Drought is universally acknowledged as a phenomenon associated with scarcity of water. The Standardized Precipitation Index (SPI) expresses the actual rainfall as standardized departure from rainfall probability distribution function. In this study severity and spatial pattern of meteorological drought was analyzed in the Anantapuramu District, Andhra Pradesh, India using multi-temporal SPI. Monthly data for the period 1988-2017 from 5 rainfall stations surrounding the study area were collected from IMD, Hyderabad, and used in the analysis. Temporal analysis was used to generate drought severity for the different time scales and months of the year. Temporal SPI graphs show that the maximum SPI value (extreme drought) occurs in station 5 in the year 1991. Mild and moderate droughts occur in the central portion of the study area. Severe and extreme droughts were mostly found in the region.
