Quick Revision: Tropical cyclones are intense low-pressure systems over warm oceans, requiring robust disaster management strategies encompassing early warning, evacuation, and technology-aided response mechanisms for effective mitigation of their impact on vulnerable coastal regions.

Why is this in the news?

Severe Cyclonic Storm ‘Murasu’ made landfall near Ongole, Andhra Pradesh, prompting extensive preparedness measures by the state government, including the activation of dedicated helplines and coordination with district administrations. The cyclone’s formation in the Bay of Bengal and subsequent intensification necessitated the evacuation of vulnerable populations and the cancellation of flights, highlighting the critical importance of robust disaster management frameworks.

Background

• Tropical cyclones are intense low-pressure systems forming over warm tropical oceans, characterised by strong winds and heavy rainfall, often leading to significant destruction upon landfall.
• The Bay of Bengal is one of the world’s most active regions for tropical cyclone formation, particularly during the pre-monsoon (April-June) and post-monsoon (October-December) seasons.
• The India Meteorological Department (IMD) is the nodal agency responsible for monitoring, forecasting, and issuing warnings for tropical cyclones in the North Indian Ocean region.
• Coastal states in India, such as Andhra Pradesh, Odisha, and Tamil Nadu, are highly vulnerable to cyclones, necessitating well-established disaster preparedness and response protocols.
• Early warning systems, including satellite imagery, radar, and numerical weather prediction models, are crucial for timely dissemination of information to affected populations and disaster management agencies.
• The National Disaster Management Authority (NDMA) provides guidelines and policies for disaster management, while State Disaster Management Authorities (SDMAs) implement these at the state level, often supported by district-level committees.

Understanding Tropical Cyclones and Disaster Management

• Tropical cyclones are rotating storm systems characterised by a low-pressure centre, strong winds, and heavy precipitation, deriving energy from the latent heat of condensation over warm ocean waters.
• Their formation requires specific conditions: sea surface temperatures above 26.5°C, sufficient Coriolis force, low vertical wind shear, and pre-existing low-level disturbance.
• The IMD classifies cyclones based on their maximum sustained surface wind speed, ranging from ‘Depression’ to ‘Super Cyclonic Storm’.
• Disaster management encompasses a cycle of preparedness, response, recovery, and mitigation, aiming to reduce the impact of natural hazards.
• Preparedness activities include developing early warning systems, conducting mock drills, stockpiling essential supplies, and establishing evacuation plans.
• Response mechanisms involve search and rescue operations, providing immediate relief, medical assistance, and restoring essential services like power and communication.
• The ‘Mana Mitra’ WhatsApp Governance platform, as deployed by the Andhra Pradesh government, exemplifies the use of technology for real-time grievance redressal and citizen-administration communication during emergencies.
• Inter-state cooperation and coordination, as observed in Andhra Pradesh seeking assistance from Tamil Nadu and Karnataka for power restoration, are vital for effective regional disaster response.

Challenges — UPSC Perspective

Way Forward

• Strengthen early warning systems and meteorological forecasting capabilities to provide more accurate and timely cyclone predictions.
• Invest in resilient infrastructure development, including underground cabling for power lines and cyclone-resistant housing, particularly in coastal regions.
• Enhance community preparedness through regular drills, awareness campaigns, and training programs for local disaster response teams.
• Leverage technology further by integrating AI and data analytics into disaster management platforms for predictive analysis and resource optimization.
• Establish robust inter-state and central-state coordination mechanisms for rapid deployment of resources and personnel during large-scale disasters.
• Develop comprehensive post-disaster recovery frameworks that include livelihood restoration, psychological support, and long-term economic rehabilitation.
• Promote ecological restoration of coastal ecosystems, such as mangroves, which act as natural barriers against storm surges and coastal erosion.

UPSC Value Addition

Prelims Practice Questions

Q1. Consider the following statements regarding cyclone management in India:
