Meteorologists Have Named The Cause Of Large Forest Fires In The Arctic

The cause of large-scale forest fires, which are observed in the Russian Arctic, Canada, and Alaska, are frequent stable anticyclones, scientific Director of the hydrometeorological center Roman Vilfand told reporters.

According to Avialesookhrana, the area of forest fires in the hard-to-reach forests of Siberia exceeds 1.5 million hectares. According to the hydrometeorological center, the highest fire risks are in the North of the Krasnoyarsk territory and Yakutia.

"In the second half of the XX century, meteorologists rarely predicted fire-dangerous situations in the Arctic regions. Why is there now information about the occurrence of fires? Very high temperatures, forests are burning everywhere in the Arctic territory (in Alaska and Canada, too-ed.). What is the reason for this? There is a change in circulation, meridional processes are formed more often, and this is the key to the formation of a stationary anticyclone," Wilfand said.

He explained that during low-cloud weather, the underlying surface is constantly heated. Also, in the Arctic, the sun does not go below the horizon in summer, so the earth does not cool down, which significantly increases the risk of wildfires.

It is impossible to say in advance where the anticyclone will be, but in the polar regions they will be repeated more and more often, Vilfand added.
