CECILIA Regional Climate Simulations for Future Climate: Analysis of Climate Change Signal

Regional climate models (RCMs) are important tools used for downscaling climate simulations from global scale models. In project CECILIA, two RCMs were used to provide climate change information for regions of Central and Eastern Europe. Models RegCM and ALADIN-Climate were employed in downscaling global simulations from ECHAM5 and ARPEGE-CLIMAT under IPCC A1B emission scenario in periods 2021–2050 and 2071–2100. Climate change signal present in these simulations is consistent with respective driving data, showing similar large-scale features: warming between 0 and 3°C in the first period and 2 and 5°C in the second period with the least warming in northwestern part of the domain increasing in the southeastern direction and small precipitation changes within range of

Projected changes in winter climate in Beskids Mountains during 21st century

. Farda A., Štěpánek P., Zahradníček P., Skalák P, Meitner J. 2017: Projected changes in winter climate in Beskids Mountains during 21st century. – Beskydy, 10 (1, 2): 123–134 We have investigated the future changes of climate conditions during the winter season in the Beskids Mountains. During the 21st century mean winter temperature will increase by 2.0–6.3 °C and winter precipitation will increase by 12.5 – to 17.5 % depending on the scenario. Higher winter temperatures will be reflected in the reduced number of frost days, the number of which may drop by 40 % according to the RCP8.5 scenario. Whilst our study expects general increase in precipitation, higher temperatures will lead to an increased evapotranspiration and also change in the form of precipitation from solid (snow, rime) to liquid (rain, drizzling). Such trends could further propel the unfavorable changes in the water balance budget.
