The Increasing Efficiency of the Poleward Energy Transport Into the Arctic in a Warming Climate
Abstract This study quantifies the contribution to Arctic winter surface warming from changes in the tropospheric energy transport (Ftrop) and the efficiency with which Ftrop heats the surface in the RCP8.5 warming scenario of the Community Earth System Model Large Ensemble. A metric for this effici...
