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...
Abstract This study analyses long‐term changes in drought indices (Standardised Precipitation Index—SPI, Standardised Precipitation–Evapotranspiration Index—SPEI) at 1 and 3 months scales 182 stations 11 central eastern European countries during 1949–2018. For comparative purposes, the necessary atmospheric evaporative demand (AED) to obtain SPEI was calculated using two methods, Hargreaves‐Samani (SPEIH) Penman‐Monteith (SPEIP). The results show some relevant tendencies indices....
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...
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...
Abstract The current study focuses on the RegCM4.5 model and specifically a comparison of hydrostatic non‐hydrostatic approaches as well different microphysical parameterisations planetary boundary layer (PBL) schemes. main goal paper is to simulate historical regional precipitation characteristics Carpathian region reliably possible. For this purpose, seven experiments at 10 km horizontal resolution were completed for 10‐year period (1981–1990) using ERA‐Interim reanalysis data (with 0.75°...
The goal of the present paper is to investigate whether any objectively defined and statistically significant changes can be discovered in one longest homogenized instrumental temperature records East-Central Europe. Thus, it hoped that analysis will add earlier attempts elucidate persistence warming period observed early 20th century. Similar global tendency, Early Twentieth Century Warming (hereinafter, ETCW) identified between 1931 1951 annual mean time series Keszthely, a small town...
The Western Cape province is among the best wine-producing regions; however, has been facing environmental challenges due to rapidly changing climate. This study analyses projected changes in temperature and precipitation patterns across seven districts using high-resolution regional climate model (RCM) simulations from CORDEX-Africa framework. highlight spatial variability variable topography microclimates within wherein conditions are over selected regions. Olifants River experience most...
As global warming intensifies, the building of adaptation and mitigation strategies has become an urgent task. In centre these often lie extreme weather events, which are expected to even more severe frequent in next decades. Therefore, extending our knowledge on potential changes events is crucial provide assistance for appropriate preparation planning necessary actions. Using latest CMIP6 climate model simulations available IPCC’s Interactive Atlas (IA), a study focusing Europe...
Understanding sub-daily scale temperature variability can be used for evaluating the impacts of climate change on human health, agriculture and daily life. In particular, higher fluctuations (within a day, or from one day to another) increase physiological psychological stress, demanding more frequent adaptation in areas such as clothing choices energy management. The Pannonian Basin, encompassing Hungary, provides an ideal setting this analysis due its distinctive climate, well-defined four...
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...
In order to estimate the future regional climate change for Carpathian Basin located in Central/Eastern Europe, outputs from several RCMs (from completed European project ENSEMBLES) are summarized and analyzed using SRES A1B scenario.Composite maps of projected annual seasonal temperature precipitation changes generated RCM simulations (with 25 km spatial resolution) reference period 1961-1990, target periods 2021-2050, 2071-2100.Overall, results suggest significant warming Hungary.Projected...
