abstract = {We perform simulations with the WRF regional climate model
at 12 and 3 km grid resolution for the current and future
climates over Central Europe and evaluate their added value
with a focus on the daily cycle and frequency distribution
of rainfall and the relation between extreme precipitation
and air temperature. First, a 9 year period of ERA-Interim
driven simulations is evaluated against observations; then
global climate model runs (MPI-ESM-LR RCP4.5 scenario) are
downscaled and analyzed for three 12-year periods: a
control, a mid-of-century and an end-of-century projection.
The higher resolution simulations reproduce both the diurnal
cycle and the hourly intensity distribution of precipitation
more realistically compared to the 12 km simulation.
Moreover, the observed increase of the temperature–extreme
precipitation scaling from the Clausius–Clapeyron (C–C)
scaling rate of $~ 7\%$ K−1 to a super-adiabatic scaling
rate for temperatures above 11 °C is reproduced only by the
3 km simulation. The drop of the scaling rates at high
temperatures under moisture limited conditions differs
between sub-regions. For both future scenario time spans
both simulations suggest a slight decrease in mean summer
precipitation and an increase in hourly heavy and extreme
precipitation. This increase is stronger in the 3 km runs.
Temperature–extreme precipitation scaling curves in the
future climate are projected to shift along the $7\%$ K−1
trajectory to higher peak extreme precipitation values at
higher temperatures. The curves keep their typical shape of
C–C scaling followed by super-adiabatic scaling and a
drop-off at higher temperatures due to moisture limitation.},
