Description:
Abstract Exploiting the added value of the ensemble of
high-resolution model simulations provided by the Med-
CORDEX coordinated initiative, an updated assessment of
Mediterranean extreme precipitation events as represented
in different observational, reanalysis and modelling datasets
is presented. A spatiotemporal characterisation of the
long-term statistics of extreme precipitation is performed,
using a number of different diagnostic indices. Employing
a novel approach based on the timing of extreme precipitation events a number of physically consistent subregions
are defined. The comparison of different diagnostics
over the Mediterranean domain and physically homogeneous
sub-domains is presented and discussed, focussing
on the relative impact of several model configuration features
(resolution, coupling, physical parameterisations)
on the performance in reproducing extreme precipitation
events. It is found that the agreement between the observed
and modelled long-term statistics of extreme precipitation
is more sensitive to the model physics, in particular convective
parameterisation, than to other model configurations
such as resolution and coupling.
