Participation to 101st AMS (American Meteorological Society) Annual Meeting in the framework of the LEXIS Project

A poster about WRF-ERDS workflow has been presented by Paola Mazzoglio to 101st AMS (American Meteorological Society), the world’s largest yearly gathering for the weather, water, and climate community.

In the framework of the Weather and Climate Large-scale Pilot in the LEXIS project, CIMA Research Foundation is running a 7.5 km resolution WRF (Weather Research and Forecasting) model with European coverage, radar assimilation over the Italian area, and daily updates with 48 hours forecast. WRF data is processed by ITHACA ERDS (Extreme Rainfall Detection System), an early warning system for the monitoring and forecasting of heavy rainfall events. The entire WRF - ERDS workflow has been applied to two of the most severe heavy rainfall events that affected Italy during 2020.

The obtained results highlight how improved rainfall forecast, made available thanks to the use of HPC resources, significantly increases the capabilities of an operational early warning system in the extreme rainfall detection. Global-scale low-resolution rainfall forecasts like GFS are in fact widely known as good sources of information for the identification of large-scale precipitation patterns but lack precision for local-scale application.
