Impact of ENSO on Summer Monsoon in Southern Parts of Pakistan

The impact of ENSO (El-Nino/Southern Oscillation) on summer monsoon rain fall in southern parts of Pakistan is studied for deeply understanding the characteristics of summer rainfall variation and factors causing severe water shortages in already drought prone regions. The 16 stations data of summer rainfall, sea surface temperature and ENSO during 1951-2000 has been analyzed. The results comparing the rainfall and SST anomaly during the period leads to the idea that the all ENSO events are not essentially correlated with the poor monsoon in southern parts of Pakistan. The research results show that the relationship among ENSO, summer monsoon and drought is uncertainty. Further research is needed to pay attention to find the key factor of impact on summer monsoon rain fall in southern parts of Pakistan for attribution and development of better forecasting techniques for planning and development in the region.
