New Delhi: Air quality in Delhi and adjoining regions improved from “severe” to “very poor” on Wednesday as wind speed picked up due to western disturbance over north India and dispersed pollutants. “The major reason for the improvement in Delhi’s air quality is increased surface wind speed (4kmph from 2.5kmph) which will disperse pollutants slowly,” System of Air Quality and Weather Forecasting and Research (SAFAR) said in its forecast.
However, the agency said, the drizzling in some parts of the national capital was proving to be “counterproductive” as it could not wash away particulate pollutants, instead increased the air holding capacity by introducing more moisture. “Other than wind speed, rest all meteorological factors are likely to be unfavourable even tomorrow (Thursday),” it said.
