abstract = "The aim of this work is to present preliminary results of the
statistical and dynamical simulations carried out within the
framework of the Flagship Pilot Study in southeastern South
America (FPS-SESA) endorsed by the Coordinated Regional Climate
Downscaling Experiments (CORDEX) program. The FPS-SESA initiative
seeks to promote inter-institutional collaboration and further
networking with focus on extreme rainfall events. The main
scientific aim is to study multi-scale processes and interactions
most conducive to extreme precipitation events through both
statistical and dynamical downscaling techniques, including
convection-permitting simulations. To this end, a targeted
experiment was designed considering the season October 2009 to
March 2010, a period with a record number of extreme precipitation
events within SESA. Also, three individual extreme events within
that season were chosen as case studies for analyzing specific
regional processes and sensitivity to resolutions. Four dynamical
and four statistical downscaling models (RCM and ESD respectively)
from different institutions contributed to the experiment. In this
work, an analysis of the capability of the set of the FPS-SESA
downscaling methods in simulating daily precipitation during the
selected warm season is presented together with an integrated
assessment of multiple sources of observations and available
CORDEX Regional Climate Model simulations. Comparisons among all
simulations reveal that there is no single model that performs
best in all aspects evaluated. The ability in reproducing the
different features of daily precipitation depends on the model.
However, the evaluation of the sequence of precipitation events,
their intensity and timing suggests that FPS-SESA simulations
based on both RCM and ESD yield promising results. Most models
capture the extreme events selected, although with a considerable
spread in accumulated values and the location of heavy
precipitation.",
