RECENT SUMMER HEATWAVE IN BANGLADESH ENHANCED BY ATLANTIC MULTI-DECADAL OSCILLATION AND LARGE-SCALE ATMOSPHERIC FACTORS

Overview & Synopsis

The substantial change in climate regime observed in Bangladesh after 1999, characterized by a pronounced slope and significant correlation with the AMO, highlights the vulnerability of the region to climate variability. The ERA5 reanalysis data reveal key changes in the large-scale atmospheric circulation, including enhanced anticyclonic formations, escalating air temperatures, increased relative humidity, and intensified cloudiness. These changes have cumulatively exacerbated summer heat waves in Bangladesh, underscoring the urgent need for adaptive strategies aimed at mitigating the impacts of these climatic transitions on local populations and ecosystems. Future research should prioritize the impacts of these changes and prospective adaptation strategies to strengthen resilience in the face of continued climate variability.
