From Pakistan to Tripura, 'superfog' is the reason you can't see a thing

The past few days have heralded the onset of the “superfog” in parts of 
North and Central India. According to newspaper reports, the 2000 km 
long blanket of fog has shrouded four countries - India, Pakistan, Nepal 
and Bangladesh.

The dense fog or superfog as its popularly being called, originated in 
Central India during Christmas last month and spread to areas around the 
Indo-Gangetic belt, including parts of Pakistan and Bangladesh.

The sueperfog has considerably reduced visibility in and around North 
India. Aviation, rail and road transport are the worst hit.

Additionally, the blanket of fog has caused a sharp drop in day time 
temperatures across the affected regions.

According to the Indian Meteorological Department (IMD), at least 15 
airports in the country reported moderate to severe fog between 6.30am 
and 9.30am on Wednesday, 4 January,

These include Agartala, Patna, Gaya, Guwahati, Gorakhpur, Allahabad, 
Agra, Lucknow, Varanasi, Rae Bareli, Chandigarh, Jammu, Ludhiana and 
Pantnagar. The worst hit was Amritsar, which had visibility below 100m 
for 18 hours, from 6.30pm on Tuesday until 12.30pm on Wednesday.
