"Thereafter a slight improvement is predicted. At present, wind speed is slow and hence not good for air quality as it allows pollutants to get accumulated. Humidity continues to be high and temperature is likely to cool, both unfavourable," the SAFAR said in a report.
Delhi's air quality showed a slight improvement on Thursday due to increased wind speed, favourable for dispersion of pollutants, and settled in the poor category.
