Delhi AQ Summary : SHORT RANGE FORECAST : The overall Delhi AQI is in the higher-end of the very poor category. Calm surface winds are forecasted to continue for the next three days. The SAFAR model forecast suggests AQI to be in the same higher-end of very poor for tomorrow. Under the calm, cold moist conditions dense fog is likely for the next 24 hrs. No significant improvement in AQI from the very poor category is expecting for the 9th December. Marginal improvement in AQI is expecting on 10th December but within the very poor category. Few biomass fire counts are observed, no significant biomass fire PM2.5 contribution is expecting for the coming days. EXTENDED RANGE OUTLOOK: As per the SAFAR-extended range warning model, Delhi's air quality is entering under the influence of RADIATIVE FOG. A fresh western disturbance is likely to affect northwest India by 11th December and likely to change the calm condition and improve ventilation and air quality and scattered rainfall is expected on 12th December, likely to positively influence Air quality.
