Delhi winter pollution could be worse this year
Delhi is bracing for potentially worse winter pollution this year, with the annual stubble-burning season already underway in north India. Satellite data reveals 47 farm-fire incidents between September 15 and 23, primarily in Punjab and Uttar Pradesh. However, the situation could be more complicated due to an expected El Nino event, which may reduce the frequency of western disturbances – weather systems that can temporarily clear pollutants.
Weaker winds and delayed monsoon rains could lead to pollutant accumulation. The Diwali festival and peak farm-fire activity are set to coincide, potentially exacerbating the issue. While farm fires have decreased in some states, others like Uttar Pradesh have seen an increase. Authorities are monitoring the situation closely, but the final air quality assessment will depend on factors like enforcement, residue management, and weather conditions as the season progresses.
