Delhi Air Quality Predicted to Reach 'Severe' Category Amid Rising Pollution
Delhi is forecasted to experience 'severe' air pollution levels for the first time this season due to slow winds and falling temperatures, which aid pollutant accumulation. The city's Air Quality Index (AQI) was 366 ('very poor') on Sunday, with some monitoring stations already reporting 'severe' readings. Paddy stubble burning in Punjab and vehicle restrictions are factors influencing air quality.
Delhi’s air pollution is expected to worsen, reaching the 'severe' category (AQI 400+) this week, marking the first such occurrence this season. According to the Indian Institute of Tropical Meteorology, slow winds and lower temperatures will promote the buildup of pollution as the city transitions from slightly above normal temperatures to cooler weather patterns. On Sunday, the AQI was measured at 366, categorized as 'very poor,' though morning readings at 18 out of 39 air quality stations indicated 'severe' pollution before settling later in the day. The forecast includes shallow morning fog, which can further trap pollutants near the surface. Increased paddy stubble burning in Punjab, reported at nearly 500 incidents on Saturday due to crop harvest completion, heavy rains, and grain discolouration, is expected to exacerbate pollution levels. Additionally, curbs on commercial vehicles with BS III and BS IV engines were imposed starting Saturday to control vehicular emissions. These combined factors suggest an escalating air emergency in Delhi, with significant health risks anticipated as winter conditions begin to favor pollutant accumulation.
