Major Floods and Tropical Cyclones over Bangladesh: Clustering from ENSO Timescales

The present study analyzed major floods and tropical cyclones (TCs) over Bangladesh on El Niño-Southern Oscillation (ENSO) timescales. geographical location, low almost flat topography have introduced as one of the most vulnerable countries world. is highly to extreme hazard events like which are impacted by ENSO. ENSO mainly a event, but its impact global. Niño (La Niña) represents warm (cold) phase cycle. Rainfall cyclonic disturbances data been used for period 70 years (1948–2017) compared with corresponding observations Southern Index. Result shows that flood occurred during monsoon period, them La Niña condition, consistent historical archives in Bangladesh. Synoptic conditions these well matched condition. On other hand, TC cases either pre-monsoon or post-monsoon season. under neutral (developing Niña, climatology studies favorable more intense TCs Bay Bengal.
