Topic: Important Geophysical phenomena such as earthquakes, Tsunami, Volcanic activity, cyclone etc., geographical features and their location-changes in critical geographical features (including water-bodies and ice-caps) and in flora and fauna and the effects of such changes.
1. What is the significance of relative humidity and wet-bulb temperature in predicting and mitigating the impact of heatwaves? How can this knowledge be used to design more resilient buildings and cities in the face of increasing heatwave events? Elucidate with suitable examples. (250 words)
Difficulty level: Moderate
Reference: The Hindu
Why the question:
Relative humidity is a simple concept as weather phenomena go – but it has significant, far-reaching consequences for how we must take care of ourselves on a hot or wet day.
Key Demand of the question:
To write about relative humidity, wet-bulb temperature, and its role in making buildings and cities heatwave resilient.
Directive word:
Elucidate – Give a detailed account as to how and why it occurred, or what is the context. You must be defining key terms wherever appropriate and substantiate with relevant associated facts.
Structure of the answer:
Introduction:
Start by defining relative humidity.
Body:
In the first part of the body, write about the significance – Relative humidity and wet-bulb temperature and their role in designing heat wave resilient buildings – crucial factors in predicting and mitigating the impact of heatwaves on human health and well-being, as well as on energy efficiency and sustainability.
In the next part, write about the significance of the above with suitable examples from across the world.
Conclusion:
Conclude by writing about measures that must be taken to tackle heatwaves in India.
