A high-resolution view of the recent drought trends over the Iberian Peninsula

Droughts are a long-term weather-driven extreme event which occurs worldwide with great socio-economic impacts, namely in the Mediterranean and Iberian regions. In changing climate rising temperatures, events, such as droughts, expected to increase frequency intensity, particularly climates. this context, assessment of evolution drought terms its duration intensity Peninsula (IP) is paramount, it affects several activities. The use new high-resolution gridded datasets allows for identification patterns finer temporal spatial scales. current study, IP was accomplished both Standardized Precipitation Evaporation Index (SPEI) (SPI) short-, medium- long-timescales. A recently developed dataset, Iberia01, used, period 1971–2015, 0.1° horizontal resolution. lower-resolution CRU dataset also used. clear drying trend most identified indices datasets. trends positive territory, whereas mean decreases slightly. drivers decreased precipitation increased reference evapotranspiration. Iberia01 allowed identify more complex trends, mainly due improved representation precipitation.
