New Delhi [India], October 24 (ANI): The national capital is likely to see slight improvement in its Air Quality Index (AQI) on Sunday as the air quality is expected to shift from the "very poor" to "poor" category, Dr Vijay Kumar Soni, Head of Environment Monitoring and Research Center (EMRC) said on Saturday.

However, no significant improvement is expected in the next one to two week and the AQI is likely to fluctuate between "poor" and "very poor" categories.

"Tomorrow, Delhi's AQI will go from very poor to poor category. There is a possibility of improvement in coming two to three days but it will shift between the two categories for the next couple of weeks because of calm winds," Soni said.

"Since we do not see much wind and rain in the winter months, the air becomes stagnant and pollution is likely to increase. We can expect improvement if there is a western disturbance. If not, the AQI will fluctuate between the two categories," he added.
