| Abstract | In this study we provide a global assessment of the performance of different drought indices for monitoring drought impacts to streamflows, soil moisture, forest growth and crop yields. For this purpose, we compare the Standardized Precipitation Index (SPI), four versions of the Palmer Drought Severity Index (PDSI) and the Standardized Precipitation Evapotranspiration Index (SPEI). We have found a higher capability of the SPEI and the SPI drought indices, which are calculated on different time-scales, than the Palmer indices to explain the drought impacts. We have found small differences in the performance of the SPI and the SPEI indices, but the SPEI has been the drought index that records the best correlations between drought and the response variables in summer, the season in which more drought-related impacts are recorded and in which drought monitoring is critical. |
