NEW DELHI:  Delhi is likely to breathe a bit easy on Sunday as System of Air Quality and Weather Forecasting and Research (SAFAR) on Saturday said the national capital’s Air Quality Index (AQI) was likely to improve to the upper end of the very poor category as surface winds were becoming stronger, dispersing air pollutants.

As per the SAFAR, strong north westerly winds enhanced the transport of emissions from stubble burning. Share of crop residue burning emissions in PM2.5 was 41 per cent. The air quality forecast agency noted that the effective fire count reported on Saturday till evening was 5,159.

The agency noted that there were five most Influencing factors forecasted to deteriorate AQI in Delhi which are stubble burning, external dust intrusion, mixing layer height, local wind speed and ventilation.
As per CPCB, at 4 pm the index value remained at 437 which falls under the severe category. On Friday, the AQI stood at 462. According to weather scientists, fog/smog conditions on November 6 morning have improved in Delhi NCR as was forecasted.
