Although no direct correlation has been found between the Southern Oscillation and consequent temperature anomaly in the oceanic systems and the extreme weather events in Bangladesh, some studies report that the El Nino Southern Oscillation (ENSO) events influenced the record-breaking floods of 1987, 1988 and 1998. The rapid transformation of La Nina from El Nino phase in early monsoon in 1998 is said to have influenced high rates of precipitation over the entire GBM catchments basin. As a result, after a prolonged dry season, the wettest monsoon came along with extremely high levels of precipitation eventually resulting in the deluge of the century. Such global events could therefore intensify some of the extreme climate change related weather events even further.
