Topic: Important Geophysical phenomena such as earthquakes, Tsunami, Volcanic activity, cyclone etc.,
Q1. Discuss the role of marine heatwaves in shaping the intensity and destructiveness of tropical cyclones. Analyse their impact on coastal ecosystems. Suggest measures for climate-resilient coastal planning. (15 M)
Difficulty Level: Medium
Reference: DTE
Why the question
Growing scientific evidence linking marine heatwaves with intensified cyclones and rising coastal risks makes it a critical contemporary geography theme under climate change.Key Demand of the question
The question requires linking oceanic thermal anomalies with cyclone dynamics, examining ecological consequences on coastal systems, and suggesting planning measures for resilience. It tests conceptual clarity, analytical linkage, and applied solutions.Structure of the Answer:
Introduction
Briefly introduce marine heatwaves as an emerging oceanic phenomenon influencing extreme weather and coastal vulnerability.Body
- Role in cyclone intensity: Explain how marine heatwaves enhance energy supply leading to rapid intensification and higher destructiveness.
- Impact on coastal ecosystems: Show how intensified cyclones and thermal stress degrade coral reefs, mangroves, and biodiversity.
- Measures for coastal planning: Suggest integration of forecasting, ecosystem restoration, resilient infrastructure and regulatory planning.
Conclusion
End with a note on integrating ocean science with climate-resilient coastal governance.
