Q2. How do oceanic and atmospheric factors collectively influence the Indian summer monsoon? Why are sub-continental parameters becoming increasingly decisive? (10 M)
Difficulty Level: Medium
Reference: TH
Why the question The 2025 IMD monsoon forecast, highlights both traditional oceanic indicators and rising importance of regional factors like snow cover and cyclonic activity. Key Demand of the question To examine how oceanic and atmospheric systems influence the Indian monsoon as a whole, and explain the growing role of sub-continental and regional elements in shaping rainfall outcomes. Structure of the Answer: Introduction Mention India’s monsoon as a globally influenced yet regionally modulated system, and the shift in recent years toward localised drivers. Body Explain the role of major oceanic and atmospheric factors such as ENSO, IOD, and MJO. Analyse why sub-continental factors like Eurasian snow cover, cyclonic activity, and land heating are becoming more influential in determining monsoon characteristics. Conclusion Suggest the need for integrating regional predictors into India’s forecasting systems to enhance monsoon resilience.
