What’s Radiation Fog
According to the US space agency, this type of fog is formed at night when the temperature on the ground is cooled, the air speed is low and has enough moisture. This fog engulfs the Gangetic plains to the valleys.
This type of fog has the most impact on the traffic system. In recent times, due to fog, rail traffic and road traffic have been badly affected. The chances of accident in the fog also increase.
According to a report, in the year 2022, more than 14 thousand deaths occurred in road accident while more than 15 thousand people were injured. Due to lack of rain, people in North India are facing dry cold this year.
The Modis (Moderate Regulation Imaging Spectroidarometer) on NASA’s Terra Satellite took this image on the morning of 15 January 2024. It had a dense fog from Islamabad in Pakistan to Dhaka, the capital of Bangladesh.
In some places the fog sheet looks light, which is an indication that they are areas of Delhi, Agra, Meerut and Rohtak. NASA has called them Heat Island.
