The Palmer drought index, more fully known as the Palmer drought severity index, is a regional index used to monitor drought conditions and to study how far a drought extends and how severe it is. It works from a simple water balance model that draws on precipitation and temperature data to assess the supply of and demand for moisture in an area. The index was developed by meteorologist Wayne Palmer, who first published his method in a 1965 paper, Meteorological Drought, written for the Office of Climatology of the United States Weather Bureau.
