- Abstract
- Forecasting severe storms and floods is one of the main challenges of 21th century. Floods are the most dangerous
meteorological hazard in the Mediterranean basins due to both the number of people affected and to the relatively
high frequency by which human activities and goods suffer damages and losses. The numerical simulations of
extreme events which happen over small basins as the Mediterranean ones are need a very fine-resolution in space
and time and as a consequence considerable memory and computational power are required. Since the resources
provided by the PRACE project represent the solution for satisfying such requirements, the Super Computing of
Extreme Natural Events (SCENE) project has been proposed.
SCENE aims to provide an advanced understanding of the intrinsic predictability of severe precipitation processes
and the associated predictive ability of high-resolution meteorological models with a special focus on flash
flood-producing storms in regions of complex orography (e.g. Mediterranean area) through the assessment of the
role of both the convective and microphysical processes. The meteorological model considered in the project is
the Weather Research and Forecasting (WRF) model, a state of the art mesoscale numerical weather prediction
system designed to serve both operational forecasting and atmospheric research needs. Thus, among all the
parameterizations available in the WRF model, the WRF Single-Moment 6-Class Scheme and the Thompson
microphysics scheme will be adopted for the numerical simulations in combination with three different approaches
for the treatment of the convective processes, that is the use of explicit method, Betts-Miller-Janjic Scheme and
Kain-Fritsch.
As for flash-flood producing storms, the project considers the recent sequence of extreme events occurred in
the north-western portion of the Mediterranean sea; some of these events are the so-called critical cases of the
DRIHM project (www.drihm.eu), i.e. selected severe weather events considered for the high-end simulations and
the completion of the flood forecasting chain.
A further aim of the SCENE project is a performance analysis of the WRF model. We will arrange a set of test to
study the scalability of the model, the impact of nesting domains, to evaluate I/O operation issues, and to compare
performance using shared and distributed memory architectures when it is possible. The aim is to obtain these
information by varying physical parameterizations to classify HPC resources on the base of such benchmarking
information.
The SCENE project has been founded and it is now starting. (literal)
