IMERG-Based Meteorological Drought Analysis over Italy

The Mediterranean region is an area particularly susceptible to water scarcity and drought. In this work, drought has been analyzed in Italy using multiple timescales of the standardized precipitation index (SPI) evaluated from Integrated Multi-satellitE Retrievals for Global Precipitation Measurement product 2000 2020. particular, characteristics (severity, duration, intensity) have estimated by means run theory applied SPI values calculated 3325 grid points falling within Italian territory. Results clearly indicate that although a high number events identified short timescale, these present lower duration lesser severity than long-timescale droughts. main outcomes study, with indication spatial distribution Italy, allow identifying areas could also face stress conditions future, thus requiring monitoring adequate adaptation strategies.
