Cue from past: Why Delhi is unlikely to face brunt of farm fires in much of October

Experts predict that Delhi's air quality will oscillate between 'moderate' and 'poor' as the peak stubble burning season approaches. Although stubble burning in Punjab is currently limited, a combination of factors including wind speed, wind direction, and transport winds at a specific height are needed for the fire pollutants to significantly impact Delhi's air quality. The pollution particles have a short lifespan and settle on the ground within a day or two. Therefore, a delicate balance in wind conditions is necessary for intrusion into Delhi's atmosphere.
