Abstract

Drought had been observed as a recurrent disaster which gradually becomes a usualphenomenon of a region. Severe environmental, economic and social impacts for the victims had beenseen. Adverse impact of meteorological drought could be curtailed to a minimum only through properplanning and drought mitigation measures. This research study offered comparison of threeinterpolation methods which were used to create meteorological drought intensity surfaces. This studydelineated the pattern of meteorological drought intensity in Pakistan during1980-2010. Three mapswere developed using three different interpolation methods and specific semivariograms. It wasconcluded that the Spline method using tension semivariogram presented meteorological droughtpicture for Pakistan, which appeared to be much closer to the classification of droughts given by thegovernment of Pakistan for the drought 2000-01.
