Meteorologists recorded supercell thunderstorms in the Perm Territory on August 2.
According to the GIS Center of the Russian State National Research University, this is an unexpected phenomenon. According to experts, supercell thunderstorms were formed under the influence of a sedentary front oriented from west-north-west to east-southeast.
Ministry of Emergency Situations: Perm Territory will be covered with rains and thunderstorms August 4 “At heights, it corresponded to a jet stream with a wind speed of up to 110 km / h at a level of 300 hPa, which is favorable for the occurrence of long-lived convective storms and supercells. However, according to short-term forecasts of the main numerical models of the atmosphere, active convection at the front was not expected,”the experts explained.
The most powerful supercell was formed near Berezniki, and behind it another one was formed, which passed over Gubakha. In Cherdyn, there was a thunderstorm and hail. In the village of Romanovo, which is located not far from Berezniki, there was a squall that brought down trees on the highway.
“When the supercell passed over Gubakha, hail with a diameter of 10-15 mm and heavy rainfall (18 mm of precipitation) were observed. Also in one of the photos you can see FunnelCloud - a cloud-funnel. Perhaps a tornado could have formed in the Gubakha region,”the meteorologists said.
