Abstract
The third and fourth statistical moments, that is, skewness and
kurtosis, are compared for daily maximum temperature in summer
and daily minimum temperature in winter between observations,
outputs of two global climate models, four versions of
statistical downscaling, and weather generator. The comparison is
performed at six stations in central Europe. None of the
simulation models can be considered as superior to the others.
Causes of a good correspondence with and differences from
observations are identified e.g. in the treatment of physics in
the models, imperfections in physical parameterizations, or a
linear transfer of properties from predictors onto predictands in
statistical downscaling.
