Q2. Discuss the role of Western Disturbances in India’s winter rainfall. Why did the higher-than-normal number of Western Disturbances fail to deliver significant rainfall in India recently? (10 M)
Difficulty Level: Medium
Reference: DTE
Why the question India has experienced a dry winter season (January-February) in 2025, with 89 per cent of districts suffering from deficient, large deficient, or no rainfall, according to data from the India Meteorological Department (IMD). Key demand of the question The question requires an explanation of the role of western disturbances in India’s winter rainfall and an analysis of why, despite a higher number of disturbances, they failed to deliver significant precipitation in 2025. Structure of the answer Introduction Briefly define western disturbances and their significance in India’s winter weather patterns, highlighting their crucial role in precipitation over northwestern and central India. Body Role of western disturbances in winter rainfall – Explain their contribution to rainfall, snowfall, and temperature moderation in northern and central India. Reasons for failure in 2025 – Discuss the factors such as lack of moisture incursion, weak upper-level troughs, high-pressure blocking, El Niño effects, and shifting trajectories that led to minimal precipitation. Conclusion Conclude by linking the failure of western disturbances to climate change and atmospheric variability, emphasizing the need for adaptive strategies in agriculture and water resource management.
