Abstract: Abrupt weather phenomena, including heat waves, frequent intense storms, outbreaks of forest fires, glacier melting, and flash floods are experienced throughout the world. Pakistan lies in the South Asian region that falls in the monsoon climatic regime, experiencing summer rainfall. The city of Karachi, which is also highly urbanized situated in southern Sindh and receives secondary monsoon rainfall from the month of July to September. During the 1960s, the city received appreciable rainfall during the monsoon, but the amount of rainfall started declining during the 1980s. At the end of the 20th century, the rainfall pattern was quite abrupt, associated especially with the passage of cyclones, which developed in the Arabian Sea and, after touching Oman, reached Karachi, or, moving from Gujrat in India, reached Karachi. So, the rainfall which received annually is now received within a day. The study represents the statistical analysis as well as the GIS and remote sensing perspective of the changing patterns over the last fifty years.
