Therefore, it is necessary to evaluate whether these indices are applicable for a given region. This study evaluated the ability of the self-calibrating Palmer Drought Severity Index(sc PDSI), the Standardized Precipitation Evapotranspiration Index(SPEI), and the Standardized Moisture Anomaly Index(SZI) to describe the dry...
