Topic: Salient features of world’s physical geography.
Q2. How has the Southern Oscillation enhanced the understanding of the Indian monsoon? Assess its significance for weather forecasting. (10 M)
Difficulty Level: Medium
Reference: IE
Why the question
The Southern Oscillation is one of the most important atmospheric phenomena influencing the Indian monsoon and laid the foundation for modern monsoon forecasting. Its relevance continues in the context of climate variability and weather prediction.
Key Demand of the question
The question requires explaining how the Southern Oscillation improved the scientific understanding of the Indian monsoon and assessing its contribution to weather forecasting and prediction systems.
Structure of the Answer:
Introduction
Briefly define the Southern Oscillation as a large-scale atmospheric pressure fluctuation and mention its importance in understanding global climate linkages affecting the Indian monsoon.
Body
- Enhanced understanding of the Indian monsoon: Explain how the Southern Oscillation revealed the connection between monsoon behaviour and broader atmospheric-oceanic processes.
- Significance for weather forecasting: Show how knowledge of the Southern Oscillation improved seasonal forecasting, prediction models and climate preparedness.
Conclusion
Conclude by highlighting that the Southern Oscillation remains a key pillar of monsoon science, though forecasting accuracy increasingly depends on integrating multiple climatic factors in a changing climate.
