CLIMED: a website concerning climate change impacts over Italian Energetic System

Il sito CLIMED presenta dati degli output dei modelli climatici regionali del progetto Euro-CORDEX e degli archivi di dati osservati E-OBS e MESAN. Le variabili esaminate sono: valore medio, minimo e massimo della temperatura superficiale dell’aria, precipitazione totale, intensità del vento. Per caratterizzare gli eventi estremi sono presentati cinque indici ETCCDI più uno che descrive i fenomeni di neve bagnata.

The intensification of extreme weather events represents a serious risk for human activities and infrastructures. The analysis of the results produced by the state of art of climate models let to get new knowledge about climate variability and change over the coming decades. The CLIMED website aims to present and disseminate some information gathered by elaborating the outputs of the regional climate models delivered in the Euro-CORDEX European Project. CLIMED report the current climate using E-OBS, MESAN archives as reference for observed data. The presented data are elaborated at different time scales (annual and seasonal) over a period from 1971 to 2100 by considering the RCPs 4.5 greenhouse-gas forcings schema.

The variables considered are those which are likely to have serious impacts on the electrical system. To investigate the mean climate changes six variables have been chosen: mean, maximum and minimum surface air temperature, total precipitation, wind intensity. To study the change of extreme events five ETCCDI indexes plus one describing wet-snow phenomena are available: summer days (SU), tropical nights (TR), consecutive dry days (CDD), extreme precipitations (R99PTOT), frost days (FD), wet-snow frequency (WSF). The analysis domain considers the whole Italy with a spatial resolution depending on the models.Time series data are presented with spatial detail of the twenty Italian regions.

The website is accessible at http://climed.rse-web.it.
