“Due to a sharp drop in temperature and, as a result, sublimation of water vapor, a frosty fog formed in places with a deterioration in visibility up to 100 meters.
Such frosty fogs are typical for Siberia and the Far East with their sharply continental climate and severe frosts,” Tishkovets said.
He noted that the fog would dissipate by noon.
Earlier, the scientific director of the Hydrometeorological Center of Russia Roman Vilfand, in an interview with Komsomolskaya Pravda radio, said that a sharp warming is expected this week in the south of the European territory of the country.
