropical Rainfall Measuring Mission (TRMM) Multisatellite Precipitation Analysis TMPA precipitation estimates are compared with each other the corrected gauge observations over Tibetan Plateau TP at both basin plateau scales. ‐40 generally can capture broad spatial temporal distributions in gauge‐based ....
Abstract Combining π‐conjugated and non‐π‐conjugated groups is an important strategy for synthesizing new nonlinear optical (NLO) crystals. However, the second harmonic generation (SHG) response anisotropy can be limited by improper spatial alignment of these functional in crystal structure. In this work, it revealed that [NH 2 SO 3 ] group acts as both hydrogen bond donor acceptor, effectively regulating 2D planar structure formed [C 4 N H 6 groups. The resulting organic–inorganic hybrid C...
The long‐term (1935–1999) monthly records of temperature, precipitation, stream flow, river ice thickness, and active layer depth have been analyzed in this study to examine Lena River hydrologic regime recent change. Remarkable changes identified study. During the cold season (October–April), significant increases (25–90%) flow decrease thickness found due warming Siberia. In snowmelt period (May–June), strong spring leads an advance into late May results a lower daily maximum discharge...
A consistent daily bias correction procedure was applied at 4802 stations over high latitude regions (North of 45°N) to quantify the precipitation gauge measurement biases wind‐induced undercatch, wetting losses, and trace amount for last 30 years. These corrections have increased gauge‐measured monthly significantly by up 22 mm winter months, slightly about 5 during summer season. Relatively, factors (CF) are small in (10%), very large (80–120%) because effect wind on undercatch snowfall....
This study systematically analyzes long‐term (1936–1999) monthly discharge records for the major subbasins within Lena River watershed in order to document significant streamflow hydrology changes induced by human activities (particularly reservoirs) and natural variations/changes. The results show that upper streams of watershed, without much impact, experience a runoff increase winter, spring, (particularly) summer seasons decrease fall season. These seasonal characteristics indicate...
Dramatic changes have been observed in the Arctic over last century. Many of these involve storage and cycling fresh water. On land, precipitation river discharge, lake abundance size, glacier area volume, soil moisture, a variety permafrost characteristics changed. In ocean, sea ice thickness areal coverage decreased water mass circulation patterns shifted, changing freshwater pathways cover dynamics. Precipitation onto ocean surface has also Such are expected to continue, perhaps...
We use monthly discharge and permafrost data to examine the relationship between characteristics basin coverage for nested subbasins of Lena River in Siberia. There are similarity variation streamflow regimes over basin. The ratios maximum/minimum flows directly reflect regimes. increase with drainage area from headwaters downstream within This pattern is different nonpermafrost watersheds, it clearly reflects effect on regional hydrological regime. a significant positive ratio coverage....
We assess the correspondence between precipitation products from atmospheric reanalyses (ERA‐40, NCEP‐1, and NCEP‐2), Climate Prediction Center (CPC) Merged Analyses of Precipitation (CMAP‐1 CMAP‐2), Global Climatology Project Version 2 (GPCP‐2) with adjusted observational (AOP) China for 1979–2001 also ERA‐40 NCEP‐1 over 1958–1978. In general, we conclude that CMAP‐1 GPCP‐2 agree more closely AOP than reanalysis do, although data NCEP data. The percentages differences (PPDs) across annual...
An international programme dedicated to the study of Third Pole Environment (TPE) is now developing. The TPE region centred on Tibetan Plateau and concerns interests surrounding countries regions. To improve input for hydrological research, we collected precipitation data 241 meteorological stations across region; these were obtained from various countries, thus including types gauges. Employing procedure recommended by World Meteorological Organization (WMO), a full version bias adjustment...
Abstract. Although precipitation has been measured for many centuries, measurements are still beset with significant inaccuracies. Solid is particularly difficult to measure accurately, and wintertime measurement biases between different observing networks or regions can exceed 100 %. Using gauge results from the World Meteorological Organization Precipitation Intercomparison Experiment (WMO-SPICE), errors in caused by uncertainty, spatial variability precipitation, hydrometeor type, crystal...
ABSTRACT In this paper, we investigate the spatiotemporal characteristics and trends of snow cover fraction (SCF) in Tibetan Plateau (TP) seven upstream river basins (Yellow, Yangtze, Mekong, Salween, Brahmaputra, Indus Yarkant) by employing Moderate Resolution Imaging Spectroradiometer (MODIS) data for 2001–2014. The possible linkage between SCF, temperature precipitation changes over TP individual is also investigated. Results suggest that distribution exhibit a large heterogeneity with...
