The government today denied any "abnormal" weather conditions like huge fog over parts of Northern India, but said the usual phenomenon of moderate haze has been reported at some places at certain occasions during the month.
"Abnormal weather conditions like fog like huge fog over part of northern India has not been reported recently. However, the usual phenomenon of moderate fog/ haze has been reported at some places on certain occasions during the month of November 2015," Minister of State in the Ministry of Earth Science, Y S Chowdary said in a written response to a question in the Lok Sabha.
Incidentally, SAFAR, a Ministry of Earth Sciences body which records air pollution level have termed the air quality of Delhi as "poor" to "very poor" since last few days.
He added that fog is largely prevalent over north/ north west India due to the stable atmospheric conditions locally that keeps the suspended pollutant particles trapped in the lower atmosphere close to surface.
"The increased quantum of vehicular traffic/ rapid industrialisation over the years is one of the reasons for the increased concentrations of pollution," he said.
