Abstract The European CORDEX (EURO-CORDEX) initiative is a large voluntary effort that seeks to advance regional climate and Earth system science in Europe. As part of the World Climate Research Programme (WCRP) - Coordinated Regional Downscaling Experiment (CORDEX), it shares broader goals providing model evaluation projection framework improving communication with both General Circulation Model (GCM) data user communities. EURO-CORDEX oversees design coordination ongoing ensembles...
A global warming of 2 °C relative to pre-industrial climate has been considered as a threshold which society should endeavor remain below, in order limit the dangerous effects anthropogenic change. The possible changes regional under this target level have so far not investigated detail. Using an ensemble 15 simulations downscaling six transient simulations, we identify respective time periods corresponding warming, describe range projected for European and investigate uncertainty across...
Abstract Here we present the first multi-model ensemble of regional climate simulations at kilometer-scale horizontal grid spacing over a decade long period. A total 23 run with $$\sim $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mo>∼</mml:mo> </mml:math> 3 km, driven by ERA-Interim reanalysis, and performed 22 European research groups are analysed. Six different models (RCMs) represented in ensemble. The compared against available high-resolution precipitation...
Abstract. In the current work we present six hindcast WRF (Weather Research and Forecasting model) simulations for EURO-CORDEX (European Coordinated Regional Climate Downscaling Experiment) domain with different configurations in microphysics, convection radiation time period 1990–2008. All regional model are forced by ERA-Interim reanalysis have same spatial resolution (0.44°). These evaluated surface temperature, precipitation, short- longwave downward at total cloud cover. The analysis of...
Abstract The Paris Agreement of the United Nations Framework Convention on Climate Change aims not only at avoiding +2°C warming (and even limit temperature increase further to +1.5°C), but also sets long‐term goals guide mitigation. Therefore, best available science is required inform policymakers importance and adaptation needs in a +1.5°C warmer world. Seven research institutes from Europe Turkey integrated their competencies provide cross‐sectoral assessment potential impacts...
Increasing numbers of scholars and practitioners appeal to procedural theories 'co-production' as they work transform climate science into services. Most in this direction theorises co-production an 'iterative interactive' process between service providers users, with success measured mainly terms the usefulness usability information product for user. But notwithstanding these first important steps, perspective paper argues that current study is too narrowly framed, fails properly engage...
Abstract Interactions between the land surface and atmosphere play a fundamental role in weather climate system. Here we present comparison of summertime land‐atmosphere coupling strength found subset ERA‐Interim‐driven European domain Coordinated Regional Climate Downscaling Experiment (EURO‐CORDEX) model ensemble (1989–2008). Most regional models (RCMs) reproduce overall soil moisture interannual variability, spatial patterns, annual cycles exchange fluxes for different zones suggested by...
Abstract. There is an observed relationship linking Arctic sea ice conditions in autumn to mid-latitude weather the following winter. Of interest this study a hypothesized stratospheric pathway whereby reduced Barents and Kara seas enhances upward wave activity wave-breaking stratosphere, leading weakening of polar vortex transition North Atlantic Oscillation (NAO) its negative phase. The Causal Effect Networks (CEN) framework used explore between late Barents–Kara February NAO, focusing on...
Abstract. It is now well established that the Arctic warming at a faster rate than global average. This warming, which has been accompanied by dramatic decline in sea ice, linked to cooling over Eurasian subcontinent recent decades, most dramatically during period 1998–2012. counter-intuitive impact under given land regions should warm more ocean (and average). Some studies have proposed causal teleconnection from sea-ice retreat wintertime cooling; other argue mainly driven internal...
Abstract As global temperatures continue to rise, the impact of heatwaves becomes increasingly striking. The increasing frequency and intensity these events underscore critical need understand regional‐scale mechanisms feedback, exacerbating or mitigating heatwave magnitude. Here, we use an ensemble convection‐permitting regional climate models (CPRCMs) elucidate future changes at fine spatial scales. We explore whether recently highlighted drier/warmer signal introduced by CPRCMs improves...
Abstract Understanding the present water budget in Himalayan Basins is a challenge due to poor situ coverage, incomplete or unreliable records, and limitations of coarse resolution gridded data set. In study, two‐way coupled implementation Weather Research Forecasting (WRF) Model WRF‐Hydro hydrological modeling extension package (WRF/WRF‐Hydro) was employed its offline configuration, over 10 year simulation period for mountainous river basin North India. A triple nest employed, which...
Abstract Recent studies have indicated the importance of fall climate forcings and teleconnections in influencing northern mid- to high latitudes. Here, we present some exploratory analyses using observational data seasonal hindcasts, with aim highlighting potential El Niño–Southern Oscillation (ENSO) as a driver variability during boreal late early winter (November December) North Atlantic–European sector, motivating further research on this relatively unexplored topic. The atmospheric ENSO...
Extreme weather events represent one of the most visible and immediate hazards to society. Many these types phenomena are projected increase in intensity, duration or frequency as climate warms. Of extreme winds among damaging historically over Europe yet assessments their future changes remain fraught with uncertainty. This uncertainty arises due both rare nature wind fact that model unable faithfully them. Here we take advantage a 15 member ensemble high resolution Euro-CORDEX simulations...
Abstract The Coordinated Regional Downscaling Experiment (CORDEX) is a coordinated international activity that has produced ensembles of regional climate simulations with domains cover all land areas the world. These are used by wide range practitioners include scientific community, policymakers, and stakeholders from public private sectors. They also provide basis for Intergovernmental Panel on Climate Change-Assessment Reports. As its next phase now launches, CMIP6-CORDEX datasets expected...
Abstract The ability of state‐of‐the‐art regional climate models to simulate cyclone activity in the Arctic is assessed based on an ensemble 13 simulations from 11 Arctic‐CORDEX initiative. Some employ large‐scale spectral nudging techniques. Cyclone characteristics simulated by are compared with results forced four reanalyses (ERA‐Interim, National Centers for Environmental Prediction‐Climate Forecast System Reanalysis, Aeronautics and Space Administration‐Modern‐Era Retrospective analysis...
Abstract There is an ongoing debate over whether accelerated Arctic warming [Arctic amplification (AA)] altering the large-scale circulation responsible for anomalous weather experienced by midlatitude regions in recent years. Among proposed mechanisms idea that local processes associated with sea ice loss heat lower troposphere at high latitudes, thus weakening equator-to-pole temperature gradient and driving changes quasi-stationary waves, jets, storm tracks. It further hypothesized these...
Abstract The increase in computational resources has enabled the emergence of multi-model ensembles convection-permitting regional climate model (CPRCM) simulations at very high horizontal resolutions. An example is CORDEX Flagship Pilot Study on “Convective phenomena resolution over Europe and Mediterranean”, a set kilometre-scale an extended Alpine domain. This first-of-its-kind ensemble, forced by ERA-Interim reanalysis, can be considered benchmark dataset. study uses recently proposed...
