Air quality to worsen, temperature to drop in northwest as New Year approaches
Most towns and cities in northwest India recorded poor and really poor category air on Saturday. While Delhi has an air quality index (AQI) of 324 within the very poor category, NCR cities of Faridabad, Gurugram and Noida recorded poor air quality. The air quality is probably going to deteriorate beyond December 27 thanks to a change in wind speed, related to an approaching western disturbance. “The wind speed increased to 10 to fifteen kmph on Friday which helped improve the air quality but we expect AQI to deteriorate again on December 27 and 28 to the lower end of the very poor or severe category. When a western disturbance approaches, winds hamper , leading to an accumulation of pollutants,” said VK Soni, scientist at IMD’s air quality management division.
