Short summary
In this paper, two global climate models (NorESM1-M and CCSM4) are compared to an observational-based data set (ERA-Interim) for their ability to simulate historical Arctic storminess in autumn. With this in hand, the models are run through the 21st century. We find an overall significant increase in precipitation expected, with generally fewer and weaker storms in midlatitudes and partly more and stronger storms in high-latitudes. The tendencies are strongest in areas of Arctic sea ice retreat.
