Cold air outbreaks (CAOs) in the Arctic are situations in which a low level mass of cold air initially situated over the sea ice is advected across the ice edge and continues over open water. This process is accompanied by the formation of a convective boundary layer that deepens rapidly, featuring strong surface heat fluxes as well as the formation of low-level mixed-phase clouds. The dynamics in the CAO boundary layer are often complex, as illustrated in Fig. 2. Often these clouds are organized into streets, which at some point downstream of the ice edge tend to break up into bigger individual cells. These cells, often arranged into a spoke-pattern, | Cold air outbreaks (CAOs) in the Arctic are situations in which a low level mass of cold air initially situated over the sea ice is advected across the ice edge and continues over open water.
