Extreme Arctic warming scenario is studied with an idealized numerical experiment of polar warming. We employ the Community Earth System Model version 1.0 (CESM1.0) in this study. The control starts from the rest of the data with standard configurations (using a CO2 concentration of 285 ppm). Overall, the model climate reaches a quasi-equilibrium state after 1,000 years of integration (Yang et al., 2015). A surface albedo perturbation experiment (0.1A) is carried out to achieve global warming and AA. During years 1501-2000, 0.1A is “parallel” to control, with the same initial conditions at the end of year 1500, and it reaches quasi-equilibrium after the 500-year integration. In the numerical result study, we focus on the equilibrium responses using the monthly averaged fields over the last 200 years of integration. Here we offered SAT anomaly, 500 hPa geopotential height, surface wind anomaly, and surface horizontal heat advection anomaly.
