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...
In the framework of EURO-CORDEX initiative an ensemble European-wide high-resolution regional climate simulations on a $$0.11^{\circ }\,({\sim}12.5\,\hbox {km})$$ grid has been generated. This study investigates whether fine-gridded models are found to add value simulated mean and extreme daily sub-daily precipitation compared their coarser-gridded $$0.44^{\circ }\,({\sim}50\,\hbox counterparts. Therefore, pairs fine- coarse-gridded eight reanalysis-driven observations in Alps, Germany,...
In this study the added value of a ensemble convection permitting climate simulations (CPCSs) compared to coarser gridded is investigated. The consists three non hydrostatic regional models providing five with ~10 and ~3 km (CPCS) horizontal grid spacing each. simulated temperature, precipitation, relative humidity, global radiation fields are evaluated within two seasons (JJA 2007 DJF 2007–2008) in eastern part European Alps. Spatial variability, diurnal cycles, temporal correlations,...
Gridded precipitation data sets are frequently used to evaluate climate models or remove model output biases. Although error prone due the high spatio-temporal variability of and considerable measurement errors, relatively few attempts have been made account for observational uncertainty in evaluation bias correction studies. In this study, we compare three types European daily featuring two Pan-European a set that combines eight very high-resolution station-based regional sets. Furthermore,...
Deep convection is a key process in the climate system and main source of precipitation tropics, subtropics, mid-latitudes during summer. Furthermore, it related to high impact weather causing floods, hail, tornadoes, landslides, other hazards. State-of-the-art models have parameterize deep due their coarse grid spacing. These parameterizations are major uncertainty long-standing model biases. We present North American scale convection-permitting simulation that able explicitly simulate its...
Novel high-resolution convection-permitting regional climate simulations over the US employing pseudo-global warming approach are used to investigate changes in convective population and thermodynamic environments a future climate. Two continuous 13-year were conducted using (1) ERA-Interim reanalysis (2) plus perturbation for RCP8.5 scenario. The adequately reproduce observed precipitation diurnal cycle, indicating that they capture organized propagating convection most models cannot...
Wind energy resource is subject to changes in climate. To investigate the impacts of climate change on future European wind power generation potential, we analyze a multi-model ensemble most recent EURO-CORDEX regional simulations at 12 km grid resolution. We developed mid-century plant scenario focus impact assessment relevant locations for industry. found that, under two greenhouse gas concentration scenarios, annual yield farms fleet as whole will remain within ±5% across 21st century. At...
Climate projections at very high resolution (kilometre-scale grid spacing) are becoming affordable. These ‘convection-permitting’ models (CPMs), commonly used for weather forecasting, better represent land-surface characteristics and small-scale processes in the atmosphere such as convection. They provide a step change our understanding of future changes local scales extreme events. For short-duration precipitation extremes, this includes capturing storm feedbacks, which may modify...
A large number of recent studies have aimed at understanding short-duration rainfall extremes, due to their impacts on flash floods, landslides and debris flows potential for these worsen with global warming. This has been led in a concerted international effort by the INTENSE Crosscutting Project GEWEX (Global Energy Water Exchanges) Hydroclimatology Panel. Here, we summarize main findings so far suggest future directions research, including: benefits convection-permitting climate...
Abstract A unique, high-resolution, hydroclimate reanalysis, 40-plus-year (October 1979–September 2021), 4 km (named as CONUS404), has been created using the Weather Research and Forecasting Model by dynamically downscaling of fifth-generation European Centre for Medium-Range Forecasts (ECMWF) atmospheric reanalysis global climate dataset (ERA5) over conterminous United States. The paper describes approach generating dataset, provides an initial evaluation, including biases, indicates how...
Abstract Changes in precipitation have far‐reaching consequences on human society and ecosystems as has been demonstrated by recent severe droughts California the Oklahoma region. Droughts are beside tropical cyclones most costly weather climate related extreme events U.S. We apply a type (WT) analysis to reanalysis data from 1979–2014 that characterize typical conditions over contiguous United States. This enables us assign trends within 1980–2010 changes WT frequencies intensities. show...
The occurrence of environmental conditions favorable for severe convective storms was assessed in an ensemble 14 regional climate models covering Europe and the Mediterranean with a horizontal grid spacing 0.44°. These included collocated presence latent instability strong deep-layer (surface to 500 hPa) wind shear, which is conducive well-organized storms. precipitation used as proxy initiation. Two scenarios (RCP4.5 RCP8.5) were investigated by comparing two future periods (2021–50...
A single hailstorm can cause losses in the billion-dollar range if it occurs over a densely populated area. Property from hailstorms are rising with time mainly due to combination of increases population density and wealth. Report based observational hail data alone highly inhomogeneous unable discriminate between climate societal changes. Here we present statistical approach that estimates hazard large-scale environmental conditions. Using daily ERA-Interim reanalysis large observations...
Abstract Summer and winter daily heavy precipitation events (events above the 97.5th percentile) are analyzed in regional climate simulations with 36-, 12-, 4-km horizontal grid spacing over headwaters of Colorado River. Multiscale evaluations useful to understand differences across scales evaluate effects upscaling finescale processes coarser-scale features associated precipitating systems. Only model is able correctly simulate totals summertime events. For events, results from 4- 12-km...
Mesoscale convective systems (MCSs) are complexes of thunderstorms that become organized and cover hundreds kilometres over several hours. MCSs prolific rain producers in the tropics mid-latitudes major cause warm-season flooding. Traditionally, climate models have difficulties simulating partly due to misrepresentation complex process interactions operate across a large range scales. Significant improvements been found kilometre-scale explicitly simulate deep convection. However, these grey...
Abstract Impacts modelers and stakeholders use publicly available data sets of downscaled climate projections to assess design infrastructure for changes in future rainfall extremes. If differences across exist, resilience decisions could change depending on which single set is used. We U.S. extremes from 2044–2099 compared with 1951–2005 based 227 under RCP4.5 RCP8.5 five widely used sets. show there are large the magnitude its spatial structure between At continental scale, different...
