Delhi’s air top quality remained “poor” on Sunday and is most likely to deteriorate additional amid a dip in the mercury and the wind speed. The city’s air top quality index (AQI) was 245 at 9 am. The 24-hour typical was 231 on Saturday, 137 on Friday, 302 on Thursday and 413 on Wednesday.
An AQI amongst zero and 50 is thought of “good”, 51 and one hundred “satisfactory”, 101 and 200 “moderate”, 201 and 300 “poor”, 301 and 400 “very poor”, and 401 and 500 “severe”. The maximum wind speed was 15 kmph on Saturday. It is most likely to be 8 to 12 kmph on Sunday and Monday, according to the India Meteorological Department.
Winds are predicted to slow down on Sunday. Therefore, Delhi’s air top quality is most likely to deteriorate additional and stay in the “poor” to “very poor” category more than the subsequent two days, it stated. The minimum temperature was 7 degrees Celsius on Sunday and the maximum is predicted to settle about 26 degrees Celsius, the climate division stated.
Calm winds and low temperatures trap pollutants close to the ground, even though favourable wind speed aids in their dispersion. The share of stubble burning in Delhi’s pollution has also decreased drastically as the harvesting season has ended The contribution of stubble burning in neighbouring states to Delhi’s PM2.5 levels was 4 % on Saturday, 2 per cent on Friday and just 1 per cent on Thursday, according to the Ministry of Earth Sciences’ air top quality monitor, SAFAR.
