More than 80% of Pakistan land is arid or semi arid. A dust storm is a meteorological phenomenon common on the arid and semi arid regions of the world. In this paper, normal dust storms frequency (1961-1990) over various meteorological stations of Pakistan situated in Punjab, Sindh, North Western Frontier Province, Balochistan and Northern Areas & Azad Jammu & Kashmir is discussed on seasonal as well as annual basis. The mean annual dust storms frequency (1991-2000) is compared with the normal annual frequency (1961-1990) and the dust storms frequency trend during 1991-2000 is also discussed. The graphical representation of the data is also given. The same is also shown in the form of maps (A to G) prepared by using Geographical Information System soft wares Arcview3.2 and ArcGIS at Institute of Geographical Information Systems, National University of Science & Technology, Islamabad.
