Tropical cyclones are rapidly rotating storm systems characterized by a low-pressure center, atmospheric instability, and a spiral arrangement of severe thunderstorms. In coastal geographic zones—particularly along the highly exposed Bay of Bengal and the coastal belt of Cox’s Bazar—these systems pose a recurring, existential threat. Driven by the transfer of thermal energy from warm ocean waters to the atmosphere, the destructive potential of cyclones is being fundamentally magnified by global climate change. Elevated sea surface temperatures are increasingly causing these storms to undergo rapid intensification, resulting in a higher frequency of severe-category cyclones with unprecedented wind velocities. Furthermore, climate-induced sea-level rise dramatically exacerbates the reach and lethality of cyclone-driven storm surges, pushing saltwater deeper inland, contaminating vital freshwater aquifers, and causing catastrophic inundation. The cascading impacts of these events decimate power grids and transportation infrastructure, wipe out agricultural yields through acute soil salinity, and trigger complex public health emergencies. Transitioning from coastal vulnerability to robust climate resilience requires a comprehensive, multi-layered adaptation strategy. This encompasses the targeted expansion of multi-purpose cyclone shelters, the deployment of satellite-integrated, hyper-localized early warning networks—exemplified by frameworks like the Cyclone Preparedness Programme (CPP)—and the strict enforcement of climate-adaptive building codes. Equally critical is the prioritization of nature-based solutions, specifically the preservation and restoration of mangrove ecosystems, which serve as frontline bio-shields to dissipate wave energy and significantly blunt the inland impact of massive storm surges.
