Two days after Diwali,Delhi continues to be enveloped in a thick layer of smog. Prevailing weather conditions,especially the lack of wind,did not allow air pollutants to disperse and visibility was reduced to 600 m at IGI Airport and Safdarjung Airport in the afternoon.
The Indira Gandhi International (IGI) Airport Met office attributed the low visibility to pollutants released in the air following burning of crackers in Diwali. Diwali pollution is unique in Delhi and such celebrations have a high capability of doing extreme damage to the air quality, an IGI Met official said.
IGI Met officials also blamed the weather for the smog.
Wind remained persistently low and thereafter was calm for the last 18 hours and the stability in the air was further increased due to very slow movement of the western disturbance. Hence the Diwali smog has been trapped in this stable layer over Delhi-NCR, R K Jenamani,director in-charge of the IGI Met office,said.
However,Met officials said the smog is expected to clear with the western disturbance moving across Delhi from Wednesday. Setting up of easterly winds by Wednesday afternoon… (will lead to) smog conditions improving significantly, Jenamani said.
The Central Pollution Control Board noted that levels of particulate matter-10 (coarse particles) were higher this Diwali as opposed to the previous year.
The India Meteorological Department (IMD) said rain and thundershowers are expected on Wednesday and Thursday.
Meanwhile senior traffic police officers said that the responsibility of ensuring that traffic movement isnt affected by the smog was with the road-owning agencies and that they had deployed officers at sensitive locations.
The weathermen said the foggy conditions would prevail for a longer time in the plains of Northwest India,including Delhi-NCR,for a few days from November 9.
