Different forms of precipitation (snow, sleet, and rain) have divergent effects on the Earth's surface water energy fluxes. Therefore, discriminating between these forms, exploring their climatology variations are significant importance, especially under a changing climate. In this study, state-of-the-art parameterization scheme with wet-bulb temperature (Tw), relative humidity (RH), air pressure, elevation as inputs was used to estimate climatologies trends different thresholds across China...
This paper gives an overview of the current understanding observations black carbon (BC) in snow and ice, estimates BC deposition its radiative forcing over Arctic. Both model results show that, spring, average concentration resulting Russian Arctic > Canadian Alaskan Ocean Greenland. The observed presented a significant decrease trend from coastal regions to center Ocean. In summer, due combined effects accumulation enlarged grain size, averaged per unit area is larger than that each sector...
Abstract. Rain-on-snow (ROS) events can accelerate the surface ablation of sea ice, thus greatly influencing ice–albedo feedback. However, variability ROS over Arctic Ocean is poorly understood due to limited historical station data in this region. In study early melt season were investigated based on four widely used reanalysis products (ERA-Interim, JRA-55, MERRA, and ERA5) conjunction with available observations at coastal stations. The performance representing timing phase change...
Abstract. In this study, we evaluate the ability of latest NASA GISS composition-climate model, GISS-E2-PUCCINI, to simulate spatial distribution snow BC (sBC) in Arctic relative present-day observations. Radiative forcing due deposition onto and sea ice is also estimated. Two sets model simulations are analyzed, where meteorology linearly relaxed towards National Centers for Environmental Prediction (NCEP) Modern Era Reanalysis Research Applications (MERRA) reanalyses. Results indicate that...
Under the effect of global warming, more precipitation will shift to rainfall in cryospheric regions. Considering influence type on surface energy and mass cycles, it is important determine specific features classify key areas correctly. We analyzed monthly distribution, variations each type’s annual days, trends based daily air temperature observations from six tripolar stations. The results indicated that snow dominated at Zhongshan station (69.4°S, 76.4°E) throughout year, while Greatwall...
Shipping volumes in the Northwest Passage are likely to increase under climate change due distance advantage over traditional routes and special strategic location of Arctic. However, harsh environment poor channel conditions may pose a considerable risk ship navigation. To ensure safety ships, understand navigability route, plan sustainable use Passage, it is crucial provide quantitative assessment. Here, we present an analysis several natural risks faced by ships based on available...
Abstract. Snow plays an important role in the Arctic climate system, modulating heat transfer terrestrial and marine environments controlling feedbacks. Changes snow depth over sea ice, particularly spring, have a strong impact on surface energy budget, influencing ocean loss, ice growth ponding. conditions are sensitive to phase (solid or liquid) of deposited precipitation. However, variability potential trends rain-on-snow events their sea-ice losses poorly understood. Time series...
Dissolved organic carbon (DOC) plays an important role in the cycle, radiative forcing, and biogeochemistry cryospheric regions. In this study, concentrations, light-absorption properties bioavailability of DOC from snow cover Alaska were characterized. Results indicated that average concentrations (0.17 − 0.30 mg L<sup>−1</sup>) lower than found Asian mountainous glaciers, but higher polar regions snow. No significant trend was observed during April to May 2017 due short term study; while...
Abstract The changes in the Arctic precipitation profoundly impact surface mass balance of ice sheet and sea ice, extent snow cover, as well land/ice runoff Arctic, particularly when it occurs liquid form. Here, we use state‐of‐the‐art models from Coupled Model Intercomparison Project Phase 5 to project number days with rainfall, intensities onset dates rainfall events under strong emission scenario (RCP8.5). multi‐model mean shows that will occur more frequently at end this century...
<title>Abstract</title> Ice in the atmosphere plays an important role climate system by regulating cloud radiative effects, large-scale circulations, and precipitation processes. The change ice phase with global warming, however, is still unclear. Here we show that, while total mass of atmospheric has remained relatively stable based on satellite measurements since 2000s, spatial distribution may have been changing. This view supported ensemble high-resolution model simulations tropics that...
Gridded surface air temperature (SAT) data for Antarctica is a crucial foundation studying climate change in the region. However, significant discrepancies exist between available Antarctic gridded datasets, particularly regarding spatial distribution characteristics of long-term trends. In this paper, we develop new, regularly updated, spatio-temporally complete monthly SAT dataset from 1979 onwards, with resolution 1° x latitude and longitude, multiple sources situ observations using deep...
Abstract As sea ice becomes thinner and more fragile, it may affect the Arctic Ocean methane budgets in winter. Using satellite, situ reanalysis data, oceanic emissions of over Chukchi Sea coast from 2003 to 2023 are investigated. In total, 196 ventilation days were recorded, contributing atmospheric increases by 15.7 ppb d −1 . Methane is dominated opening greatly enhanced coastal upwelling‐induced mixing. The concentration 5.5[3.3, 7.8] with every 10% decrease concentration. average...
Abstract Extreme sea levels (ESLs) due to typhoon-induced storm surge threaten the societal security of densely populated coastal China. Uncertainty in extreme value analysis (EVA) for ESL estimation has large implications communities’ adaptation natural hazards. Here we evaluate uncertainties and relevant driving factors based on hourly observations from 13 tide gauge stations a complementary dataset derived hydrodynamic model. Results indicate significant estimations stemming using...
Based on daily minimum, maximum, and mean surface air temperatures (T min, T max, mean) from the European Centre for Medium-Range Weather Forecast's reanalysis 1979 onwards (ERA Interim), accuracy of min max is assessed against in situ observations four automatic weather stations (Zhongshan, EAGLE, LGB69, Dome A) East Antarctica 2005 to 2008. ERA Interim generally shows a warm bias cool with an underestimation diurnal temperature range. The explains more than 84% annual variance, replicating...
Abstract The sensitivity of the Arctic precipitation phases (solid and liquid) to forcings from greenhouse gases (GHGs) aerosols over 2016–2080 was investigated by using Community Earth System Model Version 1. Results show that warming caused two results in an increasing trend total a solid‐to‐liquid transition Arctic. Under RCP8.5 scenario, increased rate mean with global forced aerosol reduction (7.7%/°C) is twice greater than GHG emission (3.5%/°C). rainfall ratio (RPR) various much...
