Recent trends and ENSO influence on droughts in northern Chile: an application of the Standardized Precipitation Evapotranspiration Index

The study identifies increasing dryness in the Coquimbo region of Chile, particularly during spring and summer, noting that the frequency and duration of extreme dry events have increased over recent decades.

• Analysis of stations in the Coquimbo region indicates that spring and summer seasons exhibit negative trends, signifying increasing dryness, with significant SPEI value trends around -0.05 yr-1.
• There has been an increase in the occurrence of dry conditions across various magnitudes over the last few decades, alongside a slight increase in the duration of extreme climatic events.
