High Resolution Future Projections of Drought Characteristics in Greece Based on SPI and SPEI Indices

Future changes in drought characteristics Greece were investigated using dynamically downscaled high-resolution simulations of 5 km. The Weather Research and Forecasting model driven by EC-EARTH output for historical future periods, under Representative Concentration Pathways 4.5 8.5. For the analysis, standardized precipitation index (SPI) precipitation-evapotranspiration (SPEI) calculated. This work contributed to achieve an improved characterization expected Greece. Overall, results indicate that will face severe conditions upcoming years, particularly RCP8.5, up 8/5 y severity change signal. 6-month timescale indices suggest more prolonged events are with increase 4 months/5 y, areas central eastern part country near future, western parts far future. obtained a 12-month period 2075–2099 RCP8.5 have shown mean duration along entire country. Drought be lowland agricultural interest (e.g., Thessaly Crete).
