AQI in Delhi dips once again
The air quality issue of Delhi isn't a new one, Delhi has long been the victim to an extreme air pollution and it seems that it'd going to be here for long. Every year around fall, the air quality index of Delhi plummets down owing to stubble burning in the nearby states and an overall shift in weather. Much like last few years, Delhi air quality this year too, has taken a plunge and if AQI trends and reports are to be believed, it is only going to get worse.
AQI on Friday was recorded at poor and very poor levels, bettering slightly from the past few days. Yet, according to a report by SAFAR (System of Air Quality and Weather Forecasting And Research), the relief is only temporary.
System of Air Quality and Weather Forecasting And Research or SAFAR on Friday sent out an update which foretold that the AQI in Delhi is about to take a turn for the worst.
Delhi's air quality index has been under much scrutiny lately, the AQI on Wednesday was recorded at 309 while on Thursday the overall AQI stood at 274. The AQI on Friday dipped a few points and was recorded at 245, still in the poor category. Yet according to a forecast by SAFAR, the improvement is fleeting.
According to a forecast issued on October 18th, the AQ is expected to dip further and end up at very poor. The stubble burning in Punjab, Haryana, Western UP and the nearby area is moderate, yet from 20th October, a shift in wind direction to northwesterly will lead the air quality to end up in the middle spectrum of the very poor category.
SAFAR also forecasts that by the fourth week of October a further deterioration in the air quality of Delhi may be observed while the temperature will also start cooling. The low wind velocity and a decrease in temperature during the last legs of October will abet particulate matter formation and accumulation of pollutants.
With the winters approaching, the air quality in Delhi is going to drop quite a bit. Let's hope that the initiatives taken by the government and civic authorities work their magic. If the wind velocity remains favourable and a crackdown on firecrackers is practiced, the condition might not worsen. If not, the air quality in Delhi is expected to jump to category.
