These data were compared with the corresponding observations of SOI (Southern Oscillation Index).In case of depression and cyclonic storm there have significantly no variation for ENSO conditions but 54 severe cyclonic storms were formed during El Nino and 77 during La Nina condition in 100 years. Major 7 floods of Bangladesh having more than 35% affected area were identified. There was very excessive rainfall for the floods of 1955, 1974, 1987, 1988, 1998,...
