英文摘要	Although drought is a normal feature of climate, there is confusion about its characteristics in both arid and semi-arid regions. This study investigated the effects of changes in precipitation and temperature on spatio-temporal drought and humidity variations throughout the diverse (principally aridand semi-arid) climates of Iran during recent decades using the Pedj Drought Index (PDI). The standardized anomaly index (SAI) for annual precipitation (SAI(Pr)) and mean temperature (SAI(Tm)) was calculated using their monthly records at sixteen meteorological stations scattered throughout Iran during 1951-2010. The results showed: (1) statistically significant (p < 0.05) drying trends in annual PDI values at most of the stations, primarily accompanied by substantial increases in annual SAITm; (2) considerable positive and negative relationships of annual PDI with annual SAI(Tm) and SAI(Pr), respectively; (3) the 1970s/2000s as the predominant humid/dry decade; (4) More frequent drought than humidity events at similar to 81% of stations; (5) the longest drought was 13 years (1998-2010) seen at the Kermanshah station, with the semi-dry climate in the west of Iran; and (6) the 2010 drought spatially extended over all the stations studied throughout the country. In conclusion, the PDI acceptably succeeded to characterize annual droughts in Iran previously captured by other prominent recommended drought indices.
