Palmer's drought indices revisited

Auteurs :

Description :
Palmer's Hydrological and Meteorological Drought Severity Indices are reviewed along with a number of recent modifications that help reduce ambiguity from decision concerning the beginning and ending of drought conditions. Based on data from Regina, Saskatchewan, it is shown that the Meteorological Index, due to its greater sensivity, responds at least one month faster to changing moisture conditions than the Hydrological Index and is consequently recommended for forward planning in water resource management and agriculture.
