Missing wind variability means future impacts of climate change may be underestimated in Europe and North America

Extratropical winds have a strong influence on climate in extratropical regions, and are known to vary from decade to decade. However, their variability is currently not factored into climate models making predictions for future climates in these regions. Researchers inserted these into predictions for how extratropical climates will change by the middle of the century, and found uncertainty increased significantly, meaning unusually hot, cold, dry or wet decades are likely to be more frequent here than previously thought.
