Short summary

Drought is an important climatic risk. This study analyses drought representation and propagation by regional climate models from Med-CORDEX simulations using standardized indices. Results show that these models improve meteorological drought representation, but uncertainties are identified in its propagation and the way soil moisture and hydrological droughts are characterized. These are mainly due to model structure, making further improvements in land surface modelling necessary.
