We analyze the Northern Hemisphere atmospheric response to Arctic sea ice decline in the CNRM-CM6 model (130km resolution, 91 vertical levels) using atmosphere-only experiments that follow the PAMIP protocol described in Smith et al. (2019). The high-top atmospheric component of CNRM-CM6 is forced by the same pattern of SST but different idealized patterns of sea ice that correspond to i) pre-industrial conditions (PI), ii) present day conditions (PD), and iii) future conditions (FUT)

We focus on the cold season response (October to March) and describe the atmospheric response for different sea ice forcings applied either in to whole Arctic or to specific regions of the Arctic.
