摘要：
Bangladesh is experiencing a more rapid warming trend compared to the global average, facing significant climate-related risks. This study gave a comprehensive assessment of rainfall variability across the whole Bangladesh during 1989-2022. Annual rainfall in Bangladesh exhibited significant decreasing trends and high oscillation patterns. The multi-scale SPI and SPEI analysis revealed that Bangladesh experienced severe droughts in 1995, 1999, 2018, 2021 and 2022. The DFA revealed that rainfall evolution exhibited significant long-term positive correlation in almost Bangladesh. These results will support policymakers in Bangladesh to develop suitable strategies in mitigating climate change impacts.
