Vilfand said the trend of hotter temperatures and sunnier weather was caused by climate change and a change in atmospheric circulation, with polar anticyclones -- phenomena that bring sunny skies -- becoming more frequent.
The lack of clouds, in turn, causes the ground to heat up during the Arctic summer, he said.
Previously "meteorologists didn't note fire hazardous situations in the polar regions often," he said, but this is now changing due to these patterns.
"It's an astonishing situation. Anticyclones happen more and more often and you can never predict where they are going to occur," he said.
