India’s winter weather is becoming increasingly erratic, marked by freezing cold spells, unseasonal rain and persistent fog across many regions. Scientists explain that these unusual patterns are linked to changes in Western Disturbances, the weather systems that normally bring winter rain and snowfall to northern India and the Himalayas.
Western Disturbances have traditionally played a crucial role in sustaining winter crops, replenishing groundwater and maintaining Himalayan snowpack. However, climate change is now altering their behaviour — affecting their timing, strength and movement. As global temperatures rise, atmospheric circulation patterns are shifting, leading to sudden temperature fluctuations, excessive fog formation and unpredictable rainfall during winter months.
This disruption has serious consequences. Farmers face crop damage and yield uncertainty, transport systems are affected by poor visibility, and urban populations struggle with prolonged cold and air stagnation. What is unfolding is not an isolated weather anomaly but a clear signal of climate instability driven by human-caused global warming. India’s experience this winter shows how deeply climate change is reshaping even long-established seasonal patterns, demanding urgent action focused on climate resilience and emission reduction.
