In what could be the largest single fog episode across the globe, a layer of unbroken fog has formed over 2,000 km across the Indian subcontinent. It started from central Pakistan in the west, continued through the Indo-Gangetic plains and ended near Tripura. This massive blanket of fog on Wednesday is being termed as “Superfog”. This spread of massive fog was larger than others spread in places like China, Italy and California valley, Wion News said.
The fog that started on Christmas covering eastern part of Uttar Pradesh and Bihar soon spread to the west, including Delhi by the end of the year. On January 2, It spread to Punjab and went on to move west into Pakistan. The severe fog affected rail, road transport and aviation causing a dip in day temperatures across the entire region.
Insat 3D, which captured the image in its daytime multi-channel fog detection system, said that the fog was covering at least four countries including Pakistan, India, Nepal and Bangladesh. The superfog actually began on Christmas Day in eastern Uttar Pradesh and Bihar. In previous years, only fog episode compared to this scale was reported from the same region only.
