North India experienced a warm and dry winter attributed to weak Western Disturbances (WDs).
GK and monthly revision
Weak western disturbances and shifting jet stream drive warm, dry winter in North India
North India experienced an unusually warm and dry winter primarily due to weak Western Disturbances and a shifting jet stream. This climatic anomaly, driven by altered upper-level winds, has significantly suppressed crucial rain and snowfall over the Himalayas. The resulting dry conditions are also contributing to worsening air quality across the north-west, making understanding these meteorological phenomena vital for competitive exams focusing on Indian geography and environment.
