(a–d) Trends of CIR and climatic variables in Iran, 2000–2023. (a) CIR trend, (b) AMT trend, (c) AP trend, (d) SPEI trend. The time series graph of the Standardized Precipitation Evapotranspiration Index (SPEI) from 2000 to 2023 demonstrates how climatic trends have influenced both drought and wet periods (d). This graph is presented without logarithmic transformation to preserve the actual temporal pattern of the drought index, allowing for a clearer understanding of the fluctuations in drought conditions over time.
