The forecaster named the reason for the fog in the European part of Russia: Society: Russia: Lenta.ru
The leading expert of the Phobos weather center, Mikhail Leus, named the reasons for the dense fog in the central part of European Russia and the timing of its dispersal. The specialist shared his forecast in a conversation with Lenta.ru.
Earlier, the press service of the Moscow Emergency Situations Directorate reported that the thick fog in Moscow, which formed on Monday evening, November 1, will dissipate by 2 pm on November 2. In the Moscow region department of the department reported that the fog will last until 15 o’clock in the afternoon.
Leus said that the fog formed the day before, November 1, is observed in many regions of Russia: from the shores of the White Sea in the Arkhangelsk region in the north to the territory of the Samara and Saratov regions in the south.
“In meteorology, such fog is called radiation fog. Do not be intimidated by this word, nothing to do with the very radiation that deals with nuclear fission. This refers to radiation cooling. That is, the process of cooling the earth’s surface by transferring heat to the atmosphere. Quite a sharp drop in temperature leads to the formation of fog under some additional conditions: high air and anticyclonic conditions, – said the forecaster.
The reason for the fog was the anticyclone leaving the central part of European Russia, Leus added. Over the past day, the forecaster noticed that the temperature in this area dropped sharply by six degrees. This provoked the condensation of water vapor in the atmosphere and became the formation of fog, he summed up.
“I think that in the next hour or two the fog will gradually subside. It will become less dense and turn into the so-called stratus dense clouds of raised fog. We will see very little sun today, which will limit the daytime warming up. If yesterday in Moscow it was plus 9, then today at best it will be 5-6 degrees Celsius, “- said Leus.
The traffic police asked Muscovites to abandon their private cars due to poor visibility. The department noted that drivers behind the wheel need to increase the distance between road users, reduce speed and monitor the lateral interval.
