Scientists named the cause of forest fires in the Arctic

(ORDO NEWS) — The cause of large-scale forest fires that occur in the Russian Arctic, Canada and Alaska are frequent persistent anticyclones, Roman Wilfand, the scientific director of the Hydrometeorological Center, told reporters.

According to Avail Okhrana, the area of ​​forest fires in the inaccessible forests of Siberia exceeds 1.5 million hectares. According to the Hydrometeorological Center, the highest risks of fires are in the north of the Krasnoyarsk Territory and Yakutia.

“In the second half of the 20th century, meteorologists infrequently predicted fire-hazard situations in the Arctic regions. Why is there now information about the occurrence of fires? .. Very high temperatures, forests burn everywhere in the Arctic territory (in Alaska and Canada too – ed.). With what is it connected? There is a change in circulation, meridional processes are increasingly being formed, and this is the key to the formation of a stationary anticyclone,” said Wilfand.

He explained that during low-cloud weather, the underlying surface constantly heats up. In addition, in the Arctic, the sun does not go below the horizon in summer, so the earth does not cool, which significantly increases the risks of natural fires.

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, added Wilfand.
