he main goal of this work is to provide a support for heat waves risk for the city of Prato through the hazard evaluation considering humidex index. The climate analysis has been carried out using a multi-model ensemble of EURO- CORDEX data at high resolution (about 12 km). The approach we propose consists in defining a multicriteria analysis for searching the most appropriate models subset. It is based on the assumption of giving a greater weight to the models with better performance in representing the trends of the variables of interest. After applying the selection criterion, a bias correction method has been used to reduce selected models bias. The analyses have been conducted using the tools available in CLIME service, a horizontal climate service currently developed at CMCC for providing climate data useful for a wide range of users and stakeholders.

Abstract
he main goal of this work is to provide a support for heat waves risk for the city of Prato through the hazard evaluation considering humidex index. The climate analysis has been carried out using a multi-model ensemble of EURO- CORDEX data at high resolution (about 12 km). The approach we propose consists in defining a multicriteria analysis for searching the most appropriate models subset. It is based on the assumption of giving a greater weight to the models with better performance in representing the trends of the variables of interest. After applying the selection criterion, a bias correction method has been used to reduce selected models bias. The analyses have been conducted using the tools available in CLIME service, a horizontal climate service currently developed at CMCC for providing climate data useful for a wide range of users and stakeholders.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
