Heavy precipitation affected Central Europe in May/June 2013, triggering damaging floods both on the Danube and Elbe rivers. Based a modelling approach with COSMO-CLM, moisture fluxes, backward trajectories, cyclone tracks fields are evaluated for relevant time period 30 May–2 June 2013. We identify potential sources quantify their contribution to flood event focusing basin through sensitivity experiments: Control simulations performed undisturbed ERA-Interim boundary conditions, while...
This study aims to assess the skill of regional climate models (RCMs) at reproducing climatology Mediterranean cyclones. Seven RCMs are considered, five which were also coupled with an oceanic model. All simulations forced lateral boundaries by ERA-Interim reanalysis for a common 20-year period (1989–2008). Six different cyclone tracking methods have been applied all twelve RCM and in order from perspective definitions. reproduce main areas high occurrence region south Alps, Adriatic, Ionian...
Anthropogenic emissions are changing Earth’s global mean temperature towards levels unseen over the observational period. During Last Interglacial (LIG) warm period, 129-116 thousand years ago, reached up to 1-2 degrees above preindustrial conditions, forced primarily by changes in orbit. Both Greenland and Antarctic Ice sheet were smaller, with sea level at least 5m, potentially 10m, present levels. The seasonal distribution of solar insolation during LIG was characterized higher...
A twentieth century-long coupled atmosphere-ocean regional climate simulation with COSMO-CLM (Consortium for Small-Scale Modeling, Climate Limited-area Model) and NEMO (Nucleus European Modelling of the Ocean) is studied here to evaluate added value marginal seas over continental regions. The interactive coupling seas, namely Mediterranean, North Baltic Seas, atmosphere in region gives a comprehensive modelling system. It expected be able describe climatological features this geographically...
Abstract On Pentecost Monday, 9 June 2014, a severe linearly organized mesoscale convective system (MCS) hit Belgium and western Germany. This storm was one of the most thunderstorms in Germany decades. The synoptic-scale characteristics this are analyzed based on remote sensing data situ measurements. Moreover, forecast potential is evaluated using sensitivity experiments with regional climate model. key ingredients for development were concurrent presence low-level moisture, atmospheric...
Abstract. Enduring and extensive heavy precipitation events associated with widespread river floods are among the main natural hazards affecting central Europe. Since such characterized by long return periods, it is difficult to adequately quantify their frequency intensity solely based on available observations of precipitation. Furthermore, long-term rare, not homogeneous in space time, thus suitable running hydrological models (HMs) respect extremes. To overcome this issue, we make use...
Abstract. The frequency of extreme events has changed, having a direct impact on human lives. Regional climate models help us to predict these regional changes. This work presents an atmosphere–ocean coupled system model (RCSM; with the atmospheric component COSMO-CLM and ocean NEMO) over European domain, including three marginal seas: Mediterranean, North, Baltic Sea. To test model, we evaluate simulation more than 100 years (1900–2009) spatial grid resolution about 25 km. was nested into...
Abstract The total meridional heat transport (MHT) is relatively stable across different climates. Nevertheless, the strength of individual processes contributing to are not stable. Here we investigate MHT and its main components especially in atmosphere, five coupled climate model simulations from Deep‐Time Model Intercomparison Project (DeepMIP). These target early Eocene climatic optimum, a geological time period with high CO 2 concentrations, analog upper range end‐of‐century...

This work presents an atmosphere-ocean coupled system model (RCSM, with the atmospheric component COSMO-CLM and ocean NEMO) over European domain, including three marginal seas: Mediterranean, North Baltic Seas. To test model, we evaluate simulation more than one hundred years (1900–2009) spatial grid resolution about 25 km. was...
Paleoclimate models help us understand the complex influence of high CO2 concentration and other boundary conditions on large scale atmospheric circulation patterns. Based meridional heat transport analysis we investigate different phenomena, such as Hadley cell, monsoon extratropical cyclones, in simulations from Deep-Time Model Intercomparison Project (DeepMIP). For compare preindustrial early Eocene at a range levels (1x, 3x 6x values), which are targeting climate Early Climatic Optimum...

Abstract. Heavy precipitation leading to widespread river floods are one of the main natural hazards affecting Central Europe. Since extreme events associated with devastating have long return periods, long-term datasets needed adequately quantify frequency and intensity these events. As observations across Europe rare not homogeneous in space nor time, they generally suitable run hydrological models. In present study, a combined approach is presented on how generate consistent dataset based...
