In this research, the standard precipitation index (SPI) was used to analyze rainfall records between 1941 - 2002 for nine metrological stations in the north of Iraq. In addition, digital maps of average drought magnitude and average drought intensity for the study region had drawn by using geographic information system (GIS). It is concluded that 56% of the study period were drought years.
