waves and cold spells over Central Europe. We compare EURO-CORDEX RCMs driven by both global climate
models and the ERA-INTERIM reanalysis against observations over the reference period 1980–2005. We focus
on heat waves in summer and cold spells in winter over Central Europe (48.5–51.5 N and 12–18 E).
We find that some RCMs have difficulties to reproduce basic characteristics of heat waves and cold spells (such as
frequency and duration). Most RCMs overestimate length of the longest heat waves and cold spells. We detected
that models have a stronger tendency to cluster days of heat waves and cold spells in individual years compared
to observations, which results in more extreme seasons in RCMs. We analyze climatological characteristics
and meteorological factors related to the persistence of heat waves and cold spells, with focus on simulated
atmospheric circulation and precipitation deficits.Workplace Institute of Atmospheric Physics Contact Kateřina Adamovičová, adamovicova@ufa.cas.cz, Tel.: 272 016 012 ; Kateřina Potužníková, kaca@ufa.cas.cz, Tel.: 272 016 019 Year of Publishing 2018
