The study evaluates ability of current regional climate models (RCMs) to simulate basic spatial and temporal characteristics
of heat waves and cold spells over Central Europe. The focus is on regional heat waves/cold spells that
affect a larger area of Central Europe (approximately 47–53 N and 7–22 E). We examine how RCM simulations
driven by reanalysis reproduce such characteristics as frequency, temperature amplitude, length, cumulative temperature
excess, and spatial extent of heat waves/cold spells. We also analyze how recent major heat waves (1994,
2006, 2015) and cold spells (1996/97, 2011/12) in Central Europe are reproduced in the RCMs, and search for links
of models’ performance and biases to simulated atmospheric circulation, soil moisture/precipitation (for summer
heat waves), and snow cover (for winter cold spells).
