Summary:The spatiotemporal characteristics of meteorological droughts in the Central Anatolia, a semiarid region in Turkey, are determined utilizing the Standardized Precipitation Index (SPI) as a measure for drought severity. Using the temporal and spatial characteristics of monthly SPI, drought intensity-areal extent-frequency curves for various return periods are constructed for the region, and then the spatiotemporal characteristics of selected historical droughts are evaluated. The results indicate that the region is usually under the influence of droughts with low return periods, in other words, high frequency droughts during the study period (from 1953 to 2004). However, the areal extent of drought may be significant because of its negative impact on the water resources in the region. The overall evaluation of study results reveal that this method can provide useful information for spatial and temporal variations of droughts and can be utilized for water resources management in this region.
