Zorgt een verandering in de structuur van de jet stream voor langere perioden van een bepaald weertype?
Wavier jet stream 'may drive weather shift'
New research suggests that the main system that helps determine the weather over Northern Europe and North America may be changing.
The study shows that the so-called jet stream has increasingly taken a longer, meandering path.
This has resulted in weather remaining the same for more prolonged periods.
The work was presented at the annual meeting of the American Association for the Advancement of Science (AAAS) in Chicago.
The observation could be as a result of the recent warming of the Arctic. Temperatures there have been rising two to three times faster than the rest of the globe.
