Context
A deep depression in the Bay of Bengal has intensified into cyclonic storm 'Murasu', which is predicted to become a very severe cyclonic storm. It is expected to make landfall on the Andhra Pradesh coast, prompting high alerts and evacuation orders in the southern regions of Odisha. This event highlights the recurring vulnerability of India's eastern coast to tropical cyclones and the critical need for robust disaster preparedness mechanisms.
UPSC Perspectives
Geographical
The formation of Cyclone Murasu over the is a classic example of tropical cyclogenesis, a process requiring specific conditions: sea surface temperatures above 26.5°C, high humidity, and sufficient Coriolis force to create a low-pressure vortex. The Bay of Bengal is particularly prone to such formations due to its unique topography and warmer waters compared to the Arabian Sea. Murasu's projected intensification into a very severe cyclonic storm implies wind speeds of 118-166 kmph, posing significant risks of storm surges and widespread damage. The naming of the cyclone by India underscores the regional cooperation framework overseen by the for identifying and tracking these systems. UPSC aspirants should study the favorable conditions for cyclone formation, the stages of cyclone development (from low pressure to severe cyclonic storm), and the geographical reasons why the eastern coast of India is more vulnerable than the western coast.
Governance
The proactive response of the Odisha government, including issuing high alerts and initiating evacuations, demonstrates the operationalization of the . This legal framework mandates a decentralized approach to disaster response, empowering state and district authorities. The crucial role of the (IMD) in providing accurate, early warnings is essential for activating state-level protocols. Successful disaster management hinges on the 'Golden Hour'—the immediate period after a warning where swift action can minimize casualties. Evacuating vulnerable populations from low-lying areas, as ordered in Odisha, is a key strategy for mitigating the impact of severe weather events. For UPSC Mains, analyzing the effectiveness of India's early warning systems and the implementation of standard operating procedures at the state level is vital.
Environmental
The increasing frequency and intensity of severe cyclonic storms in the Bay of Bengal are increasingly linked to the impacts of climate change. Rising global temperatures lead to warmer sea surface temperatures, providing more energy for tropical cyclones to intensify rapidly. Furthermore, global warming contributes to sea-level rise, exacerbating the destructiveness of storm surges upon landfall. The threat posed by Cyclone Murasu necessitates a long-term focus on climate resilience and adaptation strategies. Coastal communities must be empowered with robust infrastructure, improved forecasting systems, and diversified livelihoods to withstand the changing climate reality. A UPSC perspective requires analyzing how global environmental changes translate into localized disaster risks, emphasizing the need for comprehensive adaptation policies to protect vulnerable coastal regions.
