Spatio-Temporal Analysis of Droughts in Semi-Arid Regions by Using Meteorological Drought Indices
Six meteorological drought indices including percent of normal (PN), standardized precipitation index (SPI), China-Z index (CZI), modified CZI (MCZI), Z-Score (Z), the aridity index of E. de Martonne (I) are compared and evaluated for assessing spatio-temporal dynamics of droughts in six climatic regions in Iran. Results indicated that by consideration of the advantages and disadvantages of the mentioned drought predictors in Iran, the Z-Score, CZI and MCZI could be used as a gooddoi:10.3390/atmos4020094 fatcat:cwksiocdvvgvvmotzie4ikxtd4
