New Delhi, 6th June. According to the National Weather Forecasting Centre of the India Meteorological Department, the air quality over Delhi-NCT is likely to remain in the Moderate category on 6th and 7th June.

The air quality is likely to deteriorate and crossover from Moderate to Poor category on 8th June likely to remain in Moderate to Poor category.
The predominant surface wind is likely to be coming from the Southwest directions of Delhi with wind speed 10-16 kmph and partly cloudy sky with the possibility of exceptionally light rain/drizzle on 06.06.2021. The predominant surface wind is likely to be coming from Northwest/West directions of Delhi with wind speed 16-28 kmph and partly cloudy sky with possibility of noticeably light rain/drizzle on 07.06.2021. The predominant surface wind is likely to be coming from the West directions of Delhi with wind speed up to 28 kmph, mainly clear sky and strong surface winds (speed 25-35 kmph) during the day on 08.06.2021. The predicted maximum mixing depth is likely to be approx 3500 m on 06.06.2021 and 4100 m on 07.06.2021 and 4000 m on 08.06.2021 over Delhi. The maximum Ventilation index is likely to be approx 23000 m2/s on 06.06.2021 and 33000 m2/s on 07.06.2021 and 46000 m2/s on 08.06.2021. The ventilation index lower than 6000 m2/s with an average wind speed less than 10 kmph is unfavourable for dispersion of pollutants. The strong surface winds are favourable for raising dust locally and transport of dust from the nearby region, thereby making PM10 predominant pollutant.
