We introduce Version 2 of our widely used 1-km Köppen-Geiger climate classification maps for historical and future conditions. The (encompassing 1901-1930, 1931-1960, 1961-1990, 1991-2020) are based on high-resolution, observation-based climatologies, while the 2041-2070 2071-2099) downscaled bias-corrected projections seven shared socio-economic pathways (SSPs). evaluated 67 models from Coupled Model Intercomparison Project phase 6 (CMIP6) kept a subset 42 with most plausible CO2-induced...
Abstract The atmospheric water cycle of the Arctic is evaluated via seven global reanalyses and in radiosonde observations covering 1979–2013 period. In regional moisture budget, evaporation precipitation are least consistent terms among different datasets. Despite assimilation radiosoundings, present a tendency to overestimate transport. Aside from this overestimation, exhibit remarkable agreement with radiosondes spatial temporal patterns. northern North Atlantic, subpolar Pacific,...
Studying glacier mass changes at regional scale provides critical insights into the impact of climate change on glacierized regions, but is impractical using in situ estimates alone due to logistical and human constraints. We present annual mass-balance time series for 239 glaciers European Alps, optical satellite images period 2000-2016. Our approach, called SLA-method, based estimation snowline altitude (SLA) each year combined with geodetic balance over study derive balance. In...
Recent precipitation observations provided by CloudSat are used to evaluate the ability of various meteorological analyses and reanalyses reproduce Antarctic snowfall. The performance ECMWF Interim Re-Analysis (ERA Interim), Climate Forecast System Reanalysis (CFSR), Japanese 55-year (JRA55), Modern Era Retrospective-Analysis for Research Application (MERRA), 2 (MERRA-2), as well operational compared over 2007–2010 period. mean snowfall rate Antarctica north 82 °S simulated between 2007 2010...
Abstract We present in this paper the results of Russian Academy Sciences North Atlantic Atmospheric Downscaling (RAS-NAAD) project, which provides a 40-yr 3D hindcast (10°–80°N) atmosphere at 14-km spatial resolution with 50 levels vertical direction (up to hPa), performed regional setting WRF-ARW 3.8.1 model for period 1979–2018 and forced by ERA-Interim as lateral boundary condition. The dataset variety surface free-atmosphere parameters sigma meets many demands meteorologists, climate...
Abstract The major sources of atmospheric moisture over the Red Sea are analyzed using ERA-Interim for 1979–2013 period. vertical structure transports across coastlines has been computed separately western and eastern coasts Sea. transport from to continents is dominated by a breeze-like circulation in near-surface layer Arabian high above 850 hPa. lower-layer, acting export northwest Africa Peninsula contributes about 80% exports Sea, dominating upper layer, where advected northern part sea...
Abstract. Atmospheric moisture convergence on ice sheets provides an estimate of snow accumulation, which is critical to quantifying sea-level changes. In the case East Antarctica, we computed transport from 1980 2016 in five reanalyses and radiosonde observations. Moisture more consistent than net precipitation but still ranges 72 96 mm yr−1 four most recent reanalyses, ERA-Interim, NCEP CFSR, JRA 55 MERRA 2. The representation long-term variability also inconsistent, justified resorting...
Abstract The Arabian Peninsula, a predominantly hyperarid region, is facing increasing demands for fresh water driven by its growing population. pressure on the resource would be reduced if local evaporation led to more rainfall within domain. This study assesses moisture recycling in region evaluating transport, precipitation, and four state-of-the-art reanalyses against situ remote sensing data. reliably capture main spatial temporal features of particular two-layered structure. upper...

Abstract In this study, we analyse fast (within 30 days) response of the atmospheric rivers and storm tracks positioning over western European coast to Sudden Stratospheric Warming (SSW) events. Analysis is done on basis North Atlantic Atmospheric Downscaling (NAAD) product with 14 km 3-hourly spatial temporal resolutions. cyclones are synoptic phenomena characterized by strong impact onto mid- high latitude costal zones. This results in extreme precipitation wind events, floodings, long wet...
Growing forests is an effective way of removing CO2 from the atmosphere. Forestation projects were started in China, Germany, and Middle East. Saudi Arabia announced its ambitious “Saudi Green Initiative,” intending to plant ten billion trees. Given insufficient rainfall support initiative, vegetated areas will require irrigation, effectively increasing evaporation. In addition, those have a lower albedo than bare land, absorbing more solar radiation. Enhancing...
