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...
The aim of the research project “Innovative Strategies for Observations in Arctic Atmospheric Boundary Layer (ISOBAR)” is to substantially increase understanding stable atmospheric boundary layer (SBL) through a combination well-established and innovative observation methods as well by models different complexity. During three weeks February 2017, first field campaign was carried out over sea ice Bothnian Bay vicinity Finnish island Hailuoto. were based on ground-based eddy-covariance (EC),...
Abstract The Innovative Strategies for Observations in the Arctic Atmospheric Boundary Layer Program (ISOBAR) is a research project investigating stable atmospheric boundary layer (SBL) processes, whose representation still poses significant challenges state-of-the-art numerical weather prediction (NWP) models. In ISOBAR ground-based flux and profile observations are combined with remote sensing methods extensive usage of different unmanned aircraft systems (UAS). During February 2017 2018...
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...
Abstract Heatwaves (HWs) are high-impact phenomena stressing both societies and ecosystems. Their intensity frequency expected to increase in a warmer climate over many regions of the world. While these impacts can be wide-ranging, they potentially influenced by local regional features such as topography, land cover, urbanization. Here, we leverage recent advances very high-resolution modelling required elucidate heatwaves at fine scales. Further, aim understand how new generation km-scale...
Abstract. The Coordinated Regional Climate Downscaling Experiment (CORDEX) is a scientific effort of the World Research Program (WRCP) for coordination regional climate initiatives. In order to accept an experiment, CORDEX provides experiment guidelines, specifications domains, and data access archiving. experiments are important study at scale, same time, they also have very prominent role in providing high quality. Data requirements intended cover all possible needs stakeholders scientists...
Abstract In a recent study, Coppola et al. assessed the ability of an ensemble convection‐permitting models (CPM) to simulate deep convection using three case studies. The exhibited strong discrepancies between models, which were attributed various factors. order shed some light on issue, we quantify in this article uncertainty associated different physical parameterizations from that initial conditions, often referred as internal variability. For purpose, establish framework both signals...
Abstract Recent studies using convection-permitting (CP) climate simulations have demonstrated a step-change in the representation of heavy rainfall and characteristics (frequency-intensity) compared to coarser resolution Global Regional models. The goal this study is better understand what explains weaker frequency precipitation CP ensemble by assessing triggering process different ensembles regional available over Europe. We focus on statistical relationship between tropospheric...

Abstract A realistic representation of the stable atmospheric boundary layer in numerical weather prediction (NWP) and climate models is still a challenge. We study evolution over snow‐covered sea ice Bothnian Bay during wintertime 2018. perform high‐resolution model experiments with Weather Research Forecasting its single‐column configuration default mesoscale to assess which physical processes are essential predict near‐surface variables correctly. evaluate our runs against unique...
&lt;p&gt;We present a multi-model ensemble of regional climate model scenario simulations run at scales allowing for explicit treatment convective processes (2-3km) over historical and end century time slices, providing an overview future precipitation changes the Alpine domain within convection-permitting CORDEX-FPS initiative.

Abstract We present the first evaluation of wind field from CORDEX-FPS ensemble kilometer-scale simulations, with focus on Adriatic region. Kilometer-scale climate models, also known as convection-permitting models (CPMs), produce a good representation small-scale topographic features and consequently more detailed depiction dynamical thermal circulation. These enable reliable view characteristics field, especially in coastal regions over complex terrain, such Adriatic. investigate...
Most heavy precipitation events occurring in the world are associated with convective processes. As these phenomena produce severe economic and societal impacts, it is crucial to get know their behaviour evolution a future climate. For this reason, international project CORDEX (Coordinated Regional climate Downscaling Experiment) proposed Flagship Pilot Study on Convective at high resolution over Europe Mediterranean, focused study of convection Europe. In initiative, multi-model...
