The airquality overDelhi-NCT likely to remain in Poor category today

According to the National Weather Forecasting Centre of the India Meteorological Department (IMD):

Wind Pattern and Ventilation Index Forecast

Air mass inflow forecast in Delhi along with predicted ventilation co efficient and weather forecast is as follows:

1. The airquality overDelhi-NCT is likely to remain in Poor category on 02.07.2021.PM10 will be the predominant pollutant owing to strong surface winds favourable forraising dust concentration locally and transport of dust from arid regions. The air qualityis likely to deteriorate owing to strong winds/dust storms and reach in upper end of Poorcategory on 03.07.2021. The air quality is likely to improvemarginally on 04.07.2021but remain in Poor to Moderate category. The Outlook for subsequent 5 Days: The air quality is likely to remain largely in Moderate category.

2. The predominant surface wind is likely to be coming from West/Southwest directions ofDelhi with wind speed 15-18 kmph, partly cloudy sky, heat wave conditions at isolatedplaces, dust storm/thunderstorm accompanied with very light rain and gusty winds (speed40-50 kmph on 02.07.2021. The predominant surface wind is likely to be coming fromWest directions of Delhi with wind speed 12-15 kmph, partly cloudy sky and possibilityof very light rain/thundershowers on 03.07.2021. The predominant surface wind is likelyto be coming from West directions of Delhi with wind speed 12-15 kmph, partly cloudy sky and possibility of thundery development on04.07.2021.

4. Predicted maximum mixing depth is likely to be approx. 4300 m on 02.07.2021, 1300 mon 03.07.2021 and 3500 on 04.07.2021 over Delhi. Maximum Ventilation index is likely to be approx.21000m²/son02.07.2021,14000m²/s03.07.2021and14500m²/s04.07.2021. The ventilation index lower than 6000 m²/s with average wind speed lessthan10kmph is unfavourable or dispersion of pollutant.
