Q2. Rising night-time temperatures are redefining India’s climate risk profile more than rising daytime extremes. Examine the climatological basis of this trend. Assess its implications for seasonal heat stress and rainfall variability in India. (15 M)
Difficulty Level: Medium
Reference: DTE
Why the question Rising minimum temperatures are increasingly shaping India’s climate extremes, as reflected in recent IMD climate statements, yet public and policy focus remains largely on daytime heat. Key Demand of the question The question demands an explanation of the climatological basis behind rising night-time temperatures and an assessment of their implications for seasonal heat stress and rainfall variability in India. Structure of the Answer Introduction Briefly indicate the shift from daytime-dominated warming to asymmetric warming driven by rising minimum temperatures and explain why this matters for India’s climate geography. Body Climatological basis: Outline the atmospheric and land-surface processes responsible for faster rise in minimum temperatures. Implications for heat stress: Assess how warmer nights prolong physiological stress and alter seasonal thermal boundaries. Implications for rainfall variability: Examine the role of elevated night-time temperatures in enhancing atmospheric moisture and rainfall intensity across seasons. Conclusion Summarise the significance of night-time warming as a redefining element of India’s climate risk profile and underline the need for its inclusion in adaptation strategies.
