He explained that the storm was associated with a cold front that brought cold air from the Arctic. The front was moving at high speed (60 km/h) and expelling warm air upward (meteorologists call this process convection).
“This caused the formation of clouds up to 5 to 5.5 kilometers high, which stimulated storm activity,” said the country’s chief meteorologist.
Recall that on the morning of January 11 in Moscow the air temperature rose to zero degrees, after which the weather worsened sharply. The capital region was hit by a cyclone.
