Abstract The Mediterranean is expected to be one of the most prominent and vulnerable climate change “hotspots” twenty-first century, physical mechanisms underlying this finding are still not clear. Furthermore, complex interactions feedbacks involving ocean–atmosphere–land–biogeochemical processes play a role in modulating environment region on range spatial temporal scales. Therefore, it critical provide robust information for use vulnerability–impact–adaptation assessment studies...
VALUE is an open European collaboration to intercompare downscaling approaches for climate change research, focusing on different validation aspects (marginal, temporal, extremes, spatial, process‐based, etc.). Here we describe the participating methods and first results from experiment, using “perfect” reanalysis (and reanalysis‐driven regional model (RCM)) predictors assess intrinsic performance of precipitation temperatures over a set 86 stations representative main climatic regions in...
Credible information about the properties and changes of extreme events on regional local scales is prime importance in context future climate change. Within EU‐COST Action VALUE a comprehensive validation framework for downscaling methods has been developed. Here we present results extremes temperature precipitation from perfect predictor experiment that uses reanalysis‐based predictors to isolate skill. The raw reanalysis output reveals there mostly large bias with respect index values at...
Temporal variability is an important feature of climate, comprising systematic variations such as the annual cycle, well residual temporal short‐term variations, spells and from interannual to long‐term trends. The EU‐COST Action VALUE developed a comprehensive framework evaluate downscaling methods. Here we present evaluation perfect predictor experiment for variability. Overall, behaviour different approaches turned out be expected their structure implementation. chosen regional climate...
Expected climate change estimations for the Carpathian basin and especially, Hungary, are summarized 2071-2100 period on basis of results from project PRUDENCE.Different regional models (RCMs) used 50 km as horizontal spatial resolution, evaluated A2 B2 global emission scenarios.Results suggest that in case temperature, a warming trend is evident basin.The largest expected summer.The annual total precipitation not significant.However, significantly large opposite trends different...
Abstract This paper presents a validation study for high-resolution version of the Regional Climate Model 3 (RegCM3) over Carpathian basin and its surroundings. The horizontal grid spacing model is 10 km—the highest reached by RegCM3. ability to capture temporal spatial variability temperature precipitation region interest evaluated using metrics spanning wide range (daily climatology) (inner domain average local) scales against different observational datasets. simulated period 1961–90....
ABSTRACT The estimated future changes of precipitation and precipitation‐related climate indices for the Carpathian Region are analysed in this paper. Eleven regional model ( RCM ) simulations from ENSEMBLES project taking into account intermediate A1B emission scenario used, hence, analysis also includes uncertainty assessments. Validation results showed that target area overestimate throughout year, except summer, when underestimation occurs. In order to eliminate these systematic errors...
In the last decade, Regional Climate Models (RCMs) nested in Global (GCMs) have become essential tools to make climate projections with fine spatial resolution. this paper, control runs of RCMs RegCM and PRECIS are discussed compared for Central/Eastern European region. Both three-dimensional, sigma-coordinate, primitive equation models, experiments (1961-1990), they use initial lateral boundary conditions from Centre Medium-range Weather Forecast (ECMWF) reanalysis data sets (ERA-40). For...
Studies on climate change impacts are essential for identifying vulnerabilities and developing adaptation options. However, such studies depend crucially the availability of reliable data. In this study, we introduce climatological database called FORESEE (Open Database Climate Change Related Impact Studi es in C e ntral E urope), which was developed to support research Central Eastern Europe: region where knowledge possible effects is inadequate. A questionnaire‐based survey used specify...
Abstract. Four regional climate models (RCMs) were adapted in Hungary for the dynamical downscaling of global projections over Carpathian Basin: (i) ALADIN-Climate model developed by Météo France on basis ALADIN short-range modelling system; (ii) PRECIS available from UK Met Office Hadley Centre; (iii) RegCM originally at US National Center Atmospheric Research, is maintained International Centre Theoretical Physics Trieste; and (iv) REMO Max Planck Institute Meteorology Hamburg. The RCMs...
In order to support political and economical decision makers by providing climate information for the future, it is essential analyze regional model results. These models are capable describe conditions of individual countries using 25 km horizontal resolution, whereas global too coarse such details. This paper discusses effects warming experiments from PRECIS developed at Hadley Centre UK Met Office. Since was adapted Department Meteorology, Eötvös Loránd University in recent years,...
