From ‘severe’, Delhi sees AQI dip to ‘poor’ in a day

The agency has forecast the spell of relatively clean air to continue for the next 48 hours. The AQI likely to touch “moderate” level in the next 24 hours, it added.

Kuldeep Srivastava, scientist, IMD, and head, Regional Weather Forecasting Centre, Delhi, said, the northern plains saw light to moderate showers on Sunday, with snowfall in the mountains. With withdrawal of western disturbance, wind speed is likely to remain good.

“On Sunday, wind speed touched 24 km/hr, and it was high on Monday too. A combination of rain and good wind speed has completely settled the pollutants and is allowing faster dispersal of local emissions,” he added.
