Flash drought response to precipitation and atmospheric evaporative demand in Sspain 2021 Access copy available to the general public Unrestricted Flash drought is the result of strong precipitation deficits and/or anomalous increases in atmospheric evaporative demand (AED), which triggers a rapid decline in soil moisture and stresses vegetation over short periods of time. However, little is known about the role of precipitation and AED in the development of flash droughts. For this paper, we compared the standardized precipitation index (SPI) based on precipitation, the evaporative demand drought index (EDDI) based on AED, and the standardized evaporation precipitation index (SPEI) based on the differences between precipitation and AED as flash drought indicators for mainland Spain and the Balearic Islands for 1961–2018. The results show large differences in the spatial and temporal patterns of flash droughts between indices. In general, there was a high degree of consistency between the flash drought patterns identified by the SPI and SPEI, with the exception of southern Spain in the summer. The EDDI showed notable spatial and temporal differences from the SPI in winter and summer, while it exhibited great coherence with the SPEI in summer. We also examined the sensitivity of the SPEI to AED in each month of the year to explain its contribution to the possible development of flash droughts. Our findings showed that precipitation is the main driver of flash droughts in Spain, although AED can play a key role in the development of these during periods of low precipitation, especially in the driest areas and in summer. info:eu-repo/grantAgreement/EC/FP7/323241/EU/Climate Knowledge for Europe - Coordination and Support Action/JPI CLIMATE CSA info:eu-repo/grantAgreement/EC/H2020/690462/EU/European Research Area for Climate Services/ERA4CS This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 690462-ERA4CS info:eu-repo/grantAgreement/ES/MICINN/PID2019-108589RA-I00 info:eu-repo/grantAgreement/ES/MINECO-FEDER/CGL2017-82216-R info:eu-repo/grantAgreement/ES/MINECO-FEDER/PCI2019-103631 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.11 2021 METEOROLOGY & ATMOSPHERIC SCIENCES 59 / 94 = 0.628 2021 Q3 T2 ENVIRONMENTAL SCIENCES 169 / 279 = 0.606 2021 Q3 T2 0.692 2021 Environmental Science (miscellaneous) 2021 Q2 Atmospheric Science 2021 Q2 3.7 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Domínguez-Castro, F.
