Polar low development over the North Atlantic under a warmer climate is assessed using simulations of an atmospheric–oceanic coupled general circulation model, specifically with regards to the evolution of large‐scale atmospheric variability described by weather regimes, and their links with lower‐layer static stability. While a relationship has been identified for the present climate, under a warmer climate, polar low favorable conditions are expected to occur less often, and the large‐scale circulation variability appears to have reduced influence on stability, and thus, on polar low occurrence.
