Smog continued its cover and the visibility was reduced to 500 metres early in the morning today. However, it improved swiftly to 800 metres at 11.30 am as winds blew away the fog.

Saturday the visibility was reduced to 300 metres at 9.30 am as thick smog created by smoke and fog descended in the wee hours.

"A complete absence of wind was one of the reasons for Saturday's condition, but things are better today as it is windy," a Met department official said.

The temperature recorded at 27.6 degree Celsius was also a degree and half higher on Sunday at 11.30 am compared to Saturday, the official said.

Smog is a frequent phenomenon in winter and results when carbon emissions interact with the atmosphere to form airborne particles which do not disperse due to fog. Vehicular pollution is the main cause of smog in winter.

Low visibility resulted in two accidents yesterday. Five railwaymen, including an officer, were run over by Delhi-bound Dehradun Janshatabdi Express near Ghaziabad.

In another accident, seven students were injured when a school bus was hit by a truck at around 7.30 am near Kashmere Gate area.
