New Delhi, Nov 5 (UNI) The national Capital’s air quality improved sharply on Wednesday, with the AQI at 202 from 291 a day earlier, according to the Central Pollution Control Board’s (CPCB) 4 pm national bulletin. Both readings fall in the “poor” category.
Meteorological factors, especially northwesterly winds, played a key role in dispersing pollutants and improving Delhi’s air, weather experts said.
“Swift and continuous northwesterly winds, gusting up to 15 kmph over the past 12-15 hours, have dispersed air pollutants and improved Delhi’s air quality,” said Mahesh Palawat, Vice President of Skymet Weather Services.
He said winds that were calm earlier picked up to around 5 kmph on Tuesday night and strengthened to 10-15 kmph through Wednesday morning and afternoon, gradually dispersing pollutants and improving Delhi’s air quality.
According to data from the Sameer App, Delhi’s air quality showed a similar pattern of gradual improvement, with the city’s average AQI recorded at 226 at 9 am on Wednesday, dropping to 205 at 2 pm and further to 197 by 7 pm.
The Capital’s air quality is unlikely to worsen in the next few days, owing to the sustained winds from the Northwest region, Palawat added.
Meanwhile, the India Meteorological Department (IMD) on Wednesday forecast northwesterly winds through the day, with speeds going up to 15 kmph over the next few days.
