Climate Change Projections of Dry and Wet Events in Iberia Based on the WASP-Index
نویسندگان
چکیده
The Weighted Anomaly of Standardized Precipitation Index (WASP-Index) was computed over Iberia for three monthly timescales (3-month, 6-month and 12-month) in 1961–2020, based on an observational gridded precipitation dataset (E-OBS), between 2021 2070, bias-corrected generated by a six-member climate model ensemble from EURO-CORDEX, under two Representative Concentration Pathways (RCPs), RCP4.5 RCP8.5. area-mean values revealed upward trend the frequency occurrence intermediate-to-severe dry events Iberia, which will be strengthened future, particularly 12-month WASP (12m-WASP) intermediate Besides, number 3-month (3m-WASP) wet is projected to increase (mostly severest RCP4.5) but no evidence found more persistent 12m-WASP both RCPs. Despite important spatial heterogeneities, increase/decrease intensity, duration dry/wet scenarios, mainly southernmost regions (mainly Comunidad Valenciana, Región de Murcia, Andalucía Spain, Alentejo, Algarve Portugal), thus becoming exposed prolonged severe droughts future. This finding corroborates results previous studies.

Climate change, with effects on temperature and rainfall, has a great influence on dry period. Therefore, it is very important to study this phenomenon in the analysis of dry period length. In this study, we used GFDL-ESM2M and four RCP scenarios to simulate precipitation, maximum and minimum temperature and used CCT with statistical methods to downscale the results. The data used in this study...
