New Delhi: Delhies continued to sigh the deadly toxic gas cocktails with the remaining air quality “severe” for the second day after Diwali, because most pollutants remained trapped in the area even though the wind was picked up for several hours.
Meanwhile, agricultural fire share in PM2.5 city pollution rose to 41% as propellers began to culminate in neighboring countries.
Aqi as a whole in the city saw a marginal increase of 462 on Friday to 437 on Saturday.
Smog appears again in the morning, reducing visibility to 600-800 meters between 5:30 am and 9:30 a.m.
Every last three days have seen parts of the stump-burning at the PM2.5 level of the city touching the new high season.
A small increase can make air quality ‘very poor is 25% on Diwali and 36% on Friday.
According to experts, air quality remains in the zone “severe” mainly due to increasing folk share burning, quiet wind conditions, low temperature, low mixture of low mixture and dust transportation from Rajasthan.
The minimum temperature is 14.7 degrees Celsius, which prevents the spread of high mixing high pollutants making toxic air layers close to the ground level.
Wind speeds increased during the day but the calm conditions were observed later that day, causing pollutant accumulation.
“The wind speed in Safdarjung and Palam reported about 10 to 15kmph until 16:00, which then slowed down became calm or wind.
The direction of the wind remained from the west to north-Northwesterly,” said RK Jenamani, senior scientist at the Indian Meteorology Department (IMD) .
He added, “The condition of the fog / fog improved in Delhi on Saturday morning compared to Friday.
Shallow fog was observed in the range of visibility of 600 to 800 meters in Safdarjung and Palam starting at 5:30 a.m.
to 9:30 a.m.
Then on the day with surviving smoke.
“Mahesh Palawat Weather Skymet, a personal weather forecasting agent, said,” Wind speed was almost calm on Friday night but the wind speed was picked up on Saturday for about four hours, helping dispersion of pollutants.
However, the wind later it slows down but the wind is so fast expected on Sunday.
“Dipankar Saha, former Head of the CPCB air laboratory, said,” low wind speed, high mixing height and low temperatures make pollutants accumulate in the atmosphere.
At the same time, when the wind direction is western.
To the northwest, emissions from Punjab and Haryana and dust from the Rajasthan side are transported to the Delhi region.
“He added that the quality of UD Ara is likely to increase gradually if there is an increase in ventilation, wind speed or high mixing.
Data control space of the central pollution pollution center shows that the average concentration of 24 hours the average Delhi-NCR is 429 micrograms per cubic meter and 298 micrograms per cubic meter, at 7pm.
PM10 and PM2.5 standards are 100 and 60 micrograms per cubic meter, respectively.
With the IMD predicted a strong surface wind at 20-30 kmph on Sundays, air quality might see an increase.
Air quality system and weather forecasting and research (Safar), pollution monitoring bodies under the Ministry of Earth, said, “Aqi Delhi is likely to increase to the end of the ‘very poor’ category because the surface wind becomes stronger, spreading air pollutants.
Strong northwest increases emissions transportation from the propeller.
The share of emissions burning residue plants in PM2.5 is 41% (effective fire resistant 5,159).
