Abstract:

Summer monsoon rainfall is a major driver of the environmental and agricultural functioning in south Asia. This investigative study is carried out to sketch a precise picture of temporal trends in the peak monsoon rainfall events over Northeast Pakistan. Daily rainfall observed data from PMD for the period 1961-2010 is analyzed to investigate the temporal trends on monthly as well as weekly basis at the selected stations of the northeast monsoon regime. Frequency of extreme rainfall events with 50 mm, 100 mm and 150 mm or more rainfall is calculated. Islamabad is found to enjoy the highest frequency of 50 mm and 100 mm or more precipitation events. In case of 150 mm or heavier events Sialkot is the one with highest frequency. August is the month with the highest frequency of peak rainfall events. Last week of July along with the first two weeks of August are the most probable time for the occurrence of peak rainfall events of the season. The study of temporal trends in the peak monsoon rainfall events over Northeast Pakistan is very significant in its consequences for planning purposes in water resource management.
