The thick fog that came to the metropolitan area is a natural meteorological phenomenon associated with a sharp cooling. It is not connected with external factors.
According to Roman Wilfand, scientific director of the Hydrometeorological Center of Russia, it has nothing to do with the manifestation of external factors.
In a conversation with Izvestia, the expert said that the fog in question is called radiation cooling. Wilfand stressed that it has nothing to do with radioactivity.
"Energy cooling of the underlying surface in the absence of clouds," the edition quotes the words of the head of the Hydrometeorological Center.
He also added that the fog that covered Moscow was a predictable phenomenon, which had been previously warned about.
