SHORT RANGE FORECAST: (1) Delhi: The overall air quality is in the high end of the Very Poor category as of today morning as forecasted. Surface-level winds are Southwesterly and moderate. Boundary layer wind direction is North northwesterly and partly favorable for Stubble fire-related transport. Stubble fire counts with sufficient potential as estimated from SAFAR-multi-satellite products significant and around 316. Hence, the Stubble burning share in PM2.5 in Delhi's air is estimated as ~3 % for today. Air quality is likely to marginally improve with in the Very Poor for tomorrow owing slightly better ventilation condition. By 4th December ventilation conditions are likely to slow down again and deterioration in AQI is expected. Higher-end of Very poor category is forecasted for 5th December. (2) Mumbai, Pune, and Ahmedabad: The air quality of Pune, Ahmedabad, and Mumbai are in the Moderate category as on today. FORECAST: Pune: AQI will remain in moderate category; Mumbai: Lowering of temperature and influx of inland polluted air will lead to poor AQI for next two days; Ahmedabad: cold and polluted air north India will lead to moderate to poor AQI.
