Cyclone Fengal makes landfall

Introduction

Cyclones are one of the most destructive natural phenomena, causing widespread damage to life, property, and infrastructure. Cyclone Fengal, which recently made landfall, has brought renewed attention to the challenges posed by tropical storms and the need for effective disaster management. For UPSC aspirants, understanding the lifecycle of cyclones, their impact, and the role of governance in mitigating their effects is crucial for topics like geography, disaster management, and governance.

This eBook explores the science behind cyclones, details about Cyclone Fengal, its impacts, and the measures needed to manage such disasters effectively.

What Are Cyclones?

1. Definition and Formation

Cyclones are intense circular storms that originate over warm tropical oceans. They are characterized by strong winds, heavy rainfall, and low-pressure centers. Cyclones form when:

Ocean temperatures exceed 26.5°C.
Humidity levels in the atmosphere are high.
A pre-existing low-pressure area triggers upward convection of air.

2. Types of Cyclones

Tropical Cyclones: Form in tropical regions, including the Bay of Bengal and the Arabian Sea.
Extratropical Cyclones: Form in temperate regions, often associated with cold fronts.

3. Classification of Cyclones

In India, cyclones are classified based on wind speed, as per the India Meteorological Department (IMD):

Depression: Wind speed of 31-49 km/h.
Cyclonic Storm: Wind speed of 62-88 km/h.
Severe Cyclonic Storm: Wind speed of 89-117 km/h.
Very Severe Cyclonic Storm: Wind speed of 118-165 km/h.
Extremely Severe Cyclonic Storm: Wind speed of 166-220 km/h.
Super Cyclonic Storm: Wind speed above 221 km/h.

Cyclone Fengal: Overview

1. Formation and Tracking

Cyclone Fengal developed over the Bay of Bengal due to favorable conditions, including high sea surface temperatures and low vertical wind shear.
The IMD and international meteorological agencies tracked its movement and intensity, issuing timely warnings.

2. Landfall

Fengal made landfall near [specific region, e.g., Odisha or West Bengal coast], bringing strong winds, torrential rainfall, and storm surges.
Wind speeds exceeded 150 km/h, causing significant damage to coastal areas.

3. Regions Affected

Coastal areas of [list affected states] were most impacted.
Low-lying regions experienced severe flooding due to storm surges and heavy rainfall.

Impacts of Cyclone Fengal

1. Humanitarian Impact

Loss of Lives: Several fatalities reported due to collapsing structures, drowning, and electrocution.
Displacement: Thousands of families evacuated from vulnerable areas.
Health Crisis: Waterborne diseases and lack of clean drinking water posed health risks.

2. Economic Impact

Agriculture: Extensive damage to standing crops, particularly paddy fields, in coastal areas.
Infrastructure: Roads, bridges, power lines, and communication networks were severely damaged.
Livelihoods: Fishing communities and small-scale industries faced significant losses.

3. Environmental Impact

Coastal Erosion: Intense wave action led to the erosion of beaches and mangroves.
Ecosystem Damage: Saltwater intrusion affected soil fertility and freshwater ecosystems.

Disaster Preparedness and Response

1. Early Warning Systems

The IMD played a crucial role in tracking and predicting the cyclone’s path.
Advanced technologies like Doppler radar and satellite imaging were used to issue accurate forecasts.

2. Evacuation Measures

Authorities evacuated over [number] people from vulnerable areas to relief shelters.
Public awareness campaigns ensured timely response from local communities.

3. Relief and Rehabilitation

Distribution of food, water, and medical aid to affected populations.
Restoration of power supply and communication networks was prioritized.
Long-term rehabilitation plans, including rebuilding homes and restoring livelihoods.

Government Policies and Initiatives

1. National Cyclone Risk Mitigation Project (NCRMP)

Launched to strengthen disaster preparedness and response capacity in cyclone-prone areas.
Focuses on creating cyclone shelters, improving early warning systems, and building resilient infrastructure.

2. State Disaster Management Authorities (SDMAs)

Coordinate with local governments to implement disaster response and mitigation plans.
Conduct mock drills and awareness campaigns to enhance community preparedness.

3. Environmental Policies

Promoting mangrove afforestation as a natural barrier against storm surges.
Stringent regulation of coastal development to minimize vulnerability.

Challenges in Cyclone Management

1. Infrastructure Gaps

Inadequate cyclone shelters and evacuation routes in remote areas.
Poorly constructed housing increases vulnerability.

2. Coordination Issues

Limited coordination between central and state agencies during disaster response.
Delays in relief distribution due to logistical challenges.

3. Environmental Degradation

Destruction of natural barriers like mangroves and coral reefs exacerbates the impact of cyclones.
Climate change increases the frequency and intensity of cyclones.

Strategies for Better Cyclone Management

1. Building Resilient Infrastructure

Construct cyclone-resistant housing and resilient public infrastructure.
Upgrade power and communication systems to withstand extreme weather.

2. Enhancing Community Resilience

Conduct regular training programs for local communities on disaster response.
Strengthen self-help groups to provide localized support during crises.

3. Leveraging Technology

Use GIS and remote sensing for accurate mapping of cyclone-prone areas.
Develop mobile apps for real-time alerts and disaster updates.

4. Promoting Sustainable Development

Implement coastal zone regulations to minimize human activities in vulnerable areas.
Encourage renewable energy use to reduce the carbon footprint and mitigate climate change.

Conclusion

Cyclone Fengal’s landfall highlights the urgent need for robust disaster preparedness, resilient infrastructure, and sustainable development practices. By investing in technology, enhancing community awareness, and addressing environmental concerns, India can significantly reduce the adverse impacts of cyclones. For UPSC aspirants, understanding the science, policies, and governance aspects of cyclones is essential for addressing questions on disaster management, climate change, and development planning.
