2011 North Indian cold wave

The 2011 North Indian cold wave was a significant weather event that affected northern India during the winter months, primarily in January 2011. Characterized by a severe drop in temperatures, the cold wave resulted in widespread disruptions, notably impacting daily life, agriculture, and transportation. Areas such as Punjab, Haryana, Delhi, and Rajasthan experienced sub-zero temperatures, with some regions recording near-historic lows. The cold wave was attributed to a combination of factors, including a prolonged western disturbance and the retreat of the Himalayan snow cover, which intensified the chilling effects across the region. The adverse conditions led to numerous fatalities, particularly among vulnerable populations, and prompted alerts from meteorological agencies for protective measures.
