The capability to represent current climate condition and projected scenarios at km-scale is a challenging task for the climate community. Italy, like other countries of the Mediterranean area, has been observing an increase in extreme weather events, causing huge impacts with consequences to assets and people. Therefore, enhancing the understanding of the local climate represents a pillar in the framework of the climate change adaptation process. In this perspective, CMCC tried to go beyond the current limitation in the convection permitting strategies (as time-slice approach), simulating more than 30-years at around 2 km grid spacing over the whole Italian peninsula. CMCC applies dynamical downscaling (relying on the COSMO-CLM numerical model) of the ERA5 to understand the current climate, and analyzes the climate scenarios at around 2 km, downscaling the CMCC-CM global model (adopting the IPCC RCP4.5 and 8.5).

This webinar is intended to:

• present the available datasets on the CMCC Data Delivery System;
• illustrate the main scientific results, exploiting the potential of convection-permitting models in terms of hourly precipitation patterns, orography effects, and urban climate dynamics;
• show the climate scenarios at km-scale in terms of extreme events and in comparison with state of the art (as data coherence, model performance and consistency).
