Delhi's air quality improves to 'very poor' with change in wind direction

The national capital recorded its air quality in the 'very poor' category on Thursday morning even as experts said the situation was “much better” compared to two days ago when pollution levels were above the emergency threshold. A change in the wind direction -- from north westerly to north-north easterly -- was the reason behind the dip in pollution levels as it reduced the contribution of stubble burning significantly, according to government agencies and weather experts.
