New Delhi: Delhi air quality, which remains in the “severe” category for three consecutive days, is upgraded on Monday and touches a higher end of the “very bad” category.
The overall air quality index (AQI) is 390 compared to 429 on Sundays.
Smog continues to emerge above the city and the share of burning stumps in PM2.5 Delhi reduced from 48 percent on Sunday to 30 percent on Monday.
Experts say air quality touches the “very bad” category mainly due to reducing the share of propellers.
Gufran Beig, Director of the Founder Project, air quality system and weather and research estimates (Safar), said, “Although the number of fires increased from 4,189 on Sunday to 5,400 on Monday, the contribution of the propeller lights up to 30 percent.
The wind direction is beneficial for Transportation pollutants, but the wind speed of the transportation level has diminished and smoking from burning stumps will take longer to reach Delhi.
In addition, life pollutants are released from burning stumps only 2-3 days and can die on the road if the speed is low.
“However , a weather expert said, “When the wind west to northwest, the component of the dust increased and the agricultural fire section declined.” Even though the local wind speed was picked up during the day, meeting officials said it was almost the same as Sunday.
RK Jenamani, senior scientist at the Indian Meteorology Department, said, “The average wind speed of 8-10 kmps was recorded between 8am and 16:30, which slowed at night.
However, there was an increase in marginal in smog because of the visibility of 1,000- 1,800 meters recorded in Safdarjung and Palam in the morning.
“The minimum temperature on Monday fell to 13.6 degrees Celsius.
Dipankar Saha, Former Head in the CPCB Air Laboratory said, “The air quality entered from the severe category to very poor due to the increase in ventilation coefficients in the Indo-Gangetic plain Of Bengal is clear because there is no depression.
The sky is clearly without the cloud formation and high mixing layer higher than the last few days.
“Air quality is likely to remain in the category” very bad “.
Safar said, “The wind comes from the northwest in 925MB profitable for transport pollutants related to the stump to Delhi.
However, the impact on PM2.5 has been reduced as wind speed.
AQI is likely to increase, but still in a very bad category.”
