abstract = {In the framework of the EURO-CORDEX initiative an ensemble
of European-wide high-resolution regional climate
simulations on a 0.11∘(∼12.5km) grid has been generated.
This study investigates whether the fine-gridded regional
climate models are found to add value to the simulated mean
and extreme daily and sub-daily precipitation compared to
their coarser-gridded 0.44∘(∼50km) counterparts.
Therefore, pairs of fine- and coarse-gridded simulations of
eight reanalysis-driven models are compared to fine-gridded
observations in the Alps, Germany, Sweden, Norway, France,
the Carpathians, and Spain. A clear result is that the
0.11∘ simulations are found to better reproduce mean and
extreme precipitation for almost all regions and seasons,
even on the scale of the coarser-gridded simulations (50
km). This is primarily caused by the improved representation
of orography in the 0.11∘ simulations and therefore
largest improvements can be found in regions with
substantial orographic features. Improvements in reproducing
precipitation in the summer season appear also due to the
fact that in the fine-gridded simulations the larger scales
of convection are captured by the resolved-scale dynamics .
The 0.11∘ simulations reduce biases in large areas of the
investigated regions, have an improved representation of
spatial precipitation patterns, and precipitation
distributions are improved for daily and in particular for 3
hourly precipitation sums in Switzerland. When the
evaluation is conducted on the fine (12.5 km) grid, the
added value of the 0.11∘ models becomes even more
obvious.},
