Delhi pollution has decreased significantly during the last few days. Until December 10, pollution levels were severe. The levels also reduced across the nearby areas of Faridabad, Gurugram, Noida, and Ghaziabad on December 11 due to the rain and thundershower activities over most parts of Northwest India including Delhi-NCR.

The rains helped in washing away the pollutants which were suspending in the lower atmosphere since many days. At present, moderately dry and cold winds from snow-clad Himalayas are blowing over Delhi and adjoining region.
These winds are not allowing pollutants to accumulate. Hence, the pollution levels have slid down to poor from very poor and severe at many places. Though local pollution is still there but moderate winds are blowing it away continuously.

As per weathermen at Skymet Weather, it is anticipated that pollution may make a comeback as soon as wind speed would now decrease. However, this would not happen for another four to five days as we do not expect winds to die down so soon.
As the temperatures are falling continuously due to the cold northwesterlies, fog has become more prominent during early morning and late night hours. It must not be mistaken with smog because visibility level is reducing due to fog. Fog consists of condensed water droplets and not smoke and dust particles which are present in smog.
Hence, it is not pollution but pure mist and fog. It is expected that Delhi would breathe easy for next few days.
