Delhi's air quality improves from very poor to poor as strong winds disperse pollutants
Delhi's air quality improved from 'very poor' to 'poor' on Saturday, with an average air quality index (AQI) of 291. This change followed strong winds that helped disperse pollutants after Diwali celebrations, which had caused significant spikes in pollution levels. On Friday, the AQI reached 339, with PM2.5 levels soaring in some areas due to firecracker use. The winds, blowing at 10-15 km/h, contributed to the reduction in pollution, contrasting with the high levels recorded during the celebrations. Experts expect the winds to continue on Saturday but become calmer on Sunday, which may lead to a rise in pollution levels again. The Central Pollution Control Board categorizes AQI levels, with 0-50 as 'good' and 301-400 as 'very poor'.
